One of the basic topics in population geography is how the population distributes and changes on terrain gradients. With the improvement of data accuracy and quality, it is feasible to conduct macroscopic analysis for this question based on kilometer grid cells. This study analyzed the distribution and change characteristics of China's population on the gradients of elevation, ruggedness, and slope from 2000 to 2020, using methods of frequency distribution statistics, based on 1-km grid statistical cells, and using spatial demographic datasets (WorldPop) and digital elevation model datasets (SRTMGL1). The effects of different digital elevation model datasets (including ASTER GDEM and SRTMGL1) and spatial demographic datasets (including WorldPop, LandScan, and GPW) on the results were also compared and the differences between the 1-km grid and 100-meter grid data were further explored with SRTMGL1 and WorldPop. The results show that: 1) The population increasingly tends to be distributed at the lower position of terrain gradients. The half-balance points of the population distribution on elevation, ruggedness, and slope gradients were 95.6 m, 50.7 m, and 3.01° respectively in 2000, and decreased to 77.0 m, 46.8 m, and 2.88° in 2020. 2) Dominant area of population distribution relative to land area has been stably located at a lower position of terrain gradients. The upper boundary of the dominant part of the population over terrain (MU) is stably located at the elevation of 520 m, the ruggedness of 137 m, and the slope of 6.84°, respectively, and the population dominance rate rose from 0.511, 0.248, and 0.217 in 2000 to 0.522, 0.274, and 0.255 in 2020, respectively. 3) Different spatial demographic datasets have no effect on the distribution and change pattern of population on terrain gradients, while DEM datasets have significant effects on the ruggedness gradient and slope gradient distribution of population. There is no difference between 1-km grid and 100-meter grid data for this study, and the 1-km grid dataset is recommended for the study of population distribution at the national scale and above. This study provides a new basic reference for understanding of the relationship between population distribution and terrain in China at the kilometer grid scale.

With the advent of the post-industrial era, a "green turn" has gradually become the basic principle of global urban renewal. However, green initiatives and practices in urban renewal often focus on environmental sustainability, neglecting the green gentrification that can be triggered at the social level. In the context of urban renewal in China, urban greening practices have emerged with many representations similar to the phenomenon of green gentrification, but this has not attracted the attention of scholars in China. This study adopted a qualitative research method to investigate the effects and mechanisms of green gentrification in the context of urban renewal, taking the greening practices of urban agricultural parks as an example. The study found that: 1) In the context of urban renewal, urban greening practices imply a logic of gentrification in action, and the postmodern aesthetic and experiential landscape it creates becomes a place representation of green gentrification. 2) Greening practices oriented to serve the urban elite have triggered landscape segregation and stratification, but under the guarantee of the Chinese land tenure and management system, the indigenous people are not displaced but receive dividends from the recapitalization of the land. 3) The government, village collectives and residents, and developers have formed green growth alliances to meet their political and economic demands for the purposes of urban governance, land rents, and economic interests, respectively, eventually forming a government-led green gentrification operation mechanism. This study empirically analyzed green gentrification, which originated in western societies, in the institutional and social contexts of China, expanding the connotation and explanatory validity of green gentrification in the context of multiple geographies, and providing new theoretical perspectives and practical insights for understanding the change of human-land relationship in the context of urban renewal in China.

Production of space systematically integrates Marxism and spatial theories into a materialistic system with both dialectical and historical thinking, opening up a new horizon for interpreting and analyzing spatial practice processes. Using the CiteSpace bibliometric method and based on publications in China and in the field of production of space, combined with in-depth reading of typical literature, this study examined the progress of the application of the theory of production of space in the field of urbanization research in China, and summarized the overview, highlights, and shortcomings of research. The results indicate that: 1) The rapid development of urbanization in China and the expansion of the dissemination and influence of the Western theory on the production of space have jointly promoted the relevant research in China, which is characterized by diverse objects, broad themes, flexible perspectives, and a combination of practical interpretation and problematic criticism, focusing on the correspondence between foreign theories and local practices. 2) The generalization of spatial patterns of urbanization and the critique of urbanization effects are the two key points of the application of the production of space theory. The former is to apply production of space to sort out diverse and specific localization practices, while the latter is the revelation of contradictions in specific spatial production practices based on human-centered values. There still exist several shortcomings: 1) The lack of attention to the richness of historical practice and the special focus on the logic of capital have led to the suspicion of economic determinism and relatively neglected other important areas such as everyday life. 2) Insufficient attention to the localization of historical practices and the biased dogmatic appropriation of Western theories has limited the growth of critical theoretical innovation. 3) Insufficient attention has been paid to the need to guide practice, and the value of Marxism for guiding practice is still limited. 4) From the standpoint of historical materialism, the outlook of theory application was proposed in the light of the specific trends and needs of high-quality development of urbanization in China, that is, from productive space analysis to living space concern, from spatial problem analysis to the construction of a Chinese system of theories, and from the interpretation of spatial theory to the guidance of spatial practice.

Regional economic integration has become a necessary path to promote regional high-quality development in China, but relevant studies from the perspective of private enterprise investment are rare. Using statistical analysis and social network analysis methods, we analyzed the process of regional economic integration through the evolution of private enterprise investment network in the Lanzhou-Xining (Lan-Xi) urban agglomeration from 2013 to 2021, and explored the mechanism of change. The study showed that: 1) The Lan-Xi urban agglomeration was in the middle and late stage of industrialization, but the private enterprise investment network still showed an obvious inter-provincial "dual-core separation" structure, with a relatively high level of integration in Qinghai Province, and there were large differences in the inter-provincial investment behavior of different industries within the urban agglomeration. 2) The formation of the dual-core separation structure of the private enterprise investment network was mainly influenced by the current development stage of the region, and the provincial capital cities played a dominant role in this polarization, leading to extremely weak inter-provincial investment ties. 3) The administrative region economy and institutional thickness exerted a deterrent effect on the inter-provincial investment of private enterprises through external environment and internal decision making, respectively. Based on the above conclusions, starting from the low level of regional economic integration in the Lan-Xi Urban Agglomeration, this paper puts forward relevant policy recommendations to promote the formation of inter-provincial complementary regional economic layout with the goal of high-quality development.

In the context of a new technological revolution and the rise of public health awareness, wearable technology has experienced rapid development and widespread adoption, deeply integrating into the practice of urban resident leisure-time physical activities. However, the current theoretical exploration on the spatiotemporal effects and mechanism of residents' activities lags far behind the actual development needs. From an interdisciplinary perspective, this study focused on the comprehensive and systematic theoretical research of geography. The initial step of this study involved a quantitative analysis of the literature using the CiteSpace 5.7 software, providing insights into the general research trend and direction in the field. Then, the study summarized the changes in urban resident leisure-time physical activities under the influence of wearable technology from three perspectives: digital decision making, new spatiotemporal characteristics, and diversified experiences. The research implications underscore the need to deepen the understanding of the decision-making mechanism of resident leisure-time physical activity, strengthen the analysis of complex spatiotemporal rules of leisure-time physical activity, and emphasize research on satisfaction with leisure-time physical activity experiences in multiple situations. Furthermore, the article proposed a research framework for urban resident leisure-time physical activity under the influence of wearable technology. It stressed the importance of the crossover and integration of multidisciplinary theories, with a call to enrich analyses across five dimensions: research subject, technology, activity, space, and time. Additionally, the article argued for innovating research methods, expanding research content, and strengthening the application of health-oriented spatial planning practices. This comprehensive approach may enhance the understanding of the dynamic relationship between wearable technology, urban spaces, and resident leisure-time physical activities, and provide valuable references for urban spatial planning practices guided by residents' activity needs in the digital health era.

High tide flooding (HTF)—a kind of minor coastal flooding that usually occurs near the high tide level, becomes more frequent under climate change. It has a certain impact on the coastal socioeconomic system and natural environment, and is a hot issue in low-lying coastal cities. This article examined the definition of HTF, and systematically summarized the main progress of HTF research in terms of its drivers, impacts, risk assessment, and frequency forecasting. In the future, it is recommended to strengthen the research on the drivers, risk assessment, and forecast of HTF frequency. These include extensive monitoring of HTF, quantifying the role of interactions between factors leading to HTF, comprehensively assessing HTF risk, and accurately predicting HTF frequency. All these works will finally contribute to the disaster prevention and mitigation of HTF in coastal cities.

Urban-rural economic circulation is an important part of the macro economic circulation in China. Optimizing urban-rural economic circulation is a fundamental project for building a new development pattern. This study analyzed the connotation of urban-rural economic circulation from four dimensions: supply and demand relationship, industrial linkage, factor flow, and circulation carrier, and constructed an evaluation index system, taking 2010-2020 as the study period and the Jianghan Plain as the case study area. It comprehensively applied the entropy weighting method and the obstacle degree model to reveal the characteristics of change of the spatiotemporal pattern of urban-rural economic circulation in the study area, and explored the path of its optimization. The results show that: 1) During the study period, the level of urban-rural economic circulation in the Jianghan Plain region was low but continued to grow unevenly. The composite and sub-dimensional indices (supply and demand relationship, industrial linkage, factor flow, and circulation carrier) of urban-rural economic circulation grew from 0.2164, 0.0616, 0.0534, 0.0641, and 0.0373 to 0.4095, 0.1308, 0.0850, 0.0990, and 0.0947, with an average annual growth rate of 8.92%, 11.24%, 5.93%, 5.45%, and 15.35%, respectively. 2) During the same period, the urban-rural economic circulation in the study area generally showed a low level of aggregation, regional differences increased slightly, and the spatial coefficient of variation increased from 0.2055 to 0.2126. The high-value areas of supply and demand relationship and circulation carrier index of the urban-rural economic circulation gradually aggregated to the main transportation arteries and the urban areas along the routes, and the spatial coefficient of variation decreased from 0.3166 and 0.5665 to 0.2636 and 0.4705, but the industrial linkage and factor flow spatial distribution characteristics were not as distinct. 3) The obstacle degree of urban-rural economic circulation in the study area showed a decreasing trend year by year, and the sub-dimension obstacle degree ranked as industrial linkage (28.20%) > circulation carrier (27.89%) > factor flow (23.98%) > supply and demand relationship (19.93%), and the top four indicator obstacle degree ranked as night-light index (11.23%) > proportion of built-up area (10.79%) > output value of agricultural services (10.65%) > loan balance of financial institutions per unit of GDP (9.82%). 4) The optimization of the urban-rural economic circulation in the Jianghan Plain region can be divided into three types and six sub-districts, including single obstacle type, double obstacle type, and triple obstacle type, and according to the different types of obstacles in each district, the appropriate development strategies for the optimization of the urban-rural economic circulation were proposed respectively. The results of this study can provide some theoretical guidance and practical inspiration for the development of urban-rural economic circulation in the new era.

Administrative division is the basic supporting unit for a country to carry out local governance. The adjustment of administrative divisions is related to the grassroots social governance system and capacity building, and constitutes a part of the modernization of the national governance system and governance capacity, which has a long-term impact on economic development and regional governance. This article systematically reviewed and analyzed the literature on China's administrative division research in the past 30 years, and summarized the development status of China's administrative division research from the aspects of history, type of models, effectiveness evaluation, influencing factors, and comparison within China and internationally. The research found that the setting of administrative divisions serves the national development strategy, and the research is closely related to national policies. The promulgation and implementation of relevant policies stimulate the research of administrative divisions, and vice versa. The study of administrative division has a strong historical continuity and spans multiple disciplines. Drawing on the useful experience of developed countries, it also has very strong local characteristics. In the process of integration of administrative divisions into national governance system and governance modernization, scientific and practical research on the setting and adjustment of administrative divisions should be strengthened. We should give full play to the advantages of multiple disciplines, strengthen the theoretical and methodological research on the setting and adjustment of administrative divisions, and comprehensively improve the effectiveness of national spatial governance.

In the process of rapid urbanization, regional human-environment relationships in rural areas have become increasingly complex, and these areas are facing the challenge of integrating limited resources to realize industrial transformation and development. From the perspective of the factor-structure-function transformation of the rural territorial system, this study elucidated the conceptual connotation and driving force of rural industrial restructuring. On this basis, it classified the typical patterns of rural industrial restructuring according to the development direction of the dominant industries, with a specific focus on Guangxi. The study then proceeded to construct the guarantee mechanism for rural industrial restructuring. The following four main conclusions were reached: 1) Rural industrial restructuring can be comprehended as the process of optimizing spatial layout, extending the industrial chain, and enhancing the industrial system through industrial cultivation, adjustment, upgrading, and transformation. This process is grounded in the integration of the basic factors of industrial development—such as labor, land, and capital—in the context of local development conditions and external market environment. Rural industrial restructuring is characterized by the diversification of subjects and business forms, aiming to achieve both the benign and balanced development of rural industries internally and the value output externally. 2) In the practice of industrial restructuring, external driving forces and endogenous development forces of the rural territorial system interact with each other to jointly promote the coupling and coordination of various factors related to industrial development. 3) Rural industrial restructuring comprises five typical patterns, including the specialization of agricultural production, the industrialization of traditional culture, the tourism-driven development, the agglomeration of manufacturing, and service-oriented commerce and logistics. 4) In terms of policy, emphasis should be placed on guiding the concentration of key factors of production in rural areas by breaking down institutional barriers; building modern rural industrial systems by optimizing the industrial structure and improving the industrial layout; and improving the benefit linkage mechanism by adhering to the principle that the central position of farmers should not be compromised. Through a comprehensive approach, an institutional arrangement can be made for promoting rural industrial restructuring and facilitating the revitalization of rural industries.

Suburban villages with superior ecological endowments can often realize rural development by virtue of landscape resources and spillover effect of big cities. But due to the rapid urbanization and urban "siphon effect", suburban villages often experience hollow problems such as labor emigration and industrial decay. Taking Yangjiamen, a traditional village in the Songshan Scenic Area, as a case study site, and based on the actor network theory, this study analyzed the process and mechanism of rural transformation by means of semi-structured interviews and participatory observation, and examined how endogenous impetus promoted rural revitalization. The results show that the case study village went through three stages of development: rural resources concentrated in the hands of rural sages, diversified industrial development feeding back to rural residents, and government-led enterprise-resident participation in diversified development, and experienced the change of rural sage→government-led→diversified governance of social networks. The dynamic mechanism changed from endogenous forces to endogenous development forces combined with external forces. This process has promoted the transformation and development of rural population, land, industry, and society, and realized the revitalization of talents, industries, organizations, culture, and ecology. This study provides some theoretical reference and practical guidance for rural revitalization in suburban hollow villages with superior ecological resource endowments.

Music geography is an interdisciplinary subject between geography, musicology, culture studies, and other disciplines. Compared with the well-established music geography in Western countries, music geography in China is still in the embryonic phase. This study attempted to provide a literature review for the progress of music geography research outside China by having a close look at its origin, development paths, essential debates, frameworks, and approaches, based on an in-depth bibliometric analysis. First, this study found that international research on music geography has extended its scope from the perspective of cultural geography to an interdisciplinary discourse and received great attention from economic geography, political geography, and urban geography. Second, the core themes of international music geography research can be generally classified into five branches: music regions and cultural diffusion, industrial clusters and networks, temporal-spatial phenomena and influences of music performance, music-based identity and cultural politics, and music geography as a special urban soundscape. In terms of theories and approaches, international music geography research can be divided into four main branches: cultural geography, geopolitics, economic geography, and urban geography, which are respectively influenced by the non-representational theory of new cultural geography, popular geopolitics and the relational turn of economic geography, and other important trends. Lastly, this article proposed that there is a great necessity to pay more attention to music research by Chinese geographers as it serves as an ideal case and instrument to inquire into geographical issues such as local identity, authenticity, and sense of place, local-global connections, creative production networks, temporary projects, urban planning, and social well-being.

Against the background of the current high degree of urban-rural spatial reconfiguration, the new constructed characteristics of happiness and its urban-rural heterogeneity of humans, which are the actors and ultimate target of development, are of great significance to the balanced and effective enhancement of the dividends of happiness in China's urban-rural development. This research introduced capital as a tool into the study of happiness in human geography, and used data from the China Family Panel Studies (CFPS) to design an analytical framework for the construction of happiness by multidimensional capital from the three dimensions of economy, culture, and society. The Probit regression model was used to empirically analyze and explore the constructed characteristics of happiness and its urban-rural differences in the context of high mobility in 2018 from the perspectives of level and structure. The results show that: 1) Chinese residents' happiness was at a high level and relatively balanced between urban and rural areas, and the constructs of urban and rural residents' happiness are diversified under the "level" perspective, that is, the basic effect of economic capital, the transformative effect of cultural capital, and the strong sensitivity of social capital contributed to the enhancement of happiness in urban and rural areas. 2) Having considered the integrity of capital "structure" and ecological niche, the impact of multidimensional capital on the construction of happiness has evolved from one-way enhancement effect to uncertainty and structuralized characteristics, especially the strengthening or missing effects caused by the dominant or deficient local ecological niche, which makes the capital dimension more complex in the construction of happiness. 3) There were significant urban-rural differences in the response strength of residents' happiness to various dimensions of capital, among which social capital showed the strongest sensitivity and the most significant urban-rural differences in the construction of happiness, which indicates that China's current new-type urbanization process should pay attention to the reproduction mechanism and effect of urban-rural social capital. The results of the study are conducive to revealing the modern and local characteristics of the happiness construct in China, and provide a basis for balanced and effective policy formulation to enhance the happiness of Chinese urban and rural residents.

Since the appearance of the "re-materializing" approach in human geography, the subjectivity of material has been reappraised in the research framework of geography of migration. This reflection helps establishing a new research paradigm that combines mobility and materiality to explain the increasingly complex migration situation in the world. Although the concept of "material turn" first appeared in the literature of social sciences, there is limited research that systematically reviews how geography of migration engages with the materialist approach. Therefore, we intended to examine the current research trends, theoretical debates, and research frontiers in geography of migration, and then construct a theoretical framework that foregrounds the interactive relationship between migration and material. This article first examined the philosophical theory of Western material research, finding that the "material turn" trend was originally rooted in Western materialism, new materialism, and body phenomenology. Second, through the quantitative analysis of the migration-related literature in geography, we found that the research engaging "material turn" in the past 10 years mainly focused on four research hotspots: 1) migration infrastructure; 2) migration material culture; 3) immigrants' bodies, emotion, and politics; and 4) more-than-human migration geography. Focusing on the key research on material theories, this article summarized the current insights in Western and Chinese geography of migration to systematically explain the agency of material during the migration process, which may shed light on the importance of material in mediating the relationship between immigrant and place. Finally, this article constructed a theorical model around the relationship of "migrant-material-place", and further put forward the research prospect of establishing Chinese localized immigration theory. The research on "material turn" not only helps to guide new theoretical trends in geography of migration, but also promotes the place integration of international and intraregional immigrants in China.

Improving the carbon sequestration and sink capacity of terrestrial ecosystems is one of the most economical and green ways to achieve the carbon peaking and carbon neutrality goals on schedule. Soil particulate organic carbon (POC) and mineral-associated organic carbon (MAOC), as important soil organic carbon fractions, are the key to understanding changes in the carbon cycle in terrestrial ecosystems. Previous studies have shown that climate warming has changed the carbon cycle of terrestrial ecosystems and affected the input of organic carbon from plants and microorganisms at the same time, but there is no unified conclusion on the response of soil organic carbon components to climate warming and their controlling factors. This article systematically introduced the framework of soil particulate and mineral-associated organic matter. The formation, transformation, and stabilization of the two components were described. The article reviewed current research progresses on the response of soil particulate and mineral-associated organic carbon to climate warming and their influencing factors. On this basis, the shortcomings of existing research and future challenges were discussed, and the key scientific issues that need to be solved urgently at present and future research directions were proposed, in order to provide a theoretical reference for the formulation of soil organic carbon management and solutions to climate change.

Urban transportation resilience reflects the ability of the transportation system to maintain its basic functions and structure through its resistance, mitigation, and absorption under extreme conditions, or the ability to restore the original equilibrium or reach a new equilibrium state within a reasonable time and with reasonable cost. Global warming, sea-level rise, and rapid urbanization all increase the risk of compound extreme weather events, presenting challenges for the operation of urban-related infrastructure including transportation infrastructure. In this context, some questions become important. For example, how to measure the strength of urban transportation resilience under extreme weather events (including the impact of different extreme weather event intensities on its strength); how to monitor its spatial and temporal features and evolution trends; and how long will it take for the entire system to restore balance? At present, effective monitoring methods for transportation resilience under the influence of extreme events are lacking, especially the monitoring of the temporal and spatial dynamic changes of transportation resilience under climate change, to answer these questions. Therefore, it is urgently needed to solve the problem of accurately identifying the state of urban transportation resilience under extreme weather events and improving the level of prevention and control of transportation system impact of natural hazard-related disasters. The development of big data mining technology and deep learning methods for spatiotemporal prediction made the construction of spatiotemporal datasets for evaluating and predicting urban transportation resilience possible. Such datasets can reveal the spatiotemporal evolution features, changing trends of urban transportation resilience intensity under the influence of extreme weather events, as well as the mechanism of influence. It indicates the key research areas that should be focused on for transportation resilience under climate warming. This article reviewed and summarized the research on transportation resilience in China and internationally in the past 50 years, analyzed the deficiencies in the existing research based on the relevant research results of transportation resilience in China and globally, and identified the key areas and directions of the research on transportation resilience under climate warming in order to provide new ideas for future research on transportation resilience.

With the rapid development of tourism and the implementation of the rural revitalization strategy, the relationship between tourism development and the realization of rural revitalization has received increasing attention. Encouraging rural residents to participate in governance in an orderly manner is an important issue for rural revitalization in the new era. Rural tourism can break spatial isolation and reconstruct the rural society, while rural residents' concepts and behaviors are profoundly shaped by their social networks. Therefore how tourism drives residents' participation in rural governance from the perspective of social network reconstruction deserves in-depth study. Based on the social embeddedness theory, this study explored whether the path of "developing rural tourism-restructuring rural social network-promoting residents' participation in rural governance" is valid and its mechanism through two progressive studies. The study found that: 1) The development of tourism can enhance the scale and heterogeneity of the rural kinship-geographic-industrial network and the network position of rural residents, increase the communication frequency and trust intensity of residents in the network, promote information sharing, and reconstruct the rural social network from the dimensions of structure and relationship. Social network affects residents' level of participation in rural governance from the four channels of information acquisition, collective supervision, role model guidance, and community consciousness. 2) The rural governance participation level of residents who participate in tourism operation is strongly promoted by industrial and geographic networks, and the rural governance participation level of residents who do not participate in tourism operation is strongly influenced by geographic and kinship networks. 3) Resident participation in rural governance activities are characterized by participation in cultural issues > participation in environmental protection > participation in political issues > participation in economic development > participation in social services.

At present, the regional spatial system of traditional villages is hollowing out, and the integration of living-production-ecological system, as a good state of regional spatial system development, can be used as a guiding goal to solve the problem of hollowing out the countryside. Exploring the driving factors and processes of typical traditional tourism-driven villages to achieve the integration of living-production-ecological system can provide a reference for the governance of traditional village hollowing out. In this study, we defined the concept of tourism-driven traditional villages' living-production-ecological system integration from the perspective of theory of practice. We took Dehang Village in Hunan Province as an example, decomposed the relevant variables that affect the traditional villages' living-production-ecological system integration relying on the theory of rootedness, and then constructed the motivation mechanism of the tourism-driven traditional villages' living-production-ecological system integration by using the method of system dynamics. The conclusions are as follows: 1) The ecological subsystem is the fundamental basis for the integration of the living-production-ecological system and consists of two circuits: humanized ecological practices and primitive ecological practices. 2) The production subsystem is the material driving force for the integration, including the three circuits of tourism industry development, tourism industry innovation, and tourism production resistance. 3) The subsystem of living is the key guarantee for the integration and consists of three circuits, namely, the practice of material life, the practice of spiritual life, and the construction of political life. 4) Ecological protection restricts the disorderly expansion of production and living, ecological product creation promotes tourism industry development and improves residents' lives, and residents' living practices in turn counter-promote tourism production innovation and ecological protection, with the three subsystems interacting with each other, and superimposing their functions. Summarizing the system dynamics of Dehang Village's spatial system to achieve the integration of living-production-ecological system under the cycle of multiple causal bonds and causal loops can provide a reference for traditional villages of the same type.

The digital economy is a new driving force for the high-quality development of the tourism industry in the new era. In recent years, with the emergence of blockchain, artificial intelligence, Internet of Things, and other emerging technologies, scientific and technological achievements have been rapidly transformed and put into production. Digital technology has become an important force to promote the restructuring of production factors, the improvement of production efficiency, and the optimization and upgrading of industrial structure. The deep integration of tourism—as a tertiary sector of the economy—and digital technology has become the key factor in promoting the upgrading of tourism industry structure. The digital economy, with its powerful productivity and high knowledge intensive form, reshapes the production mode of the tourism industry, improves its efficiency, and injects new momentum into the high-quality development of the tourism industry. However, there is a lack of theoretical exploration and empirical testing of the relationship between the digital economy and the high-quality development of the tourism industry. On the basis of analyzing the role of the digital economy in the high-quality development of the tourism industry, this study constructed an indicator system to measure the level of digital economy development and high-quality development of the tourism industry in 280 cities at the prefecture level and above in China from 2011 to 2019, and used the spatial Durbin model to empirically test the impact of the digital economy on the high-quality development of the tourism industry and its spatial spillover effects. The results show that the digital economy had a direct impact on the high-quality development of the tourism industry, and there was an inverted U-shaped nonlinear relationship. This result is still significantly valid after a series of robustness tests. Further analysis indicates that the digital economy had a spatial spillover effect on the high-quality development of tourism in neighboring regions, and a U-shaped nonlinear relationship existed. The results offer a new perspective for analyzing the impact of the digital economy on the high-quality development of the tourism industry, and provide theoretical reference and empirical evidence for leveraging the digital economy to support the high-quality development of the tourism industry.

The once-in-a-century revolution in the automobile manufacturing industry has triggered a "car-making frenzy" in China, subsequently reshaping the spatial landscape of the country's automobile manufacturing industry. This study used comprehensive micro-enterprise databases and employed location quotient indicators to compare the spatial agglomeration characteristics of the Chinese automobile manufacturing industry between 2013 and 2021. It examined the distinctive location traits of both new energy and traditional automobile manufacturing sectors, while also evaluating the co-agglomeration patterns of three pivotal industries—automobile, electronics, and electrical-in Chinese cities. Additionally, the study employed the negative binomial regression method to investigate the factors that influence the site selection of Chinese automobile manufacturing enterprises. The findings of this study are as follows: Chinese automobile manufacturing enterprises tend to concentrate in cities with a solid historical industrial foundation, showcasing a blend of continuity and change in the industrial layout. The location choices of Chinese new energy automobile manufacturing enterprises are both path dependence and path breakthrough. While cities with established prowess in traditional automobile manufacturing still hold potential for developing the new energy automobile sector, cities with weaker traditional automobile manufacturing sectors, such as Shenzhen, have made remarkable strides in the realm of new energy vehicles. In 2021, only 11 cities in China, including Shanghai, Hefei, and Suzhou, achieved the co-agglomeration of the three major manufacturing industries (automobile, electronics, and electrical). Notably, cities with well-developed automobile industries, such as Chongqing, did not gain specialized advantages in the electronics and electrical manufacturing sectors. Factors such as the diversification index of the manufacturing industry, the complexity of manufacturing knowledge, the size of the resident population, and the location quotient of the automobile manufacturing industry contribute to attracting automobile manufacturing enterprises. Traditional automobile manufacturing tends to gravitate towards cities with a concentration of foreign industrial enterprises, which diverges from the agglomeration patterns observed in the electronics manufacturing sector. The impact of location quotient in the electronics and electrical manufacturing industry on the site selection of Chinese new energy vehicle manufacturing enterprises did not demonstrate statistical significance. This study contributes to enriching the theory of industrial location in China and provides valuable insights for automotive manufacturing companies in their site selection process, as well as informing government policies related to industrial layout planning.

Analyzing the relationship and interaction between economic activities and the environment is a necessary way to achieve human-environment harmony. Environmental economic geography (EEG) emerged at the historic moment, mainly studying the impact of environmental factors on economic activities, as well as the feedback, adaptation, and transformation of economic activities to natural conditions. This article first reviewed the evolution of the discipline of EEG, constructed a research framework from the perspective of economic cycle, and found that EEG research revealed a transition from the focus on external development to the internalization of costs. Through a bibliometric analysis of Chinese and international economic-environmental literature from 1996 to 2023, the article summarized key stages in the development of EEG research, including the initial period, the construction period, and the rapid development period. Combining global value chains and material flow theory, the study analyzed the globalization, relational, institutionalization and evolutionary turn of EEG research topics. In the future, EEG research will be helpful to addressing ecological environmental governance, green innovation and industrial transformation, energy, resilience, and sustainability problems.

Amidst economic globalization, commerce and trade have become increasingly interwoven with national security and foreign policy, emphasizing the growing interdependence of commerce, trade, and foreign policy in the 21st century. This trend has intensified in the 21st century, with the rise of multipolar economies and growing trade and technology conflicts, particularly between China and the United States, fueling interest in geoeconomic research. However, geoeconomic studies still lack clear theoretical and conceptual definitions as well as a complete qualitative analytical framework, posing challenges in supporting China's peaceful rise with a theoretical perspective. This study reviewed the current landscape of Western geoeconomic research, uncovering that: 1) the theoretical development of Western geoeconomics has evolved through two phases: germination and initiation; 2) three predominant schools have emerged: geostrategy, economic geography, and critical geography; 3) geoeconomics and geopolitics are deeply intertwined, rooted in "capitalistic logic" and "territorial logic", respectively; 4) extant empirical research spans various topics, including geoeconomic strategies, the application and impact of geoeconomic tools, and the discourse and conceptualization of geoeconomics. Finally, this article pointed out that geoeconomics is a tangible reality and represents a form of political geography driven by capitalistic logic, focusing on geopolitical spatial economics. It is dialectically integrated with geopolitics, serving both as a diplomatic policy practice and an analytical framework. Based on the coupling of existing research and China's contemporary context, this article suggests that future research in China should address geoeconomic resilience, the implementation and effectiveness of geoeconomic tools at varying scales, geoeconomic practices in smaller countries and third countries, geoeconomics from the perspective of urban regionalism, and the interplay between geoeconomic discourses and practices, to advance geoeconomic theories in China. This research is helpful to accurately and comprehensively understanding geoeconomics, grasping the development trends of Western geoeconomics, and better guiding the development of geoeconomics in China, so as to serve the implementation of "the Belt and rRoad Initiative" and the peaceful rise of China.

Through the exploration of positivism, structuralism, and humanism, the methodology of modern human geography research gradually became systematic and complete. This study, based on the Chinese and international literature on rural settlement landscape and renowned geography scholars' arguments, and referring to the modern human geography philosophical thoughts and their derivative methodology and epistemology, concluded that under the guidance of positivism, structuralism, and humanism, the schools of rural settlement landscape studies followed the renewal path of "tradition-criticism-integration-transcendence". Furthermore, the positivism geography mainly underlines spatiality and regionality, which is summarized as spatialized description of order characteristics; The humanism geography is knee to rediscover the place and symbolic meaning of rural settlement landscapes, with diversified people-oriented humanistic care; The structuralism geography pays more attention to the power and social relationships behind the landscape, and its causality interpretation of the power game. In general, the relevant achievements of research of geographical schools on rural settlement landscape are more microscopic than macroscopic, more static than dynamic, and more material space oriented than socioeconomic space oriented, which have their own strengths and weaknesses in guiding the practice of rural revitalization in China. In the future, a Chinese paradigm of rural settlement landscape research with Chinese characteristics should be created from the perspective of human geography methodology, focusing on the settlement landscapes of different types of rural areas to strengthen the deficiencies of various research paradigms, and develop towards the theoretical integration of positivism, humanism, and structuralism to promote rural revitalization from the perspective of geography.

Innovation is an important driving force for regional development. Since the 1980s, scholars in geography and related disciplines have paid great attention to the relationship between innovation and regional development, and have carried out a wealth of research on regional innovation. In the early stage, regional innovation research took regional innovation system as the main research approach and explored the spatial aggregation mechanism and regional characteristics of innovation activities. In the 21st century, however, with the deepening of economic globalization and the prominence of global challenges in the fields of climate, environment, and energy, regional innovation research has shown a diversified trend in theory and research objects. Although scholars have theoretically reviewed regional innovation research, they have not paid sufficient attention to the changes in the socioeconomic background and theories of regional innovation research. To fill this gap, this article comprehensively comprehended the socioeconomic background, research propositions, and main research topics of regional innovation research paradigm change since the 1980s, revealing the evolution of regional innovation research that shifted from closed to open region precondition and from static to dynamic and transformative analysis, indicating the contribution of other perspectives such as technological innovation system, evolutionary economic geography, and transition studies, and suggesting the importance of global knowledge and the normative turn in regional innovation research. Moreover, after summarizing the current progress, this article proposed that future regional innovation research needs to pay more attention to multi-scalar and comparative regional innovation research and focus on the negative side and the role of the state in regional innovation activities.

The utilization of the resources and environment and the impact on the Earth system of modern human activities have been undergoing great changes. The environment and sustainable development of human society are facing severe challenges. The study of human-earth system coupling provides integrated approaches for solving ecological and socioeconomic problems. However, the understanding of the rural human-earth system coupling is insufficient. Therefore, reviewing the progress of research on rural human-earth system coupling is of great significance for promoting the development of human-earth system science and supporting the decision making for coordinated and sustainable development. The results of this study show that rural human-earth system coupling is a comprehensive process of interaction and mutual influence between the rural socioeconomic system and the natural ecosystem, forming a theoretical paradigm of "process-mechanism-pattern-effect-regulation". The research themes mainly include five aspects, namely, the process and pattern of rural natural and social elements coupling, the influence and feedback of climate change on agricultural production, the driving mechanism of urbanization on rural development, the telecoupling effect of globalization and agricultural trade, and the regulation effects of policy intervention and engineering measures. The research methods mainly involve the coupling evaluation models and the coupling mechanism models. Given the insufficient research on the mutual feedback and transmission mechanisms of rural human-earth system coupling at multiple scales and the lack of data models, future studies should focus on detecting the coupling process and pattern of rural human-earth system under structure transformation and scale extension, analyzing the coupling mechanism of rural human-earth system under elements flow and effects cascade, exploring the simulation and decision-making methods of rural human-earth system that are data-driven and characterized by model integration, and finding the coordination pathways of rural human-earth system under the objective of harmony between humans and nature and global sustainable development.

Culture and tourism are important means to implement the strategy of rural revitalization and play a significant role in promoting the high-quality development and common prosperity of rural areas of China. This study analyzed 933 Chinese publications and 71 English publications retrieved from the CNKI and Web of Science databases, and used the CiteSpace software to analyze the overall situation of the research and hotspots of rural revitalization research from the perspective of culture and tourism. The results show that the research on rural revitalization from the perspective of culture and tourism in China has significant policy-oriented characteristics, and the research intensity has increased year by year. Existing research has proposed hotspots, such as rural cultural and tourism resources and landscapes, rural cultural and tourism integration, rural cultural and tourism enrichment, rural industrial development and integration, rural ecotourism, and cultural and tourism rural governance, combining with the goal of implementing the rural revitalization strategy. Although the research content is relatively rich, there is a lack of further exploration. The research methods are mainly qualitative, and the percentage of quantitative research is low. The study areas are relatively dispersed, mainly concentrated in the southwestern area, at various scales including village, township, county, and province. Finally, this review combined the contents of existing literature and proposed that future research should be innovative in terms of theory, research content, research methods, and study areas, in order to promote the integrated development of rural culture and tourism, provide references for subsequent research, and comprehensively promote the implementation of the rural revitalization strategy.

The widespread trend of suburbanization has resulted in the merging of residential and production elements in suburban areas, causing a significant increase in suburban lifestyles globally. The unique socio-economic and cultural settings of major economies like China and the United States exemplify the distinct features of suburban lifestyle development. An in-depth study of the evolutionary characteristics of suburban living spaces and lifestyles in the two countries benefits the dialogue between Chinese and Western suburban theories. A comparative study can offer valuable references for urban planning in China. This study examined the changes in how suburban living spaces are organized and how people live in them in China and the United States. It took a perspective of the daily lives of suburban residents to compare and analyze these developments. Based on the literature review, this study compared the residential, travel, and activity patterns of suburban residents in China and the United States, and examined how they relate to suburban space. It analyzed how residents' lifestyles have changed in suburban development in both countries and their impact on the suburban area. This article summarized the unique characteristics of suburban living in China and the United States, as well as the mechanisms behind them. Research has shown that both Chinese and American suburban lifestyles follow a three-stage development pattern, starting from monocentric urban lifestyles and eventually transitioning to suburban lifestyles. The suburban lifestyle in China started later, but it has experienced remarkable growth and evolution. The suburban lifestyle is now marked by a diversity of people, mixed residential areas, commuting towards the center, using public transportation, and relying on urban center for daily activities. Living in the suburbs has become a well-established and diverse way of life in the United States. It involves a mix of different populations, residential segregation, commuting inside suburban areas, using motorized mode of transportation for travel, and conducting daily activities in suburban areas. Residential diversification and motorized travel are common aspects of suburban lifestyle that China and the United States share. However, there is a difference in the level of residential integration, motorization, and suburbanization in daily activities between the two countries. Differences in suburban lifestyle between the two countries can be attributed to various factors, including the level of urbanization, transportation infrastructure, and disparities in spatial quality. These differences arise from a combination of choices made by individual residents and external limitations.

The Coupled Model Intercomparison Project (CMIP) has developed rapidly from establishing in the mid-1990s, which provides irreplaceable data support for global climate change simulation and future climate change projection. This paper reviewed systematically the development process from CMIP1 to CMIP6, including theoretical framework, future scenario construction, international participation, etc. On this basis, the paper comprehensively summarized the performance of CMIP models in simulating global and China's temperature, precipitation, and other variables. Furthermore, the simulation results of historical experiment in CMIP3, CMIP5 and CMIP6 was emphatically compared. With the development of CMIP, the simulation performance of global climate models has also been improved due to the improvements of physical parameterization scheme and spatial resolution. However, the performances of CMIP models in simulating climate characteristics at regional scale are still limited, especially for the simulations of precipitation change in small-middle scale, and the simulation performances of different models varies greatly. Finally, the paper looks forward to the possible development directions of CMIP models according to the above problems.

Overseas agricultural industry parks are an innovative way of China's overseas investment, and land use is one of the core issues in its development. Agricultural industry park A is a national-level overseas industrial park that has passed the assessment of the Ministry of Commerce. Its land use and cooperative planting model have important reference value for other overseas parks and the high-quality development of the Belt and Road region. Using interviews, field research, and evolutionary game methods and taking agricultural industry park A as an example, this study conducted a game analysis on the behavioral motivations of park and local farmers in the process of land acquisition, and explored the optimal land use model of overseas agricultural industry parks. The research found that: 1) Plantations have a large demand for land, high investment cost, long payback cycle, and high risk and sensitivity of investment. 2) Park A has formed a development model of "multiple plantations in one park, cooperative development, and construction of the whole industrial chain". 3) Land acquisition game between the park and the local farmers and the Indonesian government's special policies for plantations combined to form a cooperative planting land use model of 80% self-operated land and 20% jointly-operated land. 4) Land acquisition in Indonesia is difficult and affected by many factors, such as private land ownership, difficulties in determining land ownership, and Western neo-colonialism public opinion. The development experience of park A in the exploration of overseas land investment has certain reference value for the land acquisition and use of Chinese agricultural industry parks in other countries with private ownership of land.

Traditional villages is an important spatial carrier of Chinese traditional culture. It is vital for traditional villages to highlight outstanding traditional culture under new urbanization. Taking the Huangdu Dong Cultural Village as an example, this study analyzed the process and mechanism of the spatial production of landscape symbols by participatory observation and in-depth interviews based on the concept of landscape symbol, the theory of landscape gene, and the framework of spatial production analysis. The results show that: 1) Landscape genes identify the overall cultural features from multiple principles and multiple levels, and are also the process of induction and extraction of landscape symbols of traditional villages. 2) Huangdu Dong Cultural Village has transformed from a traditional farming village to a traditional village integrating culture and tourism through spatial coding, landscape restoration, and shaping of cultural, then constructed landscape symbols that meet the needs of multiple actors in terms of landscape, art, life, and location to realize the emotional connection and interaction of landscape symbols and the symbolization of landscape. 3) The promotional mechanism of tourism industrial development in Huangdu Dong Cultural Village connects the internal and external driving forces including resident cultural consciousness, tourism market demand, and government policy support to landscape symbol spatial production, then realizes the integration of modern multi-life demand functions and Dong folk culture, also promotes the spatial production of landscape symbols. Aiming for the activation and sustainable development of traditional villages, this study explored the process and mechanism of landscape symbol spatial production in order to provide scientific and practical references for the creative transformation and innovative development of Chinese traditional culture.
