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.

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.

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.

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.

High-quality cultivation of specialized and sophisticated enterprises that produce new and unique products is an important starting point for consolidating the security foundation of China's industrial chain and supply chain. Using buffer zone analysis and the multi-scale geographically weighted regression (MGWR) model, this study explored the spatial distribution of specialized and sophisticated enterprises that produce new and unique products in the Yangtze River Delta region and influencing factors in 2021. The study found that: 1) Spatially, Shanghai is the main area where specialized and sophisticated enterprises that produce new and unique products are concentrated, followed by provincial capitals and cities on the coast and along rivers; The overall composition of the industry is unbalanced, and the real economic industries such as machinery and equipment manufacturing and high-tech manufacturing account for a relatively high proportion, but there are differences in different regions. 2) In terms of spatial agglomeration, differences between circles and the scale effect are obvious. Within each province, the spatial distribution of specialized and sophisticated enterprises that produce new and unique products in different cities is uneven. Region-wide, the overall spatial distribution pattern of "one pole and multiple cores" is evident. Shanghai is the main agglomeration area for these enterprises, and the provincial capital cities and cities that are the regional economic centers are the secondary agglomeration areas of these enterprises. 3) The four dimensions of influencing factors—physical geography, government, market, and society—have a scale effect on the spatial distribution of specialized and sophisticated enterprises that produce new and unique products. The degree of land development acts at a small scale, which is a local variable, and shows a large difference in the impact on the spatial distribution of these enterprises across the region. Factors such as elevation, government-business relationship, degree of marketization, number and scale of enterprises, degree of openness, logistics development level, and innovation environment are global variables, and except that the degree of marketization and the number of enterprises have a significant negative impact on the spatial distribution of these enterprises, the impact of all other factors is significantly positive. The research results can provide support for the optimization of the layout of new special expertise enterprise space in the Yangtze River Delta region, in order to provide reference for the formulation of new special expertise policies and industrial planning.

The escalating climate and environmental changes in the Arctic have a series of impacts on the local society and economy. Understanding these impacts from the perspective of the tertiary sector can provide references for the sustainable development of the Arctic and globally, as well as for the participation of non-Arctic countries in Arctic affairs. This study systematically reviewed the literature to identify the pathways and effects of Arctic changes on typical industries within the tertiary sector. The results show that various Arctic changes, such as rising temperatures, increasing precipitation, ice melting, and permafrost degradation, have widely influenced the tertiary sector through multiple pathways, presenting both benefits and challenges for most elements of the industries. These impacts offer several insights for relevant studies and for China. Further research is needed to: 1) address the knowledge gaps regarding the pathways of impacts and comprehensively integrate the beneficial and harmful effects of Arctic changes; 2) explore the indirect and cascading impacts of Arctic changes; and 3) integrate multi-source data for research. China can take advantage of the opportunities presented by the changes in the Arctic tertiary sector by: 1) increasing its participation in Arctic rule-making; 2) improving transportation infrastructure and security of the "Polar Silk Road"; and 3) diversifying Arctic tourism products and creating conditions for trade growth.

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.

Geographical sciences is a discipline that study natural and human phenomenon on the Earth's surface and their interrelationships. As an important component of geographical sciences, disaster geography focuses mainly on the spatial distribution characteristics, disaster-prone environments, and occurrence processes of natural hazards and disasters, providing support for the development of scientific disaster prevention and mitigation strategies. With the continuous deepening of disaster geography research and the gradual strengthening of research teams, the National Natural Science Foundation of China established the secondary application code "Environmental Geography and Disaster Geography" (D0104) for the first time under the discipline of geographical sciences (D01) in 2021. Based on this development, this article summarized the connotation and characteristics of disaster geography, and analyzed the application and funding status of disaster geography-related general projects, young scientist projects, and regional science foundation projects over the past two years. It also discussed the 11 research directions included in disaster geography in conjunction with keywords. The results show that: 1) The establishment of the disaster geography sub-discipline code has optimized the application and funding channels for this discipline, and the number of applications has significantly increased. 2) Disaster geography applications exhibit clustering characteristics, and the scientific problem attributes align with the "demand-driven, breaking through bottleneck" principle, but the attributes are relatively singular. Research capacity is concentrated in the North China region, with the Chinese Academy of Sciences as the main research group. 3) Disaster geography mainly focuses on climate change and related hazards and disasters such as flash floods and debris flows. The types of disasters are relatively singular, and the keyword database needs to be updated and optimized in a timely manner. Research methods and techniques in the discipline are relatively diverse. 4) The coverage of sub-directions of research in disaster geography has been preliminarily clarified, and the majority of applications are in the direction of "disaster risk analysis and management". In summary, disaster geography should enrich the attributes of scientific problems, strengthen the breadth and depth of research content, improve the matching between research directions and project applications based on the construction of research teams with regional characteristics, and promote the development of disaster geography, thereby contributing to the construction of an ecological civilization.

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.

Seasonal cycle is the crucial intraannual climate pattern to be observed in global and regional agricultural practice. Under global warming, the global surface has witnessed a significant increase in temperature over nearly half a century. As a result, various parameters associated with surface air temperatures, such as the lengths, start dates, and end dates of the four seasons, also changed dramatically. This study examined the following aspects: 1) It summarized the three types of season definition methods, including astronomical, meteorological, and phenological methods; absolute and relative temperature threshold methods; and other methods characterized by regional geographic factors and specific weather phenomena. 2) This study conducted an analysis on the long-term seasonal variation characteristics in the lower-middle reaches of the Yangtze River and the South China region during 1961-2015, using different seasonal division methods based on air temperature and analyzing the characteristics and differences in summer length calculated by different temperature indices. It also reviewed the characteristics of seasonal length changes in historical periods defined by different indicators and the future projected trends, and summarized the key reasons for seasonal length changes. 3) This study evaluated the advantages and disadvantages of each seasonal division method from their fields of application and spatial applicability. Future research is prospected from the possible impact of data bias, the development of a commonly applicable index, and the mechanism of change under climate warming. The results of this study have clarified the differences of seasonal division methods, as well as the characteristics and causes of seasonal changes. This not only is beneficial for guiding agricultural production, but also provides reliable scientific information for addressing the climate change issue.

Tourism destination loyalty is an effective perspective for studying changes in tourist sources of tourism destinations. In order to enhance the effectiveness of the concept of loyalty, this study took Zibo as an example and used interview and text analysis methods to examine the causes and consequences of the "rushing to Zibo for barbecue" event, and deduced and analyzed the loyalty of tourists and local residents to Zibo barbecue over three time periods from the perspective of scales. The main conclusions of this study are as follows: 1) Loyalty analysis from the perspective of scales can comprehensively analyze the reasons and possibilities of multiple subjects' loyalty attitudes and behaviors from the dimensions of local industrial structure, policy and governance, and cultural symbols, among others. 2) This research explored the scale practice affected by social media attention, and explore how the local government in Zibo and the media at all levels, resorting to social media attention, scaled up Zibo barbecue to a cultural label, and how the tourists and local residents downscaled the kindness in human nature to a multi-dimensional consumption experience in the city. 3) In terms of policy recommendations, the study suggests that local governments maintain brand popularity through festivals every year, but it is necessary to make tourists feel the characteristics of festival carnival without hierarchy, norms, and constraints. During the festival, cultural exchange activities between college students, relevant enterprises, and local public institutions can be added to enhance the possibility of tourists entering Zibo. This study combined the concepts of scale transformation and tourism loyalty to build an academic analysis framework, providing recommendations for improving the sustainability of tourist sources under the impact of the "Internet celebrity" phenomenon.

Promoting the high-quality development of the Liaoning coastal economic belt is of great significance for the development of Liaoning Province, the revitalization of Northeast China, and the regional cooperation in Northeast Asia. On the basis of clarifying the connotation of high-quality development, this study constructed an evaluation indicator system of high-quality development, and used the entropy weight TOPSIS method to measure the high-quality development level of the Liaoning coastal economic belt from 2006 to 2020. Furthermore, using the improved gravity model, this study explored the spatial connection structure of high-quality development and the division method of gravity pattern, and combined the Wilson model to measure the radiation range of cities with radiation capacity. The results show that: 1) During the study period, the high-quality development level of the Liaoning coastal economic belt showed a slightly fluctuating upward trend, and the spatial difference of development level was significant. 2) The driving factors of the development of each dimension were coordinated development, deepening of reform, and green development. Innovation development, kinetic energy conversion, and shared development showed a spatial differentiation led by Dalian City; green development and coordinated development showed a spatial differentiation of leading development in the Bohai Wing; and opening-up and deepening reform showed a spatial differentiation of leading development in the Yellow Sea Wing. 3) The complexity of the spatial connection network structure is increasing year by year, but it is still necessary to further innovate the coordinated and interactive development mechanism of the three major regions of Liaoning coastal economic belt, Shenyang economic zone, and Northwest Liaoning, to improve the level of urban spatial connection. 4) The Liaoning coastal economic belt presents three types of urban spatial connection structure: external radiation type, external dependence type, and balanced radiation and dependence type. Dalian is the only external radiation city, and the spatial radiation range also shows an outward expansion trend.

In the process of rapid urbanization, the imbalance of human-environment relationship caused by the emigration of rural population has exacerbated the problem of rural hollowing out. It is of great practical significance to measure the hollowing out of the countryside and put forward strategies to rectify the problem by focusing on rural revitalization. Taking Baiquan County of Heilongjiang Province as an example, this study used population transfer rate to measure the hollowing level of villages and used the entropy weight TOPSIS method to evaluate the development potential of villages. Combining these two methods, this study identified the type of village development and put forward the differential remediation strategies of hollowing villages. The results show that: 1) Baiquan County's rural hollowing level is 0.6529, and the degree of hollowing is severe. The hollowing at the township level is moderate and high, and the villages are dominated by high and heavy hollowing. Rural population loss is mainly due to the uneven development of urban and rural areas, few rural employment opportunities, low level of rural social security, among other factors. 2) The average development potential of villages in Baiquan County is 0.2279, the overall level is low, and the spatial distribution difference is significant. The development potential of villages around the county seat and along the main transportation routes and major rivers is generally higher than the villages in remote areas. The level of industrial development (0.5026) is significantly higher than that of civilization (0.2703) and ecological environment (0.1472), and low levels of governance (0.0317) and affluence of residents (0.0482) have become shortcomings of village development potential. 3) Villages of Baiquan County can be divided into four types—I: high potential low hollowing, II: high potential high hollowing, III: low potential low hollowing, and IV: low potential high hollowing. Overall the county is dominated by high potential high hollowing, and the development of southern villages is better than the rest of the county. In the future, village development should be guided by the rural revitalization strategies, with a shift of focus towards categories I and II, as well as southern villages and towns. The villages should improve homesteads, ecological land, cultivated land, and other related systems to promote their internal structure adjustment; cultivate cooperatives, family farms, and other new types of management, so as to explore the planning and upgrading of characteristic industries; build a new system of "central town-central village-rural community-village" to enhance urban-rural interaction and promote factor aggregation and resource sharing; and increase environmental regulation, enhance social security, and attract the return of talents, thus realizing village hollowing governance and rural revitalization in the county.

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.

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.

The global development of the Internet and mobile communication technology has greatly expanded individuals' access to and occupation of space and social resources. In the interaction and integration of cyberspace and real space, cyberspace has been interpreted in geographical and sociological dimensions, and the conceptual connotation has shifted from technology to space, society, and media. New technologies create new problems. Geographers have discussed the impact of the Internet and other information technologies on individual activities, urban space, and social development. However, there is still a lack of research on geographical concepts and geographic characteristics in cyberspace, which has become an obstacle to the development of geography of cyberspace. This study focused on the research of cyberspace in the field of social geography, used bibliometric methods to identify the research hotspots of scholars in China and internationally in the field of cyberspace geography in different periods, examined the development of cyberspace and its social-spatial attribute construction process, and based on the perspective of virtual-real hybrid space, summarized the progress of the social geographical research on cyberspace from the aspects of line decay, media space and virtual representation. This review aims to enhance understanding and exploration of geographic phenomena and social issues in cyberspace, and to advance the field of cyberspace geography.

Non-grain cultivated land is the key area of cultivated land supplementary source and use control. Realizing the objective of protecting cultivated land in the new era depends on scientifically determining the potential of non-grain cultivated land consolidation and clarifying the differentiated control strategies. Taking the Chengdu Plain as the study area, this study developed a research framework of "connotation definition-potential identification-differentiated control". Based on a systematic analysis of non-grain cultivated land consolidation potential, the theoretical potential of non-grain cultivated land consolidation was clarified by identifying non-grain cultivated land patches and applying relevant resource and environmental carrying capacity and territorial spatial development suitability evaluation methods. On this basis, an evaluation system for the actual potential of non-grain cultivated land consolidation was constructed, which includes planning and control constraints, farming condition constraints, economic support constraints, and societal willingness constraints. Finally, the two-dimensional graph theory clustering algorithm was used to develop the non-grain cultivated land consolidation zoning, and the control strategies were proposed. The results show that: 1) The agricultural production conditions of non-grain cultivated land on the Chengdu Plain are favorable. The theoretical potential area of non-grain cultivated land consolidation is 2461.14 km², which shows a spatially imbalanced distribution. 2) The coefficients of planning and control constraints, farming condition constraints, economic support constraints, and societal willingness constraints are 0-0.43, 0.25-0.70, 0.18-0.86, and 0.41-0.77, respectively. Correspondingly, the actual potential area of non-grain cultivated land consolidation is 2348.31 km², 1347.89 km², 1676.52 km², and 1292.74 km². There are significant differences in the actual consolidation potential scale driven by multi-factor constraints. 3) Using the "constraint type + timing" method, the non-grain cultivated land consolidation areas on the Chengdu Plain was divided into five zones. The combination of constraint types and consolidation timing arrangement of different zones determines the differentiated non-grain cultivated land consolidation control strategy. The results of this study provides some scientific support for strengthening the governance of cultivated land non-grain use and ensuring the implementation of the "balanced entering and exiting" system of cultivated land on the Chengdu Plain.

As human infrastructure activities are becoming increasingly frequent, the impact of infrastructure activities on human-land relationship and human social-spatial structure has triggered extensive discussions in human geography and other related disciplines. This study systematically discussed the research context and core issues of the feminist infrastructure geography studies. First, this study categorized the research literature on infrastructure in geography and found that the research on infrastructure in geography showed a trend of "social-cultural turn" that emphasizes that infrastructure is not only about its functional attribute, but also has multiple attributes, such as social and cultural ones. Second, from the perspective of feminist geography, this study emphasized the important value of gender and the related core-periphery perspective in the social-cultural turn in infrastructure research and pointed out that feminism can provide an excellent perspective with both micro and macro perspectives for analyzing the spatial effects of infrastructure. Third, based on the different impacts and paths of the heterogeneity of human society reflected in the gender perspective on the transformation and utilization of the environment by using infrastructure, this study outlined the main content of feminist infrastructure research based on the gender perspective from two different fields, namely, the gender difference at the producing end of infrastructure as well as at the using end of infrastructure. Based on such literature, this study finally built a core conceptual framework and analytical framework for feminist infrastructure geography studies. In the end, the developments of feminist infrastructure geography studies presented in this article also provide a good opportunity for an interdisciplinary dialogue on a larger and broader scale by other scholars broadly concerned with feminist topics.

A series of problems caused by rapid urbanization have a negative impact on the mental health of residents. As an essential health intervention, green spaces facilitate resident exposure to the natural environment and relieve mental stress. However, existing studies mainly use cross-sectional data, making it difficult to reveal the causal relationship between green space and mental health. In addition, few studies focused on the differences in the mental health effect of green space among different social groups. Therefore, we used a natural experiment approach to explore the impact of a large-scale greenway intervention—the East Lake Greenway in Wuhan, China—on residents' mental health. We collected data from the health effect questionnaires in 2016 and 2019 (before and after the intervention) among residents living around the greenway, used the difference-in-differences model to explore the causal relationship between green space intervention and residents' mental health changes, and combined stratified analysis to reveal differences in the causal effect of green space on mental health across various social groups. The results show that: 1) The green space intervention significantly promoted the improvement of mental health for the experimental group. 2) The causal effect of green space intervention on residents' mental health was not significantly different among groups with different gender and education levels, but there were significant differences among groups with different occupations and income levels, indicating that the greenspace intervention has significantly improved the mental health of the unemployed, low-income, and low-middle income groups. Overall, the construction of large green spaces can effectively improve the mental health of surrounding residents, especially for disadvantaged groups such as the unemployed and low-income groups. Green space interventions are critical for improving the mental health of residents and alleviating inequalities in mental health benefits due to differences in socioeconomic status.

Rurality in the context of tourism is not only the epistemology of rural grand narrative, but also the methodology leading the practice of rural tourism development. This study analyzed the rural development process from traditional villages, rapid urbanization, to urban-rural integration, reviewed the relevant literature on rurality in China and internationally from the perspectives of rural regional functions, political economy, and overall rural construction, and analyzed rurality in the context of tourism based on the conceptual analysis logic of "element composition-basic attributes-important features". This study proposed that: Rurality in the context of tourism is the local significance of tourism's influence on the human-environment relationship in the process of rural reconstruction. From the perspective of the subjects of demand, it is reflected as tourists' cognition and emotion towards the countryside, and from the perspective of rural development, it is reflected as the result of the practice of rural tourism development carried out continuously by multiple subjects in the context of specific rural regional space. The basic attributes of economy, social and culture, nature and landscape, the regionalism of spatial dimension, the dynamic nature of time dimension, and the experience of value dimension should be understood in the relationship between "I" and "other", urban and rural, modernity and tradition, and commerciality and authenticity. This study constructed a framework of rurality concept analysis in the context of tourism, and put forward the prospect of future research at the levels of research content and methods.

In the context of the digital age, the emergence of information and communication technology (ICT) provides a new space for children's growth. This study collected a total of 89 publications in English related to ICT and children's geography through the Web of Science (WoS) SSCI collection and Google Scholar, and summarized the research connotation of ICT. From a technical perspective, this article summarized the technological changes of ICT in children's daily lives and its research applications in children's geography. By constructing a framework of review of globalization-localization at the macro level, public space-learning space-home space at the meso level, and personal identity construction at the micro level, the relevant research on ICT and children's groups was interpreted from a geographical perspective. Finally, by breaking the independent and closed binary intergenerational boundary in previous studies on children and introducing new debates on real-virtual and private-public, this review broadens research ideas from a new perspective. It also points out that the ways to guide the underage group to fully integrate into the digitalization background in daily life, creatively use digital tools, and view the relationship between themselves and technology in a healthy manner will become a new focus of children's research in the Chinese context, and calls for attention from the academia and social sectors on the development of children in the digital age.
