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.

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.

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.

Understanding the degree of rural tourism gentrification, balancing the relationship between stakeholders such as native rural residents, new rural residents, and returned rural residents, and truly realizing the sharing of development dividends are the key to achieving the comprehensive rural revitalization and rural tourism sustainable development. As one of the important representations of rural space value reshaping, tourism-driven rural gentrification has attracted great attention in the context of rural revitalization. From the perspective of the influencing effect of rural tourism gentrification, this study analyzed the spatial restructuring characteristics of Hanwang Village in different periods of tourism gentrification development based on field research data and spatial interpretation results. Combined with the semi-structured interview data, this study also analyzed the mechanism of spatial restructuring by using the actor-network theory. The results show that: 1) According to the tourism construction and development process, the tourism gentrification process in Hanwang Village can be divided into four stages, including traditional agriculture transformation, sightseeing agriculture exploitation, rural tourism development, and cultural and tourism integration transition. Different stages of spatial restructuring present different characteristics. 2) The process of tourism-driven rural gentrification has successively changed the land use distribution, industrial structure, population composition, and cultural atmosphere of Hanwang Village, and alleviated some of the problems of rural hollowing, which had a profound impact on the village space. 3) The transformation of the interests and goals of heterogeneous actors, such as governments at all levels, village residents, tourists, investors, art practitioners, and tourism resources, as well as the connection and cooperation between them, have an effect on the spatial restructuring of Hanwang Village. This study took Hanwang Village in Xuzhou City as a case study, and mainly focused on the impact of tourism-driven rural gentrification development on rural spatial restructuring, the behavioral logic of various stakeholders in the process of spatial restructuring, and the relationship with rural hollowing, so as to provide theoretical and empirical references for the study of tourism-driven rural revitalization development and rural gentrification effect, and solving the problems of hollow villages.

New quality productive forces are advanced productive forces under the background of new scientific and technological revolution, which meet the requirements of high-quality development. Understanding its connotation and current situation is crucial to accelerating the formation of new quality productive forces and promoting Chinese style modernization. Based on the connotation and practical requirements of the new quality productive forces, this study used the WSR (Wuli-Shili-Renli) system methodology for reference, constructed the evaluation indicator system of the new quality productive forces, and explored the development process and spatiotemporal differentiation characteristics of the new quality productive forces in Chinese cities from 2008 to 2021. The results show that the level of new quality productive forces in China and its four regions presents a significant upward trend, and the intraregional differences are declining. There is a spatial heterogeneity in the level of urban new quality productive forces in China, showing a distribution pattern of "high in the east, medium in the central part, and low in the west and northeast". There are significant differences in the level of urban new quality productive forces at different administrative levels, different population sizes, and different levels of per capita GDP. The level of urban new quality productive forces in China has the characteristics of spatial agglomeration, the local spatial relationships vary little, and the stable hotspots are distributed in Beijing, Shanghai, and Guangzhou. The level of independent innovation and human resources in the eastern and central regions is higher than that in the western and northeastern regions, while the development of digital technologies and emerging industries is significantly better in the eastern region than in other regions. By examining the change in the spatial and temporal patterns of China's urban new quality productive forces level, we hope to provide a decision-making reference for optimizing layout and accelerating development of the new quality productive forces.

In recent years, under the background of a series of national development strategies and the transformation of economic geography patterns, the connections between cities, towns, and rural areas in China have become increasingly close, bringing about a more diversified population distribution than before. However, there are still few studies that simultaneously involve the spatial analysis of cities, towns, and rural areas, as well as the evolution patterns and underlying mechanism of population distribution in regions with different levels of development. Based on the data of the sixth and seventh national censuses (provincial data of Jiangsu Province), this study explored the spatiotemporal evolution of city, town, and rural population distribution and revealed the influencing factors of the comprehensive attraction of city-town-rural areas to the floating population in Jiangsu Province from 2010 to 2020. The results show that: 1) In the past 10 years, Jiangsu Province maintained a population spatial distribution pattern of dense in the south and sparse in the north, but the changes in the size of the resident population and floating population have shown noticeable geographical differences, which is manifested in the continued high growth rate of resident population in south Jiangsu, but the high growth rate of floating population is concentrated in central and north Jiangsu. 2) In the past 10 years, the high-value area of the ratio of floating population to resident population was still concentrated in south Jiangsu. The proportion increased in all cities and some towns in central and north Jiangsu, as well as slightly in some rural areas in south Jiangsu. 3) Comprehensive exploration of changes in the population distribution of the city-town-rural areas has found that although the trend of common growth of resident population in the three types of space was not obvious, the ratio of floating population to resident population in more than half of counties and cities showed the characteristics of city-town-rural area common growth. The increase in the comprehensive index of city-town-rural area attraction to floating population in central and north Jiangsu exceeded that of south Jiangsu. 4) Public affair investment of the government and regional industrial development had a significant positive impact on the comprehensive attraction of city-town-rural areas to floating population, which had a stronger effect in economically developed areas and areas with stronger industrial base. In contrast, advanced industrial structure only had a positive effect in south Jiangsu. Based on the correlation between the change in population distribution and the level of regional urbanization, as well as the analysis of its spatial distribution characteristics and influencing factors in city-town-rural areas, this study put forward specific suggestions for the urban-rural integrated development of the population in different counties and cities.

The diagnosis and identification of farmland marginalization are intricately linked to establishing a delicate equilibrium between food security and ecological security. This study constructed a comprehensive analytical framework of "temporal diagnosis, explicit and implicit factor interaction, and spatial distribution" by categorizing farmland marginalization types and integrating traditional diagnostic concepts. Using Shepeng Village, the birthplace of the "three changes" reform, as a case study, we conducted an investigation into the spatial and temporal distribution and characteristics of different types of arable land employing standard deviation ellipse, 3D kernel density, and other spatial analysis methods. The findings indicate that: 1) The temporal diagnosis of farmland marginalization can be done through the interannual variation of net income as a key indicator and can be manifested spatially by the trend of farmland conversion to other land use types. 2) Between 2000 and 2020, farmland in Shepeng Village displayed two prominent marginalization phenomena, occurring in 2013-2014 and 2016-2017, with the latter being more pronounced. 3) During 2010-2015, farmland marginalization in Shepeng Village exhibited explicit and implicit characteristics prominently. The physical, natural, and economic marginalization of farmland as explicit features amounted to 7.13 hm², 0.99 hm², and 33.27 hm² respectively. The degree of marginalization in implicit features demonstrated more significant changes before and after the "three changes" reform, displaying characteristics of mutual fusion and alternating changes. Policy recommendations centered around the concept of food security, economic development, and ecological protection were proposed to provide guidance for promoting the protection and sustainable use of farmland in mountainous areas.

The integrated development of urban and rural areas is an important measure for achieving comprehensive rural revitalization in China, and policymakers are particularly concerned about this issue. The initial intention of establishing the land bill system in Chongqing Municipality was to promote coordinated and integrated development between urban and rural areas, but there has been a lack of corresponding evaluation. Based on the panel data from 70 cities between 1998 and 2020, land bill transaction data from 2008 to 2020, and a survey of farming households in outflow areas of land bill, this study systematically evaluated the impact of the land bill system in Chongqing Municipality on the integrated development of urban and rural areas through spatial analysis and synthetic control methods. This study found that the land bill system promoted urban-rural integration in Chongqing, manifested by an increase in the per capita disposable income in rural areas, the supply of urban construction land, the supply of the non-agricultural labor force, and regional per capita GDP. The pressures of farmland loss and income disparity between urban and rural residents have significantly decreased. The land bill, as a "lever", couples the elements of people-land-industry-capital in rural areas, which is conducive to building interactive relationships among the internal elements of the urban-rural regional system, and further promotes the integrated development of urban and rural areas. Considering that the land bill system has been piloted in many parts of the country, it is necessary to further explore ways to improve the linkage between collective-operated construction land near cities and the land bill system in remote suburbs, in order to promote the balanced adjustment of urban and rural integrated development. At the same time, the government should actively expand the service functions of the land bill system in rural revitalization and ecological restoration, moderately increase land supply, and restore rural idle land to ecological land, thereby synergistically promoting the development of ecological civilization.

Traditional household travel survey provides the basic data for urban traffic planning and the most authoritative record of urban residents' travel behaviors. With the development of information technology, position data represented by mobile signaling data have shown great potential in the field of temporal-spatial behavior research. However, whether the mobile signaling data can replace the travel survey data is controversial because the travel data accuracy of mobile signaling data is difficult to assess. How credible the identification results are and whether the travel characteristics of residents can be accurately measured remains to be answered. In this study, the travel survey data of Shanghai residents and mobile signaling data with similar dates were used to compare the differences in intensity, time, spatial distribution, purpose, and other characteristics of travels. This study also analyzed the degree of deviation and summarized the causes of errors. The research revealed that the mobile signaling data are more accurate in describing the per capita travel times of the travel population and the travel origin-destination (OD) distribution at the scale above the street, but less accurate in describing the travel time distribution and travel purposes. Our research suggests that the main reasons for the deviation in mobile phone data are the impact of incomplete location records on data quality, the impact of retention time thresholds, spatial thresholds, and home and workplace identification. Due to the above systematic errors, mobile signaling data cannot replace household travel survey data. Nevertheless, the accuracy of mobile signaling data analysis can be improved by sample screening, trip chain data recovery, and improvement of identification methods.

With the continuous improvement of people's living standards and increasing income, household energy consumption has become an important growth point of energy consumption in China. Grasping the spatiotemporal characteristics of household energy consumption and identifying the influencing factors and development trends of household energy consumption will help to accelerate the construction of a modern energy system, promote low-carbon energy transformation, and achieve the dual carbon goals. This study took household energy consumption as the research object and systematically explored its spatiotemporal evolution characteristics in China. Furthermore, it used the spatial econometric models, grey prediction, and scenario analysis to examine the influencing factors and development trends of household energy consumption. The study found that: 1) From the perspective of spatiotemporal characteristics, household energy consumption showed an upward trend from 1995 to 2021. Meanwhile, the gap in energy consumption between urban and rural households was gradually widening, but their per capita household energy consumption showed a trend of convergence. 2) From the perspective of proportion and structure, household energy consumption accounts for about one tenth of the total energy consumption, and the household energy consumption structure showed a trend of diversification and clean development. 3) From the perspective of influencing factors, energy intensity, population size, household size, education level, economic development, urbanization rate, and car ownership were important influencing factors for household energy consumption, but the degree of impact varied. 4) From the perspective of future trends, China's household energy consumption will continue to grow by 2040, and under the scenario of steady development, the growth rate is slower, indicating that the implementation of government policies and the popularization of green consumption concept among residents have a positive effect on controlling the growth of household energy consumption. Based on the results of this research, this article argued that the energy consumption structure should be adjusted by increasing the proportion of natural gas consumption, the energy consumption structure of rural households should be optimized, and the energy development policy should be further improved and the consumption concept of residents should be changed to control the excessive growth of household energy consumption.

In the context of new type urbanization and rural revitalization, multifunctional transformation provides an important path for rural sustainable development. Multifunctional rural development in turn unfolds a powerful entrée into understanding sustainable rural transformation. Employing both quantitative and qualitative approaches, we documented the study hotpots in rural multifunctionality in this review. Foremost, we systematically examined the definition and change of multifunctionality, and collected and analyzed a total of 1385 publications from both the CNKI and WoS databases with the help of the CiteSpace software. This paper provides a panoramic synthesis of the primary research topics related to rural multifunctionality, summarizing current advancements in evaluation measures, evolutionary processes, driving factors, and interactions among various functions, and ultimately delineating prospective research directions for future studies. Overall, The results reveal that the conceptual connotation of rural multifunctionality has been deepening with the transition of rural development from"productivism" to "post-productivism".The research paradigm has also evolved to emphasize interdisciplinary perspectives and the integration of multi-methodological approaches. Future research should further strengthen the integration of scales in assessing rural multifunctionality, the incorporation of diverse evaluation methods, and promote the expansion of social functions assessment, while conducting comparative studies across various regions involving multi-stakeholders. In particular, by summarizing patterns of multifunctional development and transformation under different developmental paths, researchers can extract the transformation and evolution patterns of various types of rural multifunctionality, as well as substantiating pathways for optimizing rural transformation and revitalization under different dominant functions.

In recent years, the rapid expansion of lakes on the Tibetan Plateau has attracted widespread attention, and a number of studies have systematically analyzed the dynamics of changes in large lakes with areas greater than 1 km². However, the distribution and changes of smaller lakes and ponds formed due to permafrost degradation at the watershed scale have not yet been clarified. In this study, using optical and radar images, we systematically investigated the distribution and changes of lakes and ponds (< 1 km²) in the Three Rivers Source Region and their relationship with permafrost degradation, and for the first time examined the distribution of taliks at the bottom of the lakes and ponds. The results show that: 1) The total area of lakes and ponds in the Three Rivers Source Region in the 2020s (2020-2022) amounted to 917.03 km², and the total number of lakes and ponds was 61608. The Yangtze River source area had the highest number of lakes and ponds, reaching 48987, followed by the Yellow River source area with 12459, and the Lancang River source area had the smallest number of lakes and ponds. 2) Compared with the 1960s, the number of lakes and ponds smaller than 1 km² in the Three Rivers Source Region increased by 76% in the 2020s, and the total area increased by 13%. Although the expansion of lakes and ponds in the Yangtze River source area was obvious, some lakes and ponds in the Yellow River source area and the Lancang River source area experienced shrinkage. Of the lakes and ponds observed in the 1960s, 53% still existed in the 2020s. 3) Of the lakes and ponds in the Three Rivers Source Region, 80.9% have taliks at their bottoms in winter, including 78.2% in the Yangtze River source area, 90.8% in the Yellow River source area, and 98.7% in the Lancang River source area. In the permafrost zone, half of the lakes and ponds with taliks at their bottoms existed in the 1960s, and fewer new lakes and ponds have taliks at their bottoms in winter. Currently, the extent of floating-ice lakes and ponds is much larger than the extent of grounded-ice lakes and ponds, which may further accelerate the thawing of the underlying permafrost. The findings of this study can provide a basis for analyzing the state of permafrost degradation and contribute to understanding the links between permafrost degradation and the development of thermokarst lakes and ponds, as well as serve as basic data for the study of carbon emissions from thermokarst lakes and ponds in the plateau region.

An in-depth understanding of the transition of freshwater aquacultural water surfaces is significant for implementing the new development concept and macro view on food and for promoting global sustainable development. However, studies on the structural transition of aquacultural water surfaces and its driving mechanisms are still very limited. As socioeconomic development progresses, there are significant impacts of the growing market demand of freshwater products and water control policies such as the lake chief system on aquacultural water surfaces. Using the Simpson index method, center of gravity model of geographic factors, and panel regression models, we took the Jianghan Plain as an example to reveal the structural transition characteristics of aquacultural water surfaces from the perspectives of type structure and spatial structure by focusing on the mechanisms under the combined effects of market-induced changes and policy control. The results show that: 1) From 2001 to 2020, the freshwater aquacultural water surfaces on the Jianghan Plain experienced a transition from rapid expansion to slow expansion; the type structure experienced a transition of "large water to small water, small water refinement, and comprehensive breeding dominance"; the spatial structure experienced a transition of "large water climbing, small water towards the river". 2) Market-induced type substitution mechanism, that is, the bottom-up market-induced substitution of aquacultural water surface types driven by the pursuit of labor productivity maximization, combined with the policy compulsory structural adjustment mechanism, that is, the top-down water control policy implementation such as the lake chief system, has driven the structural transition of aquacultural water surfaces on the Jianghan Plain. In addition, this article proposed policy recommendations to strengthen the regulation of structural transition of aquacultural water surfaces. This study is important for promoting the expansion of land use transition research to aquacultural water surfaces and deepen the analysis of structural evolution.

With the in-depth development of a new round of scientific and technological revolution and industrial transformation, intelligent manufacturing equipment has become an important force to promote the high-quality development of industry, and the study of its production and supply relationship is of great significance to optimize the distribution of new quality productivity.Based on the data of core enterprises and suppliers in China's intelligent manufacturing equipment industry from 2010 to 2023, this study explored the spatial change characteristics of production-supply relationships of China's intelligent manufacturing equipment industry from three dimensions: production and supply linkage, production and supply network, and production and supply cluster by Pareto analysis and k-kernel analysis. The results are as follows: 1) The number and intensity of enterprise connections were increasing, and 700-1800 km was the general distance of production and supply connection of intelligent manufacturing equipment enterprises. The pattern of intercity production and supply links evolved from the shape of dual core radiation, triangle, to bow and arrow in China, and there were similarities and differences in the dominant flow of intercity production and supply links. The strong production and supply links between enterprises gradually shifted from intracity to intercity, and the number of export-oriented cities increased rapidly. 2) For more than a decade, the structure of the intercity production and supply network of China's intelligent manufacturing equipment industry has become increasingly compact and complex. After 2015, the city hierarchy of the intercity production and supply network has moved from a "pyramid" to a flat structure. 3) The number of production and supply clusters of China's intelligent manufacturing equipment industry has increased from 21 to 29. The production and supply cluster of the Yangtze River Delta has always maintained a leading position, the production and supply clusters of the Pearl River Delta, the Beijing-Tianjin-Hebei region, and Shandong Peninsula have developed steadily, and the status of the production and supply clusters in the middle reaches of the Yangtze River and the Chengdu-Chongqing region have significantly improved. The pattern of association of node cities within the clusters can be divided into five types: Single center, one core and multiple subordinates, two cores and multiple subordinates, multi-center, and low-level equilibrium, and the node association patterns within the clusters have showed spatiotemporal heterogeneity from 2010 to 2023.

Digital empowerment for the deep integration of rural culture and tourism is an important initiative for the upgrading of rural industries and the comprehensive revitalization of the rural areas in the context of the digital economy. Taking Wusi Village in Zhejiang Province as an example, this study applied the actor network theory to explore the process and mechanism of the deep integration of rural culture and tourism based on digital empowerment. The results show that: 1) The deep integration of rural culture and tourism based on digital empowerment in Wusi Village is a dynamic process in which multiple subjects participate and play with each other in three stages: initial exploration, rapid development, and deep integration. In the process of the deep integration of rural culture and tourism based on digital empowerment in Wusi Village, the village committee continues to play a key role, the role of market players such as cultural and tourism enterprise is gradually increasing, and the degree of association of rural residents with the network of actors is gradually deepening. 2) The deep integration of rural culture and tourism based on digital empowerment in Wusi Village is driven by a dynamic circular mechanism consisting of the rural core system and the peripheral system as the integration basis, digital technology and digital platform as the integration support, governmental, societal, and local forces formed by the interaction of multiple actors as the integration actor, and the deep integration of the rural cultural and tourism resources, products, industries, factors, markets, and values as the integration content. 3) The high-level cyclic development of the deep integration of rural culture and tourism based on digital empowerment is the result of the release of strong effects of both the mechanisms of action and reaction of the integration support and integration actor, and that of the integration actor and integration content. This study provides a theoretical basis and empirical experience for the high-quality development of rural digital cultural tourism, the upgrading of rural industries, and comprehensive rural revitalization.

Urban affordable housing communities are often located in suburbs, and these large communities have increasingly become focal points in urban social geography research due to the unique social, economic, and cultural attributes of their residents, the impact of affordable housing communities on residents' employment, lifestyle, and behavioral patterns, as well as the urban social-spatial issues such as residential spatial differentiation and resource distribution disparities induced by the construction of affordable housing. To address the deficiencies in relevant existing studies, including the lack of big data, comprehensive samples, and multi-dimensional, small-scale analyses, this study selected Daishan, the largest affordable housing area in Nanjing City, as the research object. Using 21 residential communities (groups) within the area as spatial units, and utilizing mobile user profiles and questionnaire survey data, combined with social, spatial, behavioral, and perceptual factors, this study investigated the social-spatial characteristics and issues of large affordable housing districts on urban outskirts. The findings reveal that the Daishan area exhibits characteristics such as aggregation of vulnerable groups, insufficient service facilities, heavy commuting burdens, and weak community belonging. While the social space across the area is relatively homogeneous, residents of communities with high concentration of public rental housing have the poorest economic conditions. Conversely, areas with better environmental and residential quality tend to house high-income young professionals. Future development in the area must pay attention to potential risks such as the perpetuation of poverty, community decline, and social discrimination. By integrating big data and conventional data sources to explore social spaces on a fine-grained spatial scale, this approach effectively compensates for the deficiencies of traditional data sources, such as socioeconomic statistics and sample questionnaire survey. This enables a nuanced exploration of urban social-spatial phenomena, providing detailed and authentic insights into the complexities and issues within social spaces.

A meticulous examination of land use transformation processes and mechanisms within typical suburban villages holds profound implications for the successful execution of rural revitalization strategies and the exploration of sustainable developmental paths. In this study, She Village in Jiangning District of Nanjing City was selected as an example, and literature research, participatory rural appraisal, and GIS spatial analysis methods were used to reveal its apparent and latent land use transition processes from a microscopic perspective in 1980-2020. The results illuminate the following key insights: 1) Within She Village, a substantial transformation in the quantitative composition and spatial arrangement of land use has unfolded. Notably, forested areas and arable land have experienced a persistent decline, while commercial, transportation, and public administration/public service land have shown consistent expansion. Industrial and mining land initially exhibited growth but subsequently witnessed contraction. 2) The land in She Village has experienced a multifaceted functional change. It transitioned from primarily an agricultural production base to an industrial production hub, and ultimately evolved into a tourism-centric locale. Simultaneously, the residential function of this land strengthened continually, albeit at the expense of an initial decline in its ecological function. The result is a complex amalgamation of multifunctional and compounded land uses. 3) The observed transformation of She Village's land uses is a product of the interplay among resource endowments, policy frameworks, market dynamics, and key land use stakeholders. Consequently, the village has evolved from its original identity as a space predominantly for livelihoods and production to one predominantly characterized by consumption. Suburban villages surrounding metropolitan areas have gone through three pivotal stages: agricultural development, industrial expansion, and tourism-oriented service growth. This evolution has engendered a deepening diversification of land use categories, intricate functional amalgamations, and a proliferation of diverse business enterprises. It is paramount to comprehend the synergistic influence of top-down governmental initiatives, intrinsic rural dynamics, and the urban sphere's radiating effects on land use patterns. This comprehension will be instrumental in advancing the initiative of new urbanization and promoting urban-rural integration, thoughtfully tailored to the specific conditions of each locality.

Against the backdrop of globalization and informatization, digital transformation is not only crucial for cultural and tourism enterprises to enhance service quality and competitiveness but also an inevitable path to achieving high-quality development. Leveraging the theory of complex network evolutionary games, this study constructed a diffusion model for the digital transformation strategies of cultural and tourism enterprises. It delved into the impact of government subsidies on the digital transformation behavior of these enterprises across different regional economic development levels. The findings underscore the significant role of government subsidies in fostering digital transformation among cultural and tourism enterprises. These subsidies expedited decision-making processes and widened the economic disparity between transformed and non-transformed enterprises. Furthermore, the study revealed that the prosperity of the regional economy shaped the decision-making landscape for cultural and tourism enterprises, with those situated in economically developed regions exhibiting a greater propensity to embrace digital transformation. However, as the regional economy attains a certain threshold, the stimulatory effect of government subsidies may diminish, potentially slowing down the pace of digital transformation. This research offers insights for governments to formulate targeted subsidy policies, while also providing theoretical underpinnings and practical guidance for cultural and tourism enterprises to capitalize on the opportunities presented by digital transformation and attain high-quality development. By bridging the gap between policy formulation and corporate strategy, this study contributes to the advancement of the cultural and tourism industry in the digital age.

Based on the measured precipitation stable isotope data and related meteorological data in Lanzhou City from April 2019 to October 2022, this study used the HYSPLIT backward trajectory model to systematically examine the characteristics of variation of hydrogen and oxygen stable isotopes of precipitation and the difference of isotopes between day and night under different types of precipitation events (convective precipitation, stratiform precipitation), and trace the water vapor sources. The results show that: 1) Both δ²H and δ¹⁸O in precipitation presented a trend of enrichment and then depletion, while d-excess in convective precipitation showed a trend of depletion and then enrichment during the daytime and continuous depletion at night, and d-excess in stratiform precipitation all showed a trend of depletion and then enrichment. 2) The local atmospheric water line slope (8.01) and intercept (15.55) of convective precipitation at night were the largest and closer to the global atmospheric water line, while the local atmospheric water line slope (6.81) and intercept (4.08) of stratiform precipitation during the day were the smallest, indicating that stratiform precipitation was more susceptible to evaporative fractionation. 3) There was a positive correlation between air temperature and δ¹⁸O values, and the influence on the daytime stratiform precipitation isotope was most significant (r=0.59, P<0.01). There was a significant negative correlation between relative humidity and δ¹⁸O values, and the most significant effect was on the isotopic values of convective precipitation at night (r=-0.52, P<0.01). There was no significant correlation between precipitation and precipitation isotope during the day, but a negative correlation at night (r=-0.26, P<0.05). 4) In the summer half year (April to October) in Lanzhou, the precipitation-producing water vapor mainly comes from Central Asia, Mongolia, and other northern regions and is transported to Lanzhou through the control of the westerlies and continental air masses, and only a small part of it is affected by the southwest monsoon. The results of this study can provide a new perspective for exploring the key drivers of precipitation isotope change in arid areas, and have important significance for modern climate research and water resources management.

The development of information and communication technology and the penetration of mobile smart devices enable information dissemination and social interaction to overcome the barriers of geographical distance, greatly expanding the scope and depth of interaction between individuals and space. The fusion of real and virtual spaces has led to a new paradigm of individual behavior patterns and research on cyber-mobility. The study of personal mobilities in both physical and virtual spaces has received growing attention by contemporary scholars in geography, sociology, and economics. This article reviewed the geographical research on cyber-mobility from the geographical societal perspectives by Aharon Kellerman, a professor of human geography at the University of Haifa. Based on advanced research and understanding of the time-space framework of personal mobility and geographical interpretations of cyberspace, Kellerman delved into exploring the ways of personal mobilities and spatiotemporal behavior patterns of individuals in the process of using the internet from the dual perspectives of individual "social people" and "incarnations", and further participated in the research in the fields of human behavior patterns, virtual community, virtual activity space, and so on. His theory and empirical research help Chinese scholars to deepen their understanding of the role of virtual space and network technology from both micro and macro perspectives, and the relationship between real and virtual spaces, and to further explore the interactions between individuals and real space and cyberspace and urban space reconstruction.

In recent years, the cultural economy has become an important means of urban reengineering, reshaping the post-industrial path of urban transformation and development. Taking Dongguan Tea Warehouse as the research object, this study interpreted the process and mechanism of urban place making from the perspective of cultural, economic, and geographical factors. The research found that: 1) Dongguan Tea Warehouse place making has gone through four stages of development: The popular tea drinking culture, the chaotic tea culture in the absence of government intervention, the economic value of tea given by capital, and the economic attributes of tea culture constructed by multiple subjects. In this process, Dongguan Tea Warehouse's material environment, functional activities, and symbolic significance have changed accordingly. 2) Territory in the spatial dimension, value in the temporal dimension, and meaning in the subject dimension of the Dongguan Tea Warehouse jointly constructed the mechanism of place making. The three dimensions are intertwined with each other and influence each other, and the cultural and economic attributes of the tea warehouses are more prominent when based on these three dimensions. 3) Dongguan Tea Warehouse place making is essentially a process of moving from culture to culture and economy, the cultural and economic attributes of tea and the significance and value of place making are mutually constructed, and the process of developing culture and economy is the process of place making in the city. Overall, this study focused on specific cases in a more macro political, economic, and cultural context, using a micro perspective to examine the transformation and development of cities through an organic combination of macro and micro perspectives. In theory, it innovatively analyzed the explanatory power of cultural and economic geography in urban place making, and in practice, it provided a practical reference path for the place making of other industrial and resource-based cities during the transformation period.
