The expansion and upgrading of Chinese industries have accompanied with the spatial restructuring process across the country. This paper provides a literature review on China's industrial geography, paying special attention to industrial agglomeration and industrial clusters. The increasing industrial agglomeration and development of industrial clusters have been the prominent characteristics of dynamics of industrial landscape in China. The major driving forces of China's industrial geography include economic globalization, decentralization and regional competition and rebuilding of regional advantages. This paper concludes with a discussion of future research focus.  相似文献

Geomorphometry,the science of digital terrain analysis(DTA),is an important focus of research in both geomorphology and geographical information science(GIS).Given that 70% of China is mountainous,geomorphological research is popular among Chinese scholars,and the development of GIS over the last 30 years has led to significant advances in geomorphometric research.In this paper,we review Chinese progress in geomorphometry based on the published literature.There are three major areas of progress:digital terrain modelling methods,DTA methods,and applications of digital terrain models(DTMs).First,traditional vector-and raster-based terrain modelling methods,including the assessment of uncertainty,have received widespread attention.New terrain modelling methods such as unified raster and vector,high-fidelity,and real-time dynamic geographical scene modelling have also attracted research attention and are now a major focus of digital terrain modelling research.Second,in addition to the popular DTA methods based on topographical derivatives,geomorphological features,and hydrological factors extracted from DTMs,DTA methods have been extended to include analyses of the structure of underlying strata,ocean surface features and even socioeconomic spatial structures.Third,DTMs have been applied to fields including global climate change,analysis of various typical regions,lunar surface and other related fields.Clearly,Chinese scholars have made significant progress in geomorphometry.Chinese scholars have had the greatest international impact in areas including high-fidelity digital terrain modelling and DTM-based regional geomorphological analysis,particularly in the Loess Plateau and the Tibetan Plateau regions.  相似文献

As an important branch of human geography, transportation geography has experienced three periods of evolution: foundation, systematization, and rapid development of the discipline. It has gradually become a relatively mature discipline. During the period 1930– 1980, the development of transportation geography consisted mainly of the publication of theoretical texts. During 1980–2000, it gradually became a systematic discipline. Since the start of the 21 st century, transportation geography has focused mainly on exploring the impacts of transportation on socio-economic development. Currently, studies on transportation geography have led to significant developments in a number of areas, including transportation theory, facility distribution and planning, transportation flows and network analysis, evaluation of transport modes, transportation planning, and simulation and assessment of urban transportation. Such studies have also enriched human geography research, provided a wider geographical overview and elucidated the development mechanism of transportation, as well as helped to understand the impacts of transport development on socio-economic systems. Some findings obtained by geographers have been widely used in transportation geography and related fields, including the four basic laws of transportation generation, the hub–spoke mode of transport organization, the subordinating and guiding functions of transportation on socio-economic development, regional transport dominance measures, accessibility measures, and spatial organization of port systems.  相似文献

Economic geography in China's mainland has developed in a different way from that in many other countries. On the one hand, it has been increasingly active in participating in academic dialogues and knowledge development led by Anglophone countries; on the other hand, it takes practice-based and policy-oriented research, i.e. satisfying the demands from the Chinese government and society, as the linchpin of research. Since there has been a lot of literature reviewing the development of economic geography in the country before the new millennium, this paper will make a comprehensive analysis of the discipline in 2000–2015, based on a bibliometric survey and research projects done by Chinese economic geographers. The analysis indicates that(1) economic geography research in China's mainland is unevenly distributed but concentrated in several leading institutions;(2) traditional research fields like human-nature system, regional disparity, industrial location and transportation geography remain dominant while new topics such as globalization, multinational corporations and foreign direct investments, information and communication technology, producer services, climate change and carbon emission emerge as important research areas;(3) Chinese economic geography is featured by policy-oriented research funded by government agencies, having considerable impacts on regional policy making in China, both national and regional. To conclude, the paper argues that the development of economic geography in China's mainland needs to follow a dual track in the future, i.e. producing knowledge for the international academic community and undertaking policy-oriented research to enhance its role as a major consulting body for national, regional and local development.  相似文献

The world is currently undergoing profound changes, with a shift in global power centers and reordering of international power spaces, assigning new theoretical tasks as well as providing new opportunities for geopolitics research in China. Despite the peripheral nature of geopolitics research within their discipline, geographers have played a fundamental role in its origins and revival, from classical geopolitics(i.e., the German school of geopolitics and the Anglo-American school of geo-strategy), to internal geopolitics(i.e., electoral geography and administrative geography), to the new geopolitics(i.e., formal geopolitics), and to recent critical geopolitics(i.e., popular geopolitics). Although only few of these researchers were from China, great strides have been made in geopolitics and political geography research in China, with useful results being obtained. After demonstrating the importance of geopolitics research for the rising China, this review provides an overview of geopolitics papers led by China's geographers in the past few decades, describing their achievements, the problems they have faced, and the directions they have taken. Twenty-five years of geopolitics have produced a range of accomplishments, with a growth in the quality and size of research groups and institutions, an expanding literature, and some geo-strategic breakthroughs. Obviously, geographers have successfully reclaimed geopolitics, but some crucial topics are still absent or weak in the geopolitical research agenda, and need to be pursued vigorously. Most of the attention, from a positivistic perspective, has been paid to reflecting Western geopolitical thoughts, describing patterns of international power relations, and offering foreign policy advice(in a problem-focused orientation), rather than determining mechanisms and performing theoretical analyses(in a theoretical orientation), resulting in a lack of independent value judgments and of a theoretical basis for the subject. Moreover, in comparison with other disciplines, in terms of its academic community, research output, and status as a discipline, geopolitics research is very different from how it was three or four decades ago, when it was mainly the property of geographers, rather than political scientists and diplomats. For now, whether to support national geo-strategies or to enhance the diversity of the discipline, the involvement of geographers in geopolitics needs to become both more intensive and more extensive. The top priority is to strengthen theoretical, methodological, and problem- oriented research, including studies of geopolitical philosophy and methodology, the theoretical framework of the subject, global geopolitical evolution and shifts in power space, the roles of major powers and their geo-strategies, as well as China's surrounding geopolitical environment.  相似文献

Based on a large number of domestic literature reviews with related research abroad, academic standards and issues awareness have been intensified in domestic tourism geography, disciplinary consciousness and innovation enhancement. Hence, some valuable achievements have been made in the areas of tourism resources, tourism regional system, the spatial structure of tourism, tourism flow, ecotourism, tourism industry, tourism planning and tourism impacts, which strengthened the traditional advantages of research, expanded new areas of research and made research trends diverse. Meanwhile, with innovation of research methods, tourism geography in China is getting more and more internationally-oriented and reflecting Chinese characteristics. Research trends of China's tourism geography are prospected: 1) Catering to national strategic needs, persisting problem-oriented, strengthening the metatheoretical research, and building Chinese "localization" of theory of tourism geography and method system. 2) Introducing and assimilating foreign theories and research methods, while focusing on explaining new tourism phenomena and problems in the domestic socio-economic background. 3) Concerning about the new regional spatial processes of demographic process, social process, and spatial process in new tourism trend. 4) Exploring interactive process and mechanism of man-land relationship and new models to develop territorial space under the tourism impacts. 5) Exploring important research issues of tourism geography in global, national, regional and local scales, from the point of view of spatial differentiation, scale transformation, interaction of man and nature, creating tourism geography interpretation system based on "process-structure-mechanism" of China. 6) Building theoretical system actively, while strengthening application-oriented research, and focusing on tourism poverty alleviation, tourism and heritage protection, national parks' construction and other hot issues. Faced with econometrics research boom, we should return to rational thinking, using big data scientifically, while paying attention to the important role of qualitative evaluation in future research.  相似文献

This research examines the distribution features of 4960 caves across Guizhou Province, while probing the relationship between the caves' spatial patterns and geographic elements. This study is based on hydrogeological and topographic maps of Guizhou. Arc GIS software was used to process the adjacent index, spatial analysis, and coupling analysis of the caves altitude and longitude, as well as the rock properties, lithology, drainage and tectonic division of almost 5000 caves. Based on a point pattern analysis of Guizhou caves, the adjacent index is 0.53, and the coefficient of variation verified by Tyson polygon reached 72.469%. This figure reflects the clustered distribution pattern of the caves. Across the entire province, caves are divided into four concentrated areas and one weakly affected area. The four concentrated areas are Zunyi-Tongren, Bijie, Qianxinan-Liupanshui, and Guiyang-Anshun-Qinan. The one weakly affected zone is Qiandongnan. The most concentrated among them is the Guiyang-Anshun-Qiannan area, which covers 24.67% of the total province area, and accounts for 36.63% of the total province's caves. Cave distribution in Guizhou is characterized as dense in the western part and sparse in the eastern part. Under this study background, the natural elements of formation, including lithology, structure, climate, hydrology, and altitude, and their effects on the distribution, number, and spatial pattern of cave development is analyzed.  相似文献

Land surface is of spatial-temporal heterogeneity. Terrestrial system(TS) comprehensively studies on land surface and physical regionalization objectively describes geographical zonation of the system. China has a vast area with apparent spatial variations in resources and environmental conditions, which highly influence on socio-economic development. In this paper, progress of the TS studies in China is overviewed and research priorities in the near future are prospected. Since the 1950 s, China has paid great attention to the TS study as its socio-economic development, and conducted research on physical geographical regionalization, eco-geographical regionalization and comprehensive regionalization. Along with the deepening of global change research, dynamics of TS have been highly concerned. During the studies, methodology has been developed from qualitative research of integration of experts' brainpower gradually to quantitative research based on field observation and experiments of the natural processes, including physical, chemical and biological processes, as well as application of information technology and mathematical simulation. In the near future, TS would combine with the ideology, objectives and key researches of Future Earth program, to focus on the mechanism and regional effects of interaction among land surface elements, the response of TS to global change, the quantitative recognition on regional unit boundary, and the application to TS in sustainable socio-economic development.  相似文献

Since the 1950 s, noteworthy farmland abandonment has been occurring in many developed countries and some developing countries. This global land use phenomenon has fundamentally altered extensive rural landscapes. A review of global farmland abandonment under the headings of "land use change – driving mechanisms – impacts and consequences – policy responses" found the following:(1) Farmland abandonment has occurred primarily in developed countries in Europe and North America, but the extent of abandonment has varied significantly.(2) Changing socio-economic factors were the primary driving forces for the farmland abandonment. And land marginalization was the fundamental cause, which was due to the drastic increase of farming opportunity cost, while the direct factor for abandonment was the shrink of agricultural labor forces.(3) Whether to abandon, to what extent and its spatial distributions were finally dependent on integrated effect from the physical conditions, laborer attributes, farming and regional socio-economic conditions at the village, household and parcel scales. With the exception of Eastern Europe, farmland abandonment was more likely to occur in mountainous and hilly areas, due to their unfavorable farming conditions.(4) A study of farmland abandonment should focus on its ecological and environmental effects, while which is more positive or more negative are still in dispute.(5) Increasing agricultural subsidies will be conductive to slowing the rate of farmland abandonment, but this is not the only measure that needs to be implemented. Due to China's rapid urbanization, there is a high probability that the rate of abandonment will increase in the near future. However, very little research has focused on this rapid land-use trend in China, and, as a result, there is an inadequate understanding of the dynamic mechanisms and consequences of this phenomenon. This paper concludes by suggesting some future directions for further research in China. These directions include monitoring regional and national abandonment dynamics, analyzing trends, assessing the risks and socio-economic effects of farmland abandonment, and informing policy making.  相似文献

The spatiotemporal landscape heterogeneity implies multiple biodiversity mechanisms across scales, and the cross-disciplinary studies between landscape ecology and biodiversity are becoming a new research field in China. This paper briefly reviews the development of the field by comparing papers published in international journals and Chinese journals;then it investigates the differences in the trends and focuses between international and Chinese studies. We also introduce several study areas that have emerged over the last 10 years in this field, including metacommunity assembly, landscape genetics, biodiversity and ecosystem service relationship, and landscape planning for biodiversity conservation. The major advances emerging in this field in China over the past 5 years can be classified into six subject areas: 1) effects of urban landscape and urbanization on biodiversity;2) altitudinal patterns of biodiversity in mountain landscapes;3) effects of topographic heterogeneity on plant community assembly and species coexistence;4) impacts of landscape patterns and processes on animal behaviors;5) forest fires and spatiotemporal patterns of vegetation responses;and 6) landscape ecology applications in natural conservation planning and design. In an attempt to promote cross-field studies between geography and ecology, this special issue collected 10 research articles, involving multiple landscape types and biological assemblages, in order to explore the interaction between landscape features and biodiversity. We anticipate that the future development of this active front will be primarily driven by the application of novel information techniques and the realistic demands of sustainability issues, in addition to answering scientific questions cross scales.  相似文献

In this paper, we compared the concept of agricultural drought and its relationship with other types of droughts and reviewed the progress of research on agricultural drought monitoring indices on the basis of station data and remote sensing. Applicability and limitations of different drought monitoring indices were also compared. Meanwhile, development history and the latest progress in agricultural drought monitoring were evaluated through statistics and document comparison, suggesting a transformation in agricultural drought monitoring from traditional single meteorological monitoring indices to meteorology and remote sensing-integrated monitoring indices. Finally, an analysis of current challenges in agricultural drought monitoring revealed future research prospects for agricultural drought monitoring, such as investigating the mechanism underlying agricultural drought, identifying factors that influence agricultural drought, developing multi-spatiotemporal scales models for agricultural drought monitoring, coupling qualitative and quantitative agricultural drought evaluation models, and improving the application levels of remote sensing data in agricultural drought monitoring.  相似文献

Urban-rural transformation and rural development are issues at the forefront of research on the topic of the urban-rural relationship in the field of geography, as well as important practical problems facing China's new urbanization and overall planning of urban and rural development. The Center for Regional Agricultural and Rural Development, part of the Institute of Geographic Sciences and Natural Resources Research under the Chinese Academy of Sciences, was established in 2005. The Center has laid solid foundations for integrating research in the areas of agricultural geography and rural development in China over the past decade. The paper aims to review the major achievements in rural geographical research in China during the past decade, analyze innovative developments in relevant theories and methods, and suggest prospects and countermeasures for promoting comprehensive studies of urban-rural transformation and rural geography. The research shows that innovative achievements have been made in rural geography studies of China in the past decade as major national policy development, outputs of result and decision making support; new breakthroughs have been achieved in such major research projects as geographical integrated theory, land remediation projects and technology demonstration projects, new urbanization and urban-rural integration; significant progress has been made in actively expanding the frontiers of rural geography and pushing forward theoretical innovations in land and resource projects; and, with China's development goals of building a moderately prosperous society in all respects and achieving modernization in mind, future innovative developments in agricultural and rural geography should aim to make research more strategic, systematic, scientific and security-oriented, with attention given to promoting systematic scientific research on international cooperation and global rural geography.  相似文献

Micro-perspective studies on economic geography in China can be classified into geography of the enterprise, geography of the rural household, and small-scale studies on economic activities. Literature on geography of the enterprise includes spatial expansion of the enterprise, industrial location, firm's networks, industrial relocation, industrial clusters, and the relationship between industrial organizations and the environment. Studies on geography of the rural household(GRH) include the theoretical framework of GRH, the locations of rural economic activities, and the interrelation between rural households and geographical environment. Small-scale studies focus on human-land interaction from a land plot perspective, relations between specialized villages and the environment, and regional sustainable development research at site-specific scale. Micro-perspective studies on economic geography attempt to search for the basic unit of economic-geographical landscape, exploring the geographical process and the formation mechanism of geographical phenomena. The exploration of these three perspectives anticipates new approaches to economic-geographical studies with China's special background.  相似文献
