It found the regular understanding of ecological changes in Qinba Mountains. It is a comprehensive review and exploration on agricultural development and environmental evolution,and aims to provide a historical reference for the development of the contemporary Qinba Mountains.展开更多

Research shows that the pattern of artif icial oasis and its environment had gone through three phases: the relatively harmonious stage, the unharmonious stage, and the new fragile balance stage. It also shows that the garden and the shelter-forest are useful to the sustainable develop-ment of Qitai oasis according to grey analysis.展开更多

Based on extensive literature review, this paper systematically generalizes the connotations, research development and contents of man-land relationship in China. (1) It explores the connotations and evolvement rules of man-land rela- tionship in different social development stages in China, and finds that the core role of man-land relationship in geographical research has been strengthened continuously. Changing with times, its connotations have been considerably enriched by sustainable de- velopment and other notions, and so does its theoretical system. (2) It applies the bibliometric method to sketch out the basic research status of man-land relationship in China. Specifically, it quantitatively identifies the funding sources, major research teams and journals for publica- tion. It finds that the funding sources show a diversification trend with national funding being the primary source of research grants. The most competitive research teams are mainly concentrated in the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences (CAS) and normal universities. Journals sponsored by The Geographical Society of China are most influential in publishing man-land relationship re- search. (3) As resources and environment are the fundamental carriers of man-land rela- tionship, this study focuses further on the research on resource-environmental base of man-land relationship, and finds that the resource-environmental base research in China has gone through an evolution process from single factor perspective research to comprehensive multiple perspective research gradually. Research themes have also experienced similar changes from land, water, energy minerals or other single factor research to comprehensive factor research of resources and environment. Empirical study on national and regional de- velopment strategies is the feature of man-land relationship in China. More emphasis should be put on considering and following the changes in features of "man" and "land" and research on the impacts of new factors on man-land relationship in a developing and dynamic manner in the future. Particularly, we should pay more attention to research on the impacts of spa- tio-temporal changes in resource-environment absolute location on modes of man-land in- teraction, and to strengthening interdisciplinary research and systematic research on comprehensive techniques so as to advance the development of application of man-land rela-tionship theories and practices.展开更多
