全球变化背景下中国自然地域系统研究前沿

中国地域辽阔,基于陆地表层地域分异规律,开展自然地域系统研究是支撑自然资源有序开发和产业合理布局、保障区域可持续发展的重要基础。本文在总结分析中国自然地域系统及相关方法研究进展的基础上,探讨全球变化背景下自然地域系统研究前沿问题。1950s以来,伴随着社会经济发展,中国高度重视自然地域系统研究,包括综合自然区划、生态地理区划和综合区划工作,目前随着全球变化研究的深入,地域系统的动态研究被高度关注。在此过程中,研究方法从以专家智能集成为主的定性研究,逐步发展至以观测、实验和信息技术、数理模拟方法为主的定量研究。随着全球变化研究的日益深入,自然地域系统研究将与未来地球计划的理念、目标和研究内容结合,重点开展陆地表层关键要素相互作用机理及区域效应,地域系统对全球变化的动态响应,陆地表层地域单元界线定量化识别等研究,加强地域系统研究中自然要素与人文要素的结合。

Frontiers in terrestrial system research in Chinaunder global change

In view of the regional differentiation rules of land surface, research on terrestrial system (TS) has provided significant basis for the rational development of natural resources and layout of industries, and supported regional sustainable development as well. In this paper, the progress of TS research in China is overviewed and research frontiers in TS research in the near future under global change are explored. Since the 1950s, 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. Along with the emphasis on global change, TS would be combined 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 combination of physical and human elements.
