摘要
分析了国内外水、土、气、生主要陆表过程的相互作用以及干旱、半干旱区主要陆表过程与气候变化和人类活动互为响应机制的一系列研究成果,提出了未来该研究领域的发展方向应集中在地球表层系统各要素相互作用的综合研究,同时突出人类活动在陆表过程中的主导地位;在研究手段上应基于国家野外科学观测站、生态网络站的长期定位观测,开展干旱、半干旱区不同尺度水、土、气、生过程相互作用机理及其联网对比、集成研究。最终通过深刻理解研究区陆表过程及其调控机理,丰富陆地表层系统科学研究的内涵,带动相关学科在交叉集成研究上的理论创新。
After analyzing the international and domestic study results of relation among all kinds of factors (water-soil-atmosphere-ecology) of land surface system and interaction between the development of land surface system and climate change and human activity, this paper put forward future study aims and methods in related study field. The comprehensive study and understanding on the interaction among all factors inside land surface system should be the main future study object. Besides, the impact and affection of human action on land surface system should also be the other predominant object. And these long time data of all kinds of factors in different levels resulting from the national field observational stations and ecological located net stations should be used to comprehensively and integrated understand the interaction and mechanism, which can enrich the study content of system science in future and drive the theory innovation in related subjects.
