文摘内容 Human beings have had a tremendous impact on natural ecosystems and are now the principal power to change the biosphere.It is logical that we should pay close attention to the interaction between human systems and environ-mental systems.Taking Minqin bsin ,Gansu Province,as a case,this paper focuses on the evolution of regional physic-cal environments and the cultural systems by which people maintain their relationships with those environments.This pa-per presents the conceptural framework for the man-land system.Expecting to accelerate the regional sustainable develop-ment,it also analyses the evolutionary mechanism of regional man-land system.On the basis of reviewing and analyzing the evolution of man-land system in Minqin basin,the paper also brings forward an adujusting mode for the studied area, which consists of three aspects:to build up a concept that economic growth must harmonize with environmental qualityˊs and land productivityˊs improvement;to make a whole planning and management in the drainage area;and to push for-ward the technique of water-saving irrigation and establish water-saving agricultural system. Itˊs meaningful for resource exploitation and sustainable development of Chinese northwestern arid area,which is represented by Minqin basin,by under-standing what great changes the basin has experienced is experiencing at the global background,and studying its time standing what great changes the basin has experienced and is experiencing at the global background,and studying its time order and territorial structure ,the systemˊs character and law of evolution,trend and the regulating ways to improve man-land relationship。
