摘要
以经济活动为主要依据，结合人群文化和环境生态特质，概括了我国山区人地系统基本结构类型．通过对人地系统结构变化的动力及作用机制分析，预测我国山区人地系统的主要变化趋势．从持续发展角度，提出了我国山区人地系统结构优化的特殊性及要点．
According to the productive activity and concurrently the cultural traits of the crowd,as well as the geomorphic features,land resource and specific ecologic propreties of the environment in the area corresponded to the crowd, the main forms of man-land system in the mountainous region of China and their structural characteristics have been macrcacopically summarired. Thebasic frame of the typical several man-land Systems is Shown in the appendend chart. And then, by analysis of the potential source and mechanism of motive force driven the structural change of man-land system,predicte the trends of the structural change. It have been indicated that the main 3 motive forces, i. e. the disturbance force come form the pressure of population,the pull force caused by the interflow of commodities and cultural exchange,and the push force come from the institution-culture such as policy, socio-economic system etc. are affecting the man-land system in the mountainous region of China. And the structure of man-land system in different mountainous region with different ecologic and environmental charactsristics and socityeconomic conditions may be shown as 4 change trends:go backward the natural ecologic system, retrogressiveness change, maintainability change and progressiveness change.Finally, from the angle of sustainable development, the relation between the sustainabledevelopment of the mountainous region and the structural ophmization of man-land system has been discussed. It hsa been POinted out that structural optimiration of man-land system in the mountainous region of China should emphasize 3 key points: the optimization on the boundary of man-land system, productive structure and site and mode of contact between man and land.
