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is a comprehensive review and exploration on agricultural development and environmental evolution,and aims to provide a historical reference for the development of the contemporary Qinba Mountains.展开更多

The type, area, distribution and damage of desertification land in the Yarlung Zangbo River basin are firstly analysed in detail by using latest investigation information. According to the classification criteria of desertified land types and grades, the desertified land in the Yarlung Zangbo River basin can be divided into three grades and five types: fixed sand (dune) land, semi bare sand and gravel land, semi fixed sand (dune) land, base sand and gravel land, and shifting sand (dune) land. The desertified lands in the basin are mainly distributed in the wide valley floor and tributary junction area. The main factors affecting desertification are fragile eco environment, climate warming and drying and over exploitation of land resources. The man made factors leading to desertification in the Yarlung Zangbo River basin are over cutting and over grazing, dominated by over grazing.展开更多

The following balanced land use model is proposed： the harmonious and interactive relationship between man and nature, two main bodies of land ecological system, constitutes the mechanism of land resources security; The feedback relationship between man and nature is the basis for the land resources security and the core is the relationship among people established for the benefit equilibrium in land use. The conflicts in land use stem from the rarity of land resource and the solution to those conflicts in harmony helps land resource security.展开更多
