|The species and quantity of the fauna in Qinghai-Xizang Plateau decreased in the past century because of the drying and warming tendencies of climate and hence the degradation of vegetation and soils around the lake as well as the intensification of cultivation.However,the fauna belonging to Inner Mongolia,Xinjiang and North China tend to be increased resulting to a considerable change of the fauna in the area.In the view of the formation of the fauna in Qinghai Lake region,what controlling the fauna evolution are no other than the comprehensive ecofactors such as climate and biology,but it is about thirty years ago that human activities began to have impact on the lake environment.
