青海湖地区环境变化对动物区系演变影响的探讨

摘要:
青海湖地区近百年来由于气候干暖化趋势增强,湖周植被、土地退化,人类经济活动加剧,湖区青藏高原动物成分的种类和数量减少,但蒙新及华北动物区系成分则有增加趋势,致使该区动物区系成分发生显著变化。从青海湖地区动物区系形成来看,决定动物区系演变的原因主要是气候、生物等生态因子的综合作用,人为因子影响仅在近30年来才日益突出。

Abstract:
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.
Key words:  Environmental change  fauna evolution  Qinghai Lake Region
