摘要
狮泉河宽谷区的荒漠化过程以整个青藏高原的环境演变为背景，受人为的资源利用不合理而强化。今天的宽谷景观一方面隐含了高原宽谷的变化，一方面显示出干旱，退化的主导特征，较之西北干旱区，生态系统更具脆弱性。荒漠化的治理应在发挥区内水资源优势的同时强调生态系统自身的稳定。
The desertification of the Shiquanhe wide valley occurs on the background of environmental degradation of the Qinghai─Xizang plateau and is strengthened with manmade irrational use of natural resources. The present landscapes of the wide valley,on the one hand,reveal the process of themselves succession,on the other hand,manifest the main characteristic of dryness and degradation. The arid eec-system of the wide valley is more vulnerable than that of the arid zone of the northwestern China. The control of desertification should lay stress on the stability of eco-system,meanwhile,bring into full play to superiority of water resources.
