| 摘 要： | 1 INTRODUCTION Environmental changes caused by mankind's exploitation and regional climate changes have long been a severe problem in the world, especially in the arid and semiarid areas because of their ecosystems' vulnerability (Chen & Qu, 1992; Wang & Cheng, 1999; Liu et al., 1999). During the last half-century, especially the last 30 years, drastic environmental changes have occurred owing to exploitation and development, which have invoked society's concerns. In the Qinghai-Tibet …

| Abstract: | The issue on water environmental degradation in the source area of the Yellow River has been one of very serious ecological and socially economic problems. The temporal-spatial changes of water environment led to the decreasing of land capacity and river disconnecting. The status of water environmental degradation in this paper was analyzed based on the data and field investigation. The results indicated that the surface water area in the region has obviously decreased owing to the climate changes and human irrational use of water resources and the continuous lowering of the regional groundwater table and the steadily decreasing tendency of the flow rate in the source areas of the Yellow River. |
