【 摘 要 】

Coal mining is a major cause of decreases in river runoff, which can increase the disparity between the supply and demand of water resources. This paper presents runoff variation data from Tou-Tong to analyze the impacts of rainfall and human activity on runoff. This data showed that the annual runoff of Gushanchuan, Kuye and Tuwei river decreased significantly in the middle and latter half of the 1990s. Reservoirs, key dams, terraced fields and vegetation variation are all important factors that affect decreases in runoff. The effect of three types of coal mining on the water cycle is put forward and quantitatively calculated.
