摘要
Abstract
By single-factor-index evaluation on water of earth's surface, the result shows that the water-quality keep Ⅲ grade on the whole in Yang-tze River, Jia-ling River and Wu River of the Three Gorges reservoir, it occurs no obviously deteriorated tendency in 2005. But some sub-grade rivers are polluted badly, cross-section amount of water-quality Ⅰ , Ⅱ , Ⅲ only has 64 percent, their water-quality is bad. It is clear that the gap between the water environmental state and the object of keeping water- quality Ⅱ in the Three Gorges reservoir is very big. This paper thoroughly analyses the problems and causes of the water environment, points out that the main factors resulting in the water pollution in recent years include the industrial sewage, solid wastes, soil and water loss, domestic rubbish and agricultural non-point source pollution, and finally puts forward the countermeasures for protecting of the water environment in the Three Gorges Reservoir.关键词
