三峡库区农业面源污染现状及控制对策研究

The agricultural non-point pollution in the TGP reservoir area and control countermeasures

农业面源已成为引起库区生态环境问题、暴发水环境污染事件的主要贡献源。就农业面源的产生、分布、特征、形成进行了分析。三峡库区农业面源污染的现状及对库区水质的影响进行了分析。三峡水库蓄水后,许多库湾、库汊处已出现富营养化现象。论证了农业面源对河流水质影响的形成机理,指出面源污染是未来水体污染发展趋势,潜在的污染问题。针对三峡库区农业面源污染现状提出了治理控制对策与建议。

The agricultural non- point pollution has become a main factor causing ecological environment problem and pollution event. This paper analyses the emergence, distribution, features, formation of agricultural non - point pollution and gives a practical example of ecological environment damage by agricultural non - point pollution in TGP reservoir area, demonstrates the formation mechanism of water quality impact by agricultural non - point pollution, points out the pollution development tendency and the potential pollution problem, puts off the pollution control measures and suggestions of agricultural non - point pollution in the reservoir area.
