农业面源污染及其控制技术研究

Research on Agricultural Diffuse Pollution and Controlling Technology

水环境面源污染的严重性已受到国内外普遍关注,面源污染业已成为国际上水环境问题研究的活跃领域。从农业面源污染的发生机理和农业面源污染的特点出发,通过分析农业面源污染与水体环境之间的关系,探讨了农业面源污染对水环境的影响。对于面源污染的控制,最佳管理措施(BM PS)现已得到广泛应用。其中,人工湿地、前置库、缓冲带、水陆交错带、水土保持和农业生态工程等是目前研究和应用较多的农业面源污染控制技术。

The ponderance of diffuse pollution in water environment has been attentioned to generally, and the diffuse pollution was already the active field for the research on the problem of water environment in the world. This paper started from the characteristics and the occuring mechanisms of agricultural diffuse pollution, and analyzed the interrelation between agricultural diffuse pollution and the water environment, discussed the influence of agricultural diffuse pollution on the water environment. The best management praetiees（BMPs） is applied broadly in the controlling of diffuse pollution. And the constructed wetlands, primary reservoirs, buffer and interlaced strip between water and land, soil and water conservation and agricultural eco-engineering are the main technologies for the controlling of agricultural diffuse pollution in research and applying relatively.
