我国农业非点源污染研究进展分析

非点源污染具有分散性、隐蔽性、随机性、滞后性和形成机理复杂等特征,目前以模型方法为主要研究手段。介绍了比较著名的流域尺度的非点源污染模型AGNPS模型、SWAT模型和输出系数模型。指出我国的农业非点源污染研究开始于20世纪80年代初,目前以引进国外模型进行验证、应用为主。从研究区域上看,目前国内的非点源污染研究多集中在南方地区。

Non-point source pollution is often dispersed,hidden,random,lag and complex of mechanism.As the main research tool,more well-known non-point source pollution model of the river basin scale are AGNPS model,SWAT model and export coefficient model.The research in agricultural non-point source pollution began in the early 1980s,and the models above are verified and applied in China.From the point of view of the study area,the domestic non-point source pollution is more concentrated in the south China.
