Agricultural Non-point Source Pollution and Cure Measures

农业非点源污染是最主要的一类非点源污染,也是最普遍的非点源污染,其主要特征为发生区域的随机性、排放途径及排放污染物的不确定性、污染负荷空间分布的差异性。随着对城市生活点源和工业点源污染的有效治理,农业非点源污染引起了人们的广泛关注。为此,分析了农业非点源的污染现状、机理及来源,并根据农业非点源污染存在的问题,提出了农业非点源污染的防治措施,旨在为非点源污染的防治提供参考。

The agricultural non-point source pollution is the most main kind of non-point source pollution, it is also the most universal non-point source pollution, its main characteristic is the randomness of the region where the pollution takes places, the uncertainty of effluent approaches and pollutant effluent, the diversity of the pollution load spatial distribution, With the effective governance of the point source pollution in domestic and industry, the non-point source pollution in agriculture has been a topic of wide concern. The pollution actuality state, the mechanisms and the source was analyzed in this paper. Put forward prevention and cure measures according the problems in the present agricultural non-point source pollution.
