Status and Control Measures of Agricultural Non-point Pollution

The agricultural non-point source pollution is the key section of non-point source pollution as well as the most universal non-point source pollution.Its main characteristics are the randomness of the region where the pollution takes places,the uncertainty of the effluent pathway and the discharged effluent,the diversity of the spatial distribution of the pollution load.With the effective governance of the point source pollution in domestic life and industry,the agricultural non-point source pollution has been a hot topic.Based on the concept of Non-point pollution of agriculture,this paper firstly discusses the pathway of pollution,the main pollutants,the status quo and hazards,then briefly introduces the control measures of non-point pollution,finally makes prediction for the trend of its research orientation.
