Research progresses in agricultural non-point source pollution caused by soil erosion

The agricultural non-point source pollution(AGNSP)caused by soil erosion is a key pollution source of the water quality deterioration.The paper reviews in detail the research progresses in the AGNSP caused by soil erosion for the past 20 years,including the pollutant transport processes,the affecting factors,the prediction models,and the control measures,etc. This paper also proposes the key research fields of the AGNSP in China,including the effect of erosion process on the agricultural pollutant movement and the water quality,the prediction model of AGNSP.We have worked out the standard indicator systems of the different pollutant risk-assessment.
