Research Advances on Agricultural Non-point Source Pollution and Its Control

With the gradual effective renovation of point source pollution and excessive use of pesticides and fertilizers,the agricultural non-point source pollution has become a major source pollution of rivers,lakes,reservoirs and other waters.According to the analysis of causes from agricultural non-point source pollution,the main models of agricultural non-point source pollution were listed,and the application technology of combination of GIS and models was summed up.Meanwhile,the effective prevention and control measures of agricultural non-point source pollution were proposed practically from different angles.Finally,based on the current research progress,the points that the development of ″3S″ technology,the biotechnology dominated by genetic engineering and the combination of science technology and BMPs would be the focus of agricultural non-point source pollution research in the future were put forward.
