Agricultural Nonpoint Source Pollution Model Analysis and Application

Abstract:

With the point source pollution was effectively treated, non-point source pollution, especially the agricultural non-point source pollution (ANPSP), is becoming the main problem in environment. The research is focused on the model analysis and application, which could be scientifically distinguish and effectually control ANPSP. Four kinds of models were introduced here with the development of non-point source pollution, as experience statistical model, mechanism model, function model, improved model by 3S technology and the uncertain analyze. Among these models, HSPF and SWAT model were successfully applied in best management practices (BMP) for ANPSP control. In the future, our country should base on the introduction of the foreign mature techniques, which combine the 3S technology and the uncertain improved model, then enhance the autonomous model research and build the basic database.
