Advances in non-point source pollution prediction model

Transfer and transform of pollutants is very complicated.In order to prevent and control runoff pollution,the complicated processes need to be analyzed,simulated and predicted.The development of recent overseas and inland non-point pollution models is introduced in this paper.It can be seen that integrating GIS,fuzzy set theory,uncertainty analysis and risk management into non-point source pollution model will be future development direction.However,it is stil behindhand with this field in China,and remains to be developed.
