Abstract: 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.
