title: [A review on non-point source pollution models].
abstract: With the effective control of point source pollution, the non-point source pollution (NPSP) of water environment has been paid more and more attention, and NPSP models are thriving with the development of 3S technology. This paper made a brief introduction about the classification and evolution of NPSP models. Ten NPSP models commonly used abroad were selected and compared, with their software developers and providers, data input and output, pollutant- and sediment types, time scale, simulation progress and characteristics, and model types illustrated. Based on the model applications and related literature reports, a qualitative evaluation was made from the viewpoint of the suitability of NPSP models to different watershed situation. Finally, the existing research insufficiency was analyzed, and the future development trend of non-point research was discussed, which would be helpful to the development of NPSP models and their applications in water management in China.
