In these years, with the increasingly serious human damage to the water environment, the world is seeing a more gloom prospect for water pollution control, and non-point-source pollution accounts for the major cause of water pollution. Currently, establishing non-point-source pollution load models to simulate the formation, transfer and load capacity of the non-point sources has become a major solution to control and treatment of non-point source pollution. The present study selected two classic basin-scale non-point source pollution distribution models — SWAT and HSPF, introduced their respective structures and application, and compared comparative analysis. The existing challenges and development trend of non-point source pollution models in China were also explored.
