Abstract:

To clarify the evolution history of the non-point source pollution estimation model and explore its development trend, based on a systematic investigation of a large number of non-point source pollution research literature, a detailed review of the development process of domestic and foreign non-point source pollution model research was conducted. Model types, application results of various models at home and abroad, and the characteristics and applicable scopes of the models were also summarized. According to the comparison of the models and the application requirements, it is considered that SWAT model and output coefficient model are widely used in the non-point source pollution estimation. Selecting and improving the non-point source pollution estimation model according to the actual condition of the study area is the trend of non-point source pollution research.

Key words: non-point source pollution, estimation model, model characteristics, uncertainty, SWAT model, output coefficient model
