| Abstract: |
| In order to clarify the evolution history of the non-point source pollution estimation model and explore the development trend of the model, based on a systematic investigation of a large number of non-point source pollution research literatures, a detailed review of the process of the domestic and foreign non-point source pollution model research to date is summarized to summarize the results of the non-point source pollution model research. Model types, a simple analysis of research results on the use of various models at home and abroad, and the characteristics and applicable scope of various models are also reviewed. According to the comparison of the models and the application requirements, it is considered that SWAT and output coefficient models are widely used in the non-point source pollution model. Selecting and improving the non-point source pollution model according to the actual conditions of the study area is the trend of studying non-point source pollution. |
