| Abstract: |
| Pesticide non-point source pollution refers to pesticides generated from the field, which are transported into waterbodies by runoff and erosion and enter and remain in various environmental media, thereby adversely affecting the ecological environment. Pesticide non-point source models can provide a more scientific basis and technical support for pesticide pollution prevention and management. In this study, the methods, characteristics, and applications of the respective models based on different simulation methods of pesticide loss, transport, and fate were assessed through a review of domestic and international studies. A comprehensive analysis of the three types of representative models concluded that the limitations of the models were as follows： imperfect consideration of pesticide environmental behavior, uncertainty of results, and insufficient support for decision making and management. We discussed the future outlook of the models from various aspects to provide a comprehensive reference for the selection of pesticide non-point source simulation tools, which will facilitate the mechanization, precision, dynamics, and decision of using pesticide non-point source simulation. |
