| 中文摘要: |
| 农药非点源污染指农药自田块流失产生经水沙传输到水体，并通过迁移转化最终进入并残留在各个环境介质中，从而对生态环境产生不利影响的污染，非点源模拟模型能为农药污染防控和管理提供更科学的理论和技术支撑。本文通过对国内外研究进行梳理，从农药环境流失、传输、归趋的角度，综述了各类模型的方法、特点和应用。对代表性模型进行综合分析，总结出现有模型存在的问题，即对农药环境行为考虑不完善、结果存在不确定性以及对决策和管理支持不足等，并从多方面对模型进行了展望，未来农药非点源模拟将向机理化、精准化、动态化和决策支撑等方向发展。 |
| 英文摘要: |
| 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. |
