土壤、水文综合工具(SWAT)模型的研究进展及展望

Research Progress and Application Prospect of the SWAT Model

通过文献资料法、理论讲述与现状结合分析法,综述土壤、水文综合工具(SWAT)模型在国内外的研究进展并进行应用展望。文献资料法、理论评述与现状结合分析法。研究、梳理SWAT模型在国内外的流域水文水资源管理中应用成功的案例,归纳并评述了SWAT模型在径流模拟、土壤侵蚀、非电源污染、蒸腾蒸发以及土地利用/覆被变化、气候变化对径流的影响六个方面的研究进展,指出了当前研究中存在数据资料不完备、模拟精度较低、模型自身具有局限性等问题。为进一步满足社会需求,对SWAT模型模拟土壤质地对径流的影响以及SWAT模型与WRAP模型、WEAP模型等耦合使用进行了展望。

To review the research progress and application prospect of the SWAT model around the world, re- search methods were used called literature review, theoretical analysis and analysis combined with the current situa- tion. Research results are combed successful cases of the SWAT model used in watershed hydrology and water re- sources management in the domestic, summarized and reviewed the research progress of the SWAT model in runoff simulation, soil erosion, non-point source pollution, evaporation and transpiration, the impact on runoff of land use/cover change and climate change and so on; pointed out that the data is incomplete, the simulation precision is low and the model has limitations, etc. Application prospects in order to further meet the demand of society, to simulate the effect of soil texture on runoff by the SWAT model and coupling the SWAT model with WRAP model and WEAP model are discussed.
