ArcSWAT模型在流域水环境管理中的应用进展

目前在不同领域SWAT模型的运用日益增多,其扩展模块ArcSWAT模型因软件强大、界面友好也逐渐运用到国内外气候、泥沙、非点源污染等领域的模拟中。通过文献的梳理和分析,ArcSWAT模型的运用范围主要是流域水文循环、土壤侵蚀、污染物负荷、气候变化与土地利用变化的影响几个方面。分析了ArcSWAT模型存在的局限性,对其未来发展进行了展望,以期为ArcSWAT模型更好地应用于实际提供参考。

At present,SWAT model is increasingly used in different fields.Its extension module ArcSWAT model is gradually used in the simulation of climate,sediment,non-point source pollution and other fields at home and abroad due to its powerful software and friendly interface.Through literature review and analysis,the application scope of ArcSWAT model mainly covers hydrological cycle,soil erosion,pollutant load,climate change and land use change.Some limitations of ArcSWAT model are pointed out,and the future development of ArcSWAT model is expected to provide reference for better application of ArcSWAT model in practical problems.
