摘　　要：SWAT模型是美国农业研究中心研发的专门针对流域水文过程和非点源污染模拟的分布式水文模型,在我国有较为广泛的应用。由于美国同我国的土壤指标的分类标准不同,导致SWAT模型中土壤数据库的本土化构建较为困难,目前已成为制约其在我国进一步推广的瓶颈。鉴于此,为寻求更为便捷、高效的参数确定途径,对SWAT模型土壤物理属性数据库的本土化构建进行了相关研究,并将构建好的SWAT模型用于洪安涧河上游东庄水文站以上流域的水文过程模拟。结果表明,相关系数R^2达到了0.875,效率系数E_(ns)达到了0.840,取得了较好的模拟效果。该研究为建立符合我国国情的土壤物理属性数据库提供了思路和方法,可进一步促进SWAT模型在我国的应用,可为流域水文模拟提供技术支撑。SWAT,widely used in China,is a distributed hydrologic model developed by the United States Department of Agriculture,specialized for simulation of basin hydrological processes and non-point source pollution.Because of differences in standard of classification of soil index between China and the United States,it brings great difficulties in localization of soil physical property database of SWAT model and becomes a bottleneck to the further promotion of SWAT model in China.In order to find a more convenient and efficient way to determine the parameters,this paper studied the localization of soil physical property database of SWAT model,and applied the constructed SWAT model to the simulation of hydrological processes in basin up the Dongzhuang Hydrological Station in the upstream of Hong′an River.A good simulation result that the correlation coefficient(R 2)is 0.875 and Nash-Sutcliffe coefficient(E ns)is 0.840 is obtained.This research provides ideas and methods for establishing the soil physical property database in line with our national conditions,promotes application of SWAT model in China,and offers a technological support for basin hydrological simulation.
