摘　　要：应用SWAT模型对朱顺屯—大顶子山断面(66 km)的松花江流域进行小区域径流模拟,选取2010—2013年的月实测数据进行参数的率定和验证,并对模型几个重要参数敏感性分析,总结参数取值变化对模拟结果的影响规律。结果表明:模拟结果的相对误差(Re)、相关系数(R2)和月径流模拟效率系数(Ens)分别为0.09、0.84、0.78,均在保证值范围内,说明SWAT模型适用于小范围流域内分布式水文模型的建立,对松花江哈尔滨段水文模型的建立具有指导作用。A small area of Zhushuntun-Dadingzi mountain section( 66 km) of Songhua River was simulated based on SWAT,then the parameters were determined and validated by the measured data of 2010—2013. Sensitive analysis was conducted on the important parameters to summarize the influence law of parameter value changes on simulation results. The results showed that relative error of simulation results( Re),correlation coefficient( R2) and monthly runoff simulation efficiency coefficient( Ens) were 0. 09,0. 84,0. 78,Which were within the guaranteed values,indicating SWAT model is suitable for small-scaled basin to establish a distributed hydrological model and provides guidance on the establishment of Songhua River in Harbin hydrological model.
