摘要
SWAT(Soil and Water Assessment Tool)是一个具有很强物理机制的长时段的流域分布式水文模型。该文以华北土石山区云州水库流域为例,运用了SWAT模型自动校准模块来进行参数率定和检验,研究了SWAT模型自动校准模块的应用。通过模型自动校准、调整参数,使模型能够比较准确地模拟该流域的径流量。同时,经过模型有效性检验,计算得到,确定性系数为0.78,径流模拟值与实测值拟合度较好。从模拟结果可以看出,SWAT模型自动校准模块在云州水库流域的应用是较为成功的。
SWAT （Soil and Water Assessment Tool） is a periods which has very strong physical mechanics. This distributed hydrological model of basin for long paper has taken the Yunzhou reservoir basin in north Beijing mountain area as the example, the application of the automatic calibration module of SWAT model was studied by using the automatic calibration module of SWAT model to do parameter rating and test. By automatic adjusting and parameters adjusting, the runoff was simulated accurately. At the same time, by the model effectiveness testing, the value of Ens is 0.78, the fitting degree of the simulation val- ue and the measured value is high. From the simulation results, it＇s clear that the applicaiton of the auto- matic calibration module of SWAT model in the Yunzhou reservoir basin is successful.
