基于ArcGis10.0建立了锦江流域数据库,将ArcSWAT2009模型应用于锦江流域的径流模拟。采用LH-OAT灵敏度分析方法进行参数灵敏度分析,得出模型灵敏参数序列,并利用4个水文站(危坊、宜丰、上高、高安)2001~2008年径流观测数据对SWAT模型进行参数率定。模型适用性评价结果表明:校准期和验证期年均值相对误差(Re)小于20%,月相关系数(R2)和月效率系数(NSE)均大于0.7,拟合精度较高,SWAT模型适宜锦江流域的径流模拟。
基于ArcGis10.0建立瞭錦江流域數據庫,將ArcSWAT2009模型應用于錦江流域的徑流模擬。採用LH-OAT靈敏度分析方法進行參數靈敏度分析,得齣模型靈敏參數序列,併利用4箇水文站(危坊、宜豐、上高、高安)2001~2008年徑流觀測數據對SWAT模型進行參數率定。模型適用性評價結果錶明:校準期和驗證期年均值相對誤差(Re)小于20%,月相關繫數(R2)和月效率繫數(NSE)均大于0.7,擬閤精度較高,SWAT模型適宜錦江流域的徑流模擬。

The database of Jinjiang River Basin was established on the basis of ArcGis 10. 0 and the ArcSWAT 2009 was ap-plied in the runoff simulation of this Basin. The sensitivity of the parameters was analyzed using LH-OAT method and the sensi-tive parameters series of the model were obtained. The parameters were rated using annual runoff data of 4 hydrological stations (Weifang, Yifeng, Shanggao, Gao’an) from 2001 to 2008. The result of applicability evaluation shows that the relative error ( Re ) in calibration period and validation period is less than 20%, the coefficient of correlation ( R2 ) and Nash-Sutcliffe co-efficient of efficiency ( NSE ) are larger than 0. 7. Therefore, the fitting precision is relatively higher and the SWAT model is suitable for the runoff simulation of Jinjiang River Basin.
