中文摘要：

以汾河上游流域为研究对象,用宁武、静乐、岚县、娄烦和古交等气象站和水文站2000到2011年间的气象、水文等资料,结合DEM数据、LUCC数据、土壤空间分布,构建汾河上游水文模型.应用LH-OAT法对其进行参数敏感性试验,应用SUFI2法和手动调参相结合的方法对模型参数进行率定和验证,然后进行径流模拟.结果表明,在模型率定与验证期,除了2006-2011年干季,受汾河上游头马营引黄调水影响,使其模拟值与实测值相比偏小以外,总体来说模拟与实测径流的Nash-Sutcliffe效率系数分别为0.78和0.79,相对误差为5.8%和8.7%,均小于10%,径流量和降水等指标对于土地利用/覆被变化比较敏感.SWAT模型在汾河上游模拟效果较好,有较强的适用性.

英文摘要：

This paper selected the upper reaches of Fenhe basin as study area,combined with Ningwu,Jingle,Lanxian,Loufan,Gujiao and Fenhe station meteorology data,precipitation and runoff data,land use,soil data,and DEM data,and used SWAT model to simulate runoff.The LH-OAT method was used to analyze model parameter sensitivity,respectively.The calibration and validation of SWAT were performed on a monthly basis using both SUFI2 and manual operation method.The result showed that in addition to in the dry season between 2006 and 2011,the simulation value was smaller than measured value due to the influence of Yellow River water in the Toumaying.relative error（Re） was 5.8% and 8.7%,less than 10% and Nash-Sutcliffe simulation efficiency（Ens） values was 0.78 and 0.79 for the calibration period and the validation period in Fenhe river basin.The result also indicated runoff and precipitation were more sensitive for LUCC,the SWAT model has good performance in Fenhe River basin.
