建立抚河流域的SWAT-X模型,利用其敏感性分析模块分析参数灵敏度,得出4个敏感参数CN2、Gwqmn、rchrg_dp、ESCO;采用沙子岭、南城、廖家湾、娄家村4个水文站1998-2005年月数据进行水文参数率定并评价模型的适应性,结果表明径流模拟值均达到拟合精度(相对误差、相关系数、效率系数),SWAT-X模型适宜于抚河流域的径流量模拟.
建立撫河流域的SWAT-X模型,利用其敏感性分析模塊分析參數靈敏度,得齣4箇敏感參數CN2、Gwqmn、rchrg_dp、ESCO;採用沙子嶺、南城、廖傢灣、婁傢村4箇水文站1998-2005年月數據進行水文參數率定併評價模型的適應性,結果錶明徑流模擬值均達到擬閤精度(相對誤差、相關繫數、效率繫數),SWAT-X模型適宜于撫河流域的徑流量模擬.

Water yield and quality′s variation of Fuhe River,which is the second-largest tributary of Poyang Lake,play a very important role in water resource protection of Poyang Lake.SWAT-X model,as a new version of SWAT(Soil and Water Assessment Tool),was applied to Fuhe Basin for the runoff simulation.Four main sensitivity parameters(CN2,Gwqmn,rchrg_dp,ESCO) were obtained from sensitivity analysis module after SWAT-X model was set up.Based on the runoff monthly,which measured at Shaziling,Nancheng,Liaojiawan,Loujiacun hydrological station from 1998 to 2005,the calibration and validation of the model were carried out.The results showed SWAT-X could be used well in runoff simulation in Fuhe Basin because Re(relative error),R2(correlation coefficient) and Ens efficiency coefficient of the model were in the range of simulation accuracy standard.
