为对黄泥庄流域水资源进行评价与规划,探讨VIC大尺度分布式水文模型在中小尺度流域上的适用性,采用VIC模型对黄泥庄流域的径流进行模拟,结果表明:VIC模型在黄泥庄流域具有较好的适用性,说明VIC大尺度水文模型在中小尺度流域具有一定适用性;月径流模拟的Nash-Sutcliffe效率系数均在0.80以上,相对误差大部分在0.10以内,满足该流域水资源评价与规划的要求;模拟过程中部分较大洪峰,VIC模型的径流模拟效果稍显欠佳,参数率定结果的不确定性也给模拟结果带来一定误差,需进一步研究改进。
為對黃泥莊流域水資源進行評價與規劃,探討VIC大呎度分佈式水文模型在中小呎度流域上的適用性,採用VIC模型對黃泥莊流域的徑流進行模擬,結果錶明:VIC模型在黃泥莊流域具有較好的適用性,說明VIC大呎度水文模型在中小呎度流域具有一定適用性;月徑流模擬的Nash-Sutcliffe效率繫數均在0.80以上,相對誤差大部分在0.10以內,滿足該流域水資源評價與規劃的要求;模擬過程中部分較大洪峰,VIC模型的徑流模擬效果稍顯欠佳,參數率定結果的不確定性也給模擬結果帶來一定誤差,需進一步研究改進。

This research was aimed to contribute to water resources evaluation and planning in Huangnizhuang River basin. Furthermore,it was aimed to explore the applicability of VIC macroscale distributed hydrological model in mesoscale or smaller-scale basins. The applicability of VIC model in runoff simulation in Huangnizhuang River basin was studied. The result shows that the VIC model performs well in Huangnizhuang River basin;the VIC model can be used in mesoscale watershed. The Nash-Sutcliffe efficiency of monthly runoff simulation is all above 0. 80. The relative errors of monthly runoff simulation are almost within 0. 10. It can meet the requirements of water resources evaluation and planning in Huang-nizhuang River basin. However,VIC model is not good enough to simulate some large peaks. In addition,the uncertainty of calibration algorithm results can cause some errors in runoff simulation. Thus,more study and improvement should be carried out.
