摘要
为了更好地对修河流域水资源进行科学合理的规划与评价,以修河干流虬津站断面以上控制流域为研究区域,构建修河干流流域大尺度分布式VIC模型(Variable Infiltration Capacity,VIC model),利用普林斯顿气象同化数据集驱动模型进行流域的径流模拟研究,以纳什效率系数NSE和相对误差Er两个评价指标并结合修河干流下游虬津站多年实测月均流量资料进行模型的的率定与验证。研究结果表明:在月尺度上,率定期和验证期的Nash效率系数分别为0.85、0.84,相对误差分别为8.67%、8.98%。模型的构建和研究结果可为研究流域的水循环和水资源规划评价提供一定参考依据。
In order to better plan and evaluate the water resources of the Xiuhe River Basin in a scientific and reasonable manner,the control basin above the section of the Qiujin Station on the main stream of the Xiuhe River is used as the research area to construct a large-scale distributed VIC model(Variable Infiltration Capacity,VIC).By using the Princeton meteorological assimilation data set to drive model to carry out the runoff simulation study of the river basin,using two evaluation indicators,the Nash efficiency coefficient NSE and the relative error Er,combined with the measured monthly average flow data of the Qiujin Station in the downstream of the Xiuhe River to calibrate and verificate.The research results show that on a monthly scale,the Nash efficiency coefficients of the regular rate and the verification period are 0.85 and 0.84 respectively,and the relative errors are 8.67%and 8.98%respectively.The research results provide a certain reference basis for the planning,evaluation and management of water resources in the study area.
