摘要
参数率定是水文模型的重要研究内容,简单高效的参数率定方法能提高模型应用效率,促进模型推广。以淮河大坡岭流域为研究对象,基于VIC模型参数敏感性分析结果,将系统微分响应参数率定方法(System Response Parameter Calibration Method,SRPCM)应用于VIC理想模型和实际模型的参数率定,探究该方法在大尺度分布式水文模型中的应用效果。结果表明:将SRPCM应用于VIC模型具有一定的可行性和高效性;建立的VIC模型能较好地模拟大坡岭流域的日径流过程,率定期和验证期的平均纳什系数均达到0.6,径流总量相对误差均在8%以内。所以,SRPCM是一种有效的VIC模型参数率定方法。
Parameter calibration is an important research content of hydrological model.The application of simple and efficient parameter calibration method can enhance the efficiency and promote the popularization of the model.In order to explore the application effects of the System Response Parameter Calibration Method in large-scale distributed hydrological models,SRPCM is applied to calibrate the parameters of VIC ideal model and actual model in Dapoling Catchment,based on the sensitivity analysis of parameters.The results in this study indicate that it is feasible and efficient to apply SRPCM to the VIC model;the VIC model is able to simulate the daily runoff in Dapoling Catchment effectively;the average Nash coefficients exceed 0.6 and the relative errors of runoff volume are below 8%during the calibration and validation periods.Therefore,SRPCM proves to be an effective and useful parameter calibration method.
