摘要
Abstract
By taking 10 flood events occurred in Shanxi Province as the study objects,the sensitivities and correlations of the pa rameters of the double-excess runoff generation model under the conditions of different watersheds,different flood grades and multi-objective functions are obtained with the optimized LH-OAT method through changing the parameter orientations at first,and then the comprehensive sensitivity coefficients of the model parameters are determined.The study result shows that the sensitivities of the parameters of the double-excess runoff generation model are impacted by the objective functions and the characteristics of watersheds,and only when the objective function becomes PE,the sensitivities and correlations between it and all the parameters are not so obvious.The improved entropy method can qualitatively and quantitatively analyze the comprehensive sensitivities of the model parameters under the condition of multi-objective function,while the order of the comprehensive sensitivities of the model parameters is Sr ＞ Ks ＞ b ＞ α0 ＞ r ＞ c.关键词
