基于 Sobol 方法的新安江模型参数敏感性分析
Sensitivity Analysis of Xinanjiang Model Parameters using Sobol Method
摘要
Abstract
Sensitivity analysis was performed to analyze the inputs and outputs of the complex model and system qualitatively and quantitatively ,which can benefit the inspection of model structure ,identification of model parameters ,and model application .In this paper ,Sobol method was applied to evaluate the sensitivity of single parameter and multiple parameters of the model in the Huanren reservoir catchment .The objective functions of sensitivity analysis included the deterministic coefficients and error co-efficients of total water ,low flow ,and high flow .The results showed that the sensitivity of parameters was different under dif-ferent objective functions ,and Sobol method can provide the sensitivity for all parameters and sensitivity between each parame-ter ,which is useful for sensitivity analysis of hydrological models .关键词
