水文模型参数敏感性分析方法研究评述

Comment on Parameter Sensitivity Analysis of Hydrological Model

参数敏感性分析一直被认为是用来确定模型关键参数、控制模型效率非常有效的过滤工具。同时,参数敏感性分析可以帮助理解模型结构,乃至发现模型结构缺陷,从而改善模型结构。本文详细归纳了典型的参数敏感性分析方法及其求解过程,讨论了各个方法的利弊,并对参数敏感性分析方法在水文模型中的应用前景进行了展望。

Parameter sensitivity analysis of hydrological model has been considered as an effective filtering tool to determine the key parameters,which can control model efficiency.At the same time,sensitivity analysis also can help to understand model struc-ture,and then find out the defects,so as to improve model structure.This paper summarized the parameter sensitivity analysis method and the concerned solving process,discussed the advantages and disadvantages,and prospected the future application of parameter sensitivity analysis method in hydrological models.
