摘　　要：为验证新安江模型参数敏感性，以梁辉水库为例，采用2002-2006年连续5年的逐日水文资料进行日模和次洪模拟，并通过计算及对比分析率定较敏感的参数。结果表明，选择模型的敏感性参数有助于新安江模型率定及资料缺失地区推广使用，为流域水文模拟提供参考。In order to study the sensitivity of parameters of the Xin＇anjiang Model, Xin＇anjiang Rainfall-runoff Model was applied to Lianghui Reservoir with the precipitation and evaporation data from 2002 to 2006. Both the daily runoff and flood event runoff were calculated. The sensitivity of parameters are generated by calculation and analysis. The results show that the sensitivity analysis of the model parameters is not only very essential for model test hut Mso very useful for the further application of Xin＇anjing Model in either the gauged or the ungauged catchments.
