摘　　要：产流计算是水文模拟的关键环节之一,不同的水文模型中,产流计算方法多样。采用几种降水入渗产流模型在珠江流域赤溪水文站建立模拟模型,通过"06.7"特大洪水实测资料对各个模型的参数进行优选,经过模拟结果对比及参数敏感性分析,选出土壤蓄水特征法(SMA)与指数下渗法(Exponential)等2种最优产流模型;同时,传统的初损稳渗法也能达到较好的效果。Runoff calculation is one of the key links in hydrological simulation. In different hydrological models, there are many ways to calculate runoff. In this paper, several kinds of precipitation infiltration runoff models are used to establish the simulation model of the Chixi hydrological station in the Pearl River Basin. The parameters of each model are optimized by the data of 06. 7＂ flood, after the simulation results analysis and parameter sensitivity analysis, the best of two methods, Soil Moisture Accounting Model （SMA） and Exponential Model（ Exponential）, are found, in addition, the traditional initial infiltration method can achieve better results.
