摘　　要：为了提高新安江模型在喀斯特地区的模拟精度,以贵州独木河流域为研究对象,使用新安江模型对该流域进行了径流模拟研究.根据模拟分析结果和岩溶地区独特的水文特征,提出了改进新安江模型的3种设想,并对第1种设想(3层蒸散发结构改为2层蒸散发结构)进行了验证.对比分析结果表明,改进后模拟结果的平均确定性系数比改进前的高0.02,改进后的新安江模型可供类似地区的径流分析借鉴.In order to improve the simulation precision of the Xin＇ anjiang model in karst areas, the model was used to simulate runoff in the Dumu Watershed for a case study. According to the simulation results and the distinguishing hydrological characteristics of karst areas, three assumptions were proposed to improve the Xin＇anjiang model. The first assumption, that is, that the three-layer evapotranspiration structure is changed to a two-layer one, was verified. The comparison results show that the average coefficient of determination of the improved model was 0.02 higher than that of the unimproved model, and the improved model could be＇ used to analyze runoff in similar regions.
