摘　　要：新安江模型分水源计算时较多的待定参数往往会导致"异参同效"现象的发生,这样不仅使得率定出的参数可能不准确,而且给模型的使用带来不便。将流域出口的流量过程线进行径流分割,计算得到壤中水径流深。同时将壤中水径流深与分水源参数建立函数关系,从而利用流量过程线估算新安江模型分水源参数。以陕西省陈河流域为例,将估算出的分水源参数应用于新安江模型进行洪水模拟,并取得了良好的模拟结果。与传统的参数率定方法相比,本方法能够快速且较为准确地估算出新安江模型的分水源参数,减少了待率定的参数的个数,在一定程度上降低了异参同效对模型应用的影响。In this page, we obtain the depth of soil water runoff by investigating different runoff components. The functional relationship between the depth of soil water runoff and the parameters of runoff components can be establish with free water reservoir in the hill slope hydrology. Finally, the Chenhe catchment in Shanxi Province is taken as a typical basin. The application results in Chenhe catchment show that this method is effective. Compared to traditional methods, the method in this paper can estimate the parameters in water source partition rapidly and accurately. It can reduce the numbers of parameters which should be confirmed. And it may reduce the chance of equifinality for different parameters.
