现行几个主要产流模型的剖析

目前广泛应用的几个主要产流模型各有特点，但以往对它们的综合比较及其相互关系研究得不多，从而造成了用户选择模型的困难。通过深入剖析与对比，搞清了这几个模型之间的联系与区别，以及应用中需要注意的问题，一般情况下，应优选用综合产流模型。

Analysis of the Main Runoff Yield Models

Each of the main runoff yield models (the natural storage model, the model of combining the infiltration curve with the areal distribution curve of the infiltration capacity within the basin, and the compound model), widely applied in China now, has its own distinguishing features. But there are few papers about the comprehensive comparison of them and the relations among them. This causes the difficulties for users to choose the proper model. Therefore, the relations and differences of these models are thoroughly analyzed and compared, and the problems to be noticed in practice are also pointed out. Generally speaking, the compound model of runoff yield should be selected and applied first.
