| 摘 要： | 介绍了TOPMODEL的基本结构与理论。该模型结构简单、物理概念明确、优选参数少,在集总式和分布式流域水文模型之间起到了一个承上启下的作用。TOPMODEL在国外已被广泛研究,并认为是一个相当成功的流域水文模型。为了进一步拓宽该模型的应用,选择6个不同尺度、分布于不同区域和不同气候条件下的流域来应用研究该模型的径流模拟效果。结果表明,该模型在率定和校核两个阶段的模拟精度都比较高,基本上能达到新安江三水源模型的水平。

| Abstract: | The basic concepts and structure of TOPMODEL are introduced in this paper.As a bridge between the conceptual and the distributed models TOPMODEL has a simple structure clear physical explanation of water movement mechanisms in the watershed and a parsimonious number of parameters.In order to broaden the use of TOPMODEL in simulating watershed runoff in practice the hydrological data of six different watersheds are selected to test TOPMODEL.These six watersheds are located in different regions with different areas and of different climate conditions.For the purposes of comparison the Xinanjiang model is also applied on these watersheds in simulating runoff.It was found that TOPMODEL can succeed in simulating the watershed runoff in nearly every watershed and it is also comparable to the Xinanjiang model in terms of the model efficiency.It is strongly suggested that TOPMODEL be studied and appliedmore extensively in China. |
