几种典型流域水文模型类比分析

Several typical watershed hydrological models and their comparisons

流域水文模型是研究水文自然规律和解决水文实际问题的重要理论基础。按照流域水文模型的基本分类,简单总结分析了国内外几种典型流域水文模型的基本建模思路、适用范围及其优缺点等。在此基础上,以模型效果评价指标为准则,通过对同一流域上不同模型、以及同一模型在不同流域上的应用效果进行类比和分析,提出了在特定流域应该选取比较适用的水文模型以及几种典型水文模型的最佳适用流域。

Watershed hydrological model is the most important academic basis for learning the hydrological natural rule and solving the problems in hydrological practices. According to the basic classes of watershed hydrological models, simply summarized and analyzed several typical hydrological models at home and abroad, and studied the basic process of modeling, range of use, advantages and disadvantages and so on. At the base of research, taking the model efficiency estimate index for guide line, collecting the application results of different typical models on a same basin and a same typical model on different basins to do some comparison, and indicated that selected proper hydrological model for a given basin, and also chosen the suitable basins for several typical hydrological models.
