太湖流域湖西山丘区小流域水文模型适用性研究

Research on the applicability of hydrologic models in hilly areas of Huxi District in Taihu Basin

选取太湖流域湖西山丘区具有代表性的洛阳河流域,收集了2016—2017年的实测洪水资料,采用API水文模型、新安江模型和太湖流域水文模型进行洪水模拟,分析各模型的适用性和模拟精度。研究表明,各模型在洛阳河流域的适用性较好,均取得了良好的效果,其中新安江模型模拟精度总体优于API模型和太湖流域水文模型,为湖西山丘区其他小流域的洪水模拟提供了参考。

The Luoyang river watershed,a representative part of the hilly areas of Huxi District in Taihu Basin,was selected to collect the measured flood data from 2016 to 2017.The API hydrological model,Xin'an river model and Taihu basin hydrological model were used for flood simulation to analyze the applicability and simulation accuracy of each model.The results showed that the models all had good applicability in Luoyang river watershed.The Xin'anjiang model performed better than API model and Taihu hydrological model,which provided a reference for flood simulation of other watersheds in hilly areas of Huxi district.
