| 摘 要： | HEC模型将水文模型同地理信息系统结合，同以往的水文模型相比，HEC模型更加直观和简洁。该模型以ARCVIEW为操作平台，通过对数字高程模型(DEM)的处理，完成对流域特征数据的提取，生成水系和流域边界。在参数率定中采用了最优化方法的理论，通过不同的目标函数，找到流域参数最优值。通过在漳卫南流域的应用，表明该模型使用方便，结果精度高。

| Abstract: | HEC model combines the hydrological model with gographical information system, it is visualer and succicter than hydrological models in the past. This model takes ARCV EW as platform, collects the characteristic data of basin and produces the water system and the drainage area boundary by means of DEM treatment. The optimization theory is adopted in the determination of parameters. The optimum value of basin parameters is found by means of different objective functions. The application of this model in Zhang weinan basin indicats that the utilixation of this model is convenient, the precision of result is high. |
