半干旱半湿润地区流域产流模型分析与比较

Comparation and Analysis on Runoff Models in Semi-dry & Semi-humid Region

根据半干湿地区的特点,介绍并分析了流域综合产流模型,将它与蓄满产流模型在模型的建立上进行了分析和比较;并把这个模型应用到半干湿的文峪河流域,使之与蓄满产流模型的计算结果进行比较,结果表明:流域综合产流模型从结构和应用上更适合于半干湿地区;究其原因:综合产流模型所描述的产流规律是超渗与蓄满的结合,降雨率大于入渗率便产流,随着入渗量的累计,又使得流域逐渐蓄满。

According to semi-dry and semi-humid characteristics, this paper introduced and analyzed a integrated model of runoff generation of watershed. Applying this model to seml-dry and semi-humid Wenyu river watershed and compared calculation outcome to storage full model of runoff, it was suggested and concluded that the integrated model of runoff generation more suitable for semi-dry and semi-humid region from structures to applying.
