| 摘 要： | 首先构建一个以自然子流域为计算单元的分布式水文模拟系统,每一个计算单元内,利用土壤水蓄水容量曲线表示张力水的空间分布,在单元之间,认为坡度大的单元土壤层厚度和蓄水容量小,同样的降雨先产流。通过建立计算单元蓄水容量与地形坡度间的关系,考虑了地形坡度对产流的影响。在淮河流域上游大坡岭流域的应用结果表明,所用方法得到了理想的模拟结果。

| Abstract: | A distributed hydrologic modeling system was developed in which sub-basin is used as unit area.In each sub-basin,the soil moisture storage capacity curve is used to represent the spatial distribution of tension water.It is thought that the soil thickness and soil moisture storage capacity of greater slope sub-basin is smaller so that runoff production appears first.In order to take account of the affect of slope on runoff production,the relation between soil moisture storage capacity of sub-basin and slope ... |
