| 摘 要： | 由于平原河网区地势平坦,地形起伏较小,SWAT模型在对平原河网区进行河流生成和子流域划分时往往不能反映河流的真实情况,经常会出现所生成河流不连续的现象.针对此技术问题,提出了"分片区、分层次"的河流生成和子流域划分方法,可以解决SWAT模型在平原区河流生成和子流域划分困难的问题,生成的子流域和河流与实际情况比较接近并可以对河流生成和子流域划分进行"局部加密".将"分片区、分层次"方法应用于温瑞塘河流域,取得了不错的效果.

| Abstract: | The terrains of plain regions with river systems are usually flat,and the SWAT model is not able to delineate the sub-basins or generate river lines effectively in these areas.Instead,the generated river lines by SWAT model in the plain areas are usually unconnected.In this study,a partition-based and hierarchical method of generating river lines and delineating the sub-basins by SWAT model has been experimented,in order to provide support for SWAT's application to net-river basins.By using this method,the ... |
