| 摘 要： | 通过对流域进行离散处理,从集合论角度出发,将流域看成点的集合,对流域进行离散化处理,在其上对流域源点、交汇点、出口点、单径流及复合径流各流域要素进行约束和定义,提出并实现了算法。该算法基于流域水文模拟方法,较好地解决了流域出口点和环流判别问题,使追踪出的径流更符合实际,具有简单、高效、实用的特点。根据算法设计开发了软件系统,并且应用到黄土丘陵沟壑区小流域分布式水文和侵蚀预报模型中,取得了较好的模拟效果。

| Abstract: | By means of discrete processing to the small watershed,the source,confluence point,outlet,single runoff and junction runoff was defined based on elements of set theory.And the algorithm to simulate the hydrology and erosion prediction in watershed was proposed.The algorithm solved the problem of outlet and circulation determinant which were the difficulty of current commercial software.The algorithm have simple,effective and practical characteristic.The application of the method to Loess hilly-gully regions... |
