流域水系统典型分区方法对比分析及应用

为了合理开发利用和保护流域水资源,分别介绍了三种典型流域分区方法的研究现状,从分区目的、分区特色、分区结果的应用和分区主导因素等方面对三种分区方法进行了对比分析,并将三种分区方法应用于沙颍河流域中。结果表明,水资源分区将沙颖河流域分为六个单元;水功能区划划分了沙颖河流域主要河流;水生态区划将沙颖河流域分为五个单元。研究结果可为沙颍河流域水资源保护政策的制定提供指导,也可为其他中小型流域的分区工作提供借鉴。

Comparative Analysis and Application of Typical Zoning Methods in the Study of River Basin Water System

In order to rationally utilize and protect water resources of river basin, this paper introduces the research status of three kinds of typical watershed zoning method. And then the three methods in the goal of zoning, feature, application results and the dominant factors were comparative analysis, respectively. Finally, the three zoning methods were applied in Shaying River Basin. The results show that the water resources partition of Shayinghe basin can be divided into six units; water functional zoning regionalizes the main rivers of Shayinghe basin; water ecological regionalization of Shayinghe basin can be divided into five units. The research results can not only provide the guidance for the formulation of water resources protection policy in Shayinghe Basin, but also the reference for other small watershed.
