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。
In order to reasonably develop and utilize the water resources of the basin, the author introduced the research status of the three typical basin zoning methods respectively, and compared and analyzed the three zoning methods in terms of zoning purpose, zoning characteristics, application of zoning results and zoning dominant factors, Three zoning methods were applied to the Shaying River Basin. The results show that the water resources division divides the Shaying River Basin into six units; the water functional division divides the main rivers in the Shaying River Basin; and the water ecological division divides the Shaying River Basin into five units. The results can provide guidance for the formulation of water resources protection policies in the Shaying River Basin and provide reference for the zoning work of other small and medium-sized river basins.
