摘要：

水生态功能分区是实现流域水环境“分区、分级、分类、分期”管理的基础。以高程、干燥度及年均径流深为一级分区指标，土地利用、土壤类型、坡度、人均GDP为二级分区指标，将丹江口水
源区分为6个一级水生态功能区和19个二级水生态功能区。比较不同分区的水生境状况及底栖动物种群结构特征，发现一级分区间的水生境状况与底栖动物种群结构均存在差异，二级分区之间虽然有部分
生境指标较为接近，但底栖动物种群结构差异明显，证明了分区方案的科学性和合理性，为水源区的生态系统保护和水资源管理提供了依据。

Abstract:

Delineation of aquatic ecoregion is the foundation of“zoning, grading, staging and classification”management of water environment in river basin．With the elevation,
drought degree, the average annual runoff as the level I delineation indicator, land use, soil type, slope, the per capita GDP as the level II delineation indicator, the water
source area of the Danjiangkou Reservoir was divided into 6 level I aquatic ecoregions and 19 level II aquatic ecoregions. Comparison of different ecoregions in aquatic habitat conditions and community structure of zoobenthos, significant differences were found. Though some habitat indicator was similar between different second ecoregions, there were
significant differences in the community structure of zoobenthos, which suggests that the delineation scheme is scientific and reasonable, and should be a good idea for the cosystem protection and water resources management of the water source area of the Danjiangkou Reservoir.
Key words：aquatic ecosystem; ecological function regionalization; water resource; water source area of Danjiangkou
