水库型水源地水生态健康评价体系构建与应用

Construction and application of water ecological health evaluation system in reservoir water source area

在浙江省现行饮用水源地评价方法及国内外河流水生态健康评价实践的基础上,采用指标体系法,围绕“浙江省水库型水源地水生态健康综合指数”总目标,从水资源、水环境、水生物、水生境和水管护5个维度筛选了20项具体评价指标,建立了面向水库型水源地的水生态健康评价体系,并根据建立的体系对3处典型水库型水源地进行分析评价,结果表明3处水源地的水生态健康状况总体较好,但在水生生物多样性恢复、水库库区及周边生境修复等方面仍存在明显短板。

Based on the current evaluation methods of drinking water sources in Zhejiang Province and the practice of river water ecological health evaluation at home and abroad,Zhejiang province adopted the index system method and selected 20 specific evaluation indexes from the five dimensions of water resources,water environment,aquatic organisms,water habitat and water pipe protection around the general goal of"comprehensive index of water ecological health of reservoir water sources in Zhejiang Province",the water ecological health evaluation system for reservoir water sources is established,and the three typical reservoir water sources are analyzed and evaluated according to the established system.The results show that the water ecological health status of the three water sources is generally good,but there are still obvious shortcomings in the restoration of aquatic biodiversity,the restoration of reservoir area and surrounding habitats.
