基于生态完整性和社会服务功能的岳城水库健康评估

Health assessment of Yuecheng Reservoir based on ecological integrity and social service function

基于生态完整性和社会服务功能对岳城水库健康状况进行评估,构建了水文水资源、物理结构、水质、生物和社会服务功能5个准则层18个指标的指标体系,采用分级指标评分法,逐级加权,综合评分,得出岳城水库健康指数为69.2,属于健康状态。5个准则层中生物、水文水资源、水质3个准则层健康指数偏低,因此应充分重视岳城水库的生物多样性、上游来水水量和水质以及水体富营养化状况等。

The Lake health index of Yuecheng Reservoir is evaluated based on the ecological integrity and social service functions.And an index system of 18 indicators is constructed,which belongs to five criteria layers of hydrology and water resources,physical structure,water quality,biological and social service functions.Gradual weighting and comprehensive scores show that the Yuecheng Reservoir Health Index is 69.2,which is a healthy state.The health index of biological,hydrologic and water resources and water quality in the five criterion layers is relatively low.Therefore,it is important to pay full attention to the biodiversity,upstream inflow and quality and eutrophication status of Yuecheng Reservoir.
