Title: The Aquatic Ecosystem Health Assessment of Typical River Aquatic Eco-functional Zones in the North of Liaoning Province
Abstract:The 11third-level aquatic eco-functional zones of Qinghe River and Fanhe River Basins in the North of Liaoning Province are selected as the basic evaluation units in this paper.The analytic hierarchy ...The 11third-level aquatic eco-functional zones of Qinghe River and Fanhe River Basins in the North of Liaoning Province are selected as the basic evaluation units in this paper.The analytic hierarchy index system of aquatic ecosystem health assessment is constructed in accordance to the characteristics and connotation of aquatic ecosystem health and the ecological features of the research areas.The Improved Analytic Hierarchy Process(IAHP)and Fuzzy Mathematics Model are adopted to evaluate the aquatic ecosystem health of Qinghe River and Fanhe River Basins.The assessment results indicate that among the four third-level aquatic eco-functional zones of Fanhe River Basin,three of them are in thehealthystate(IV-5-2,IV-5-3,IV-5-4)and one is in the normal state(IV-5-1).Among the seven third-level aquatic eco-functional zones of Qinghe River Basin,one is in thehealthystate(IV-5-11),two are in the sub-healthy state(IV-5-10,IV-5-12),two are in the normal state(IV-5-9,IV-5-13),and two are in the unhealthy state(IV-5-8,IV-5-14).The aquatic ecosystem health assessment combined with the scientific assessment model and the aquatic eco-functional zones can provide a scientific basis for the comprehensive ecological treatment in river basins.Read More
