Ecosystem Health Evaluation of Haizhou Bay Marine Ranching
摘要
Abstract
The ecosystem health evaluation of marine ranching is the basis for marine ranching ecology protection.This paper used Analytic Hierarchy Process (AHP)which took water quality environment,biological resources and external pressures as guidelines layers and the eleven factors as the index layer to accomplish the ecosystem health evaluation of the Haizhou Bay marine ranching.The main conclusions are as follows.(1)Among guidelines layer,water quality envi-ronment has the most significant impact on the target layer with the weight of 0.65,followed by the biological resources (weight 0.28),and minimum influence is from the external pressures(weight 0.07).Among the indices layer,the dis-solved oxygen has the highest weight of 0.2016,followed by the phytoplankton(weight 0.1568).The least impact is from cold wave (weight 0.002)followed by the Nitrite(weight 0.007).(2)The comprehensive evaluation index (CEI) of ecological system of marine ranching of the Haizhou Bay is 0.68,and the ecological health condition rating is moder-ate.So it needs to further strengthen the ecological protection measures and ensure the sustainable development of marine ranching.关键词
