基于主客观赋权模糊综合评价法的湖泊水生态系统健康评价
Assessment of lakes ecosystem health based on objective and subjective weighting combined with fuzzy comprehensive evaluation
摘要
Abstract
This study investigated 37 lakes of the Jianghan lake group in the middle reach of the Yangtze River.Trophic state index(TSI)was applied to define the trophic status of the lakes.According to water quality,sediment quality and aquatic biological communities,the analytic hierarchy process(AHP)and entropy weight method combined with fuzzy comprehensive evaluation based on fuzzy mathematics methods were applied to evaluate the aquatic ecosystem health.The lakes trophic evaluation showed that Lake Haikou was in the mesotrophic status,18 lakes were in eutrophic status,and 18 lakes were in hyper-eutrophic status.The assessment of lake ecosystem health turned out that only Lake Haikou was in the "high" health status.Five lakes were in "good" health status: Lakes Dongxicha,Huama,Liangzi,Tongjia and Zhangdu.The rest 31 lakes were all in "poor" health status.According to the TSI,for the ecosystem health assessment of the Jianghan lake group,AHP combined with fuzzy comprehensive evaluation was proved to be a better method than the entropy weighting method.关键词
