锦州湾海域生态系统健康状况评价

摘要

基于结构功能指标体系评价法,利用层次分析法构建锦州湾海域生态系统健康评价指标体系,并选择2005-2009年8月生态调查数据对其进行初步的定量评价.结果表明,可以通过海洋化学指标、生态学指标和社会经济学指标三大类33个指标来建立锦州湾生态系统健康评价指标体系；2005-2009年8月锦州湾生态系统的整合健康指数依次分别为1.01、1.90、2.00、1.45和1.10,均低于系统健康指数值2,锦州湾海域生态系统连续5年一直处于亚健康状态,且从目前海域的污染现状来看,这一海域的水质、沉积物和生物体污染均比较严重,要修复其生态功能需要投入巨大的物质和能量.%On the basis of structural and functional indicator system and of Analytic Hierarchy Process(AHP),ecosystem health of the sea areas in Jinzhou Bay was primarily assessed underlying the ecological survey data in August from 2005 to 2009.The indicator system for ecosystem health assessment of Jinzhou Bay can be established by three types of marinechemical,ecological and socio-economic indicators with 33 indicators.The result showed that the value of integrated health indicator of Jinzhou Bay ecosystem (IHI) were 1.01,1.90,2.00,1.45 and 1.10 in August from 2005 to 2009 respectively,which were lower than systematic health value 2.It showed that,Jinzhou Bay ecosystem was subhealthy in the past five years.On the situation of pollution,water quality,marine sediments and organism are rather seriously polluted in Jinzhou Bay.Therefore,it needs much endeavors to restore the sea areas to be healthy with lots of material and energy.
