| 摘 要： | 基于结构功能指标体系评价法,利用层次分析法构建长江河口生态系统健康评价指标体系,并选择2002年至2004年8月生态调查数据对其进行初步的定量评价.结果表明,可以通过物理化学指标、生态学指标和社会经济学指标三大类30个指标来建立长江河口生态系统健康评价指标体系;2002年至2004年8月长江河口生态系统的整合健康指数(IHIYRE)分别为3.09,3.17和4.36,均低于系统健康指数值(5),河口生态系统总体上处于健康与不健康之间(3≤IHIYRE≤5).而且,从目前河口海域的污染现状来看,这一海域的水体富营养化比较严重,且状态比较稳定,使其恢复到健康状态需要投入巨大的物质和能量.

| Abstract: | On the basis of structural and functional indicat or system and of Analytic Hierarchy Process (AHP),ecosystem health of the sea areas in the Changjiang River Estuary was primarily assessed underlying the ecological survey data in August from 2002 to 2004.The indicator system for ecosystem health assessment of the Changjiang River Estuary can be established by three types of physic-chemical,ecological and scio-economic indicators with 30 indicators.The result showed that the value of integrated health indicator of the Yangtze River Estuary ecosystem(IHIYRE)were 3.09,3.17 and 4.36 in August from 2002 to 2004 respectively,which were lower than systematic health value(5).It showed that,ingeneral,the Changjiang River Estuary ecosystem was located between healthy and unhealthy(3≤IHIYRE≤5).On the situation of pollution,the sea areas in the Changjiang River Estuary are rather seriously eutro phicated and the status is rather stable.Therefore,it needs much endeavors to restore the sea areas to be healthy with lots of material and energy. |
