摘要
本文结合城市湖泊生态系统的特点,利用OECD(联合国经济合作开发署)建立的压力-状态-响应(PSR)框架模型建立指标体系,将信息熵(IE)理论引入指标权重的确定,建立了城市湖泊生态系统健康评价模型,选用综合健康指数法(CHIM)进行城市湖泊生态系统健康评价,并应用山东省聊城市东昌湖的实测资料,对其生态系统健康状况进行了评价,评价结果与实际情况基本相符。
Combining with the characteristics of urban lake ecosystem,the index system for its health assessment was built with the PSR（Pressure-State-Response） conceptual model（built by OECD）.The index weights were determined with information entropy theory.The comprehensive health index method was used to assess health state of urban lake ecosystem.The application of comprehensive health index method in Dongchang Lake was given as a case.The states of its ecosystem health were assessed.The results conform basically to reality.
