探讨了苏州生态城市建设所取得的成就,将苏州生态城市建设现状与国家生态城市建设标准进行比较.在此基础上,根据苏州城市建设的实际情况,基于自然、经济、社会三大子系统构建城市生态系统的健康评价指标体系和标准,采用均方差法确立指标权重,对苏州2004～2008年的城市生态系统健康状况进行定量研究,探寻其生态城市建设中存在的关键问题.结果表明:苏州城市生态系统健康状况水平整体发展趋势较好,但三大子系统协调度处于中度协调状态,自然子系统面临严峻压力.%After the discussion of accomplishments of ecological urban construction in Suzhou City, the current ecological urban construction in Suzhou has been compared with the national standard for ecological urban construction. According to the actual situation of Suzhou urban construction, the health assessment index system and standards for urban eco-system have been established based on natural, economic and social sub-system. By using mean square deviation, indexes' weights have been identified. After the quantitative research on health condition of urban eco-system in Suzhou City from 2004 to 2008, it has found key problems existing in its ecological urban construction. The results show that Suzhou urban eco-system develops well in general, but the three sub-systems are coordinated moderately, and natural sub-system faces severe pressure.
