城市生态系统生态化综合评价--以长三角为例

A Comprehensive Evaluation on Urban Ecosystem of Changjiang Delta

在分析城市生态系统组成的基础上,讨论了城市生态系统生态化的内涵;采用层次结构模型构建了城市生态化评价指标体系;采集了长三角地区具有代表性的八城市2004年的相关数据,运用因子分析与层次分析相结合的方法,对其经济、社会、环境子系统及复合生态系统的发展状况进行了综合评价,结果表明:长三角八城市的生态化水平排序依次为苏州、上海、宁波、南京、杭州、无锡、常州、扬州。

As the most developed district of China, Changjiang Delta is regard as the sixth Megalopolis. At present, lots of studies were performed on socioeconomic development of Changjiang Delta while economic-social-environmental comprehensive system is neglected. Based on the analysis on the constitution of urban ecosystem, the concept of ecologization was discussed and the urban ecologization index system was set up with the hierarchical architecture model. Then the index data of the eight cities which have representation in Changjiang Delta were collected, and comprehensive evaluation on the urban economic-social-environmental comprehensive system was carried out. Result indicated that the sequence of ecologization from the high to low was Suzhou , Shanghai, Ningbo, Nanjing, Hangzhou, Wuxi, Changzhou and Yangzhou.
