摘要
利用集对分析方法，将评价城市生态系统健康状况的多个指标系统合成一个与最优评价集的相对贴近度，用来描述城市生态系统健康状况．运用集对分析方法，以北京、大连、上海、武汉、厦门、广州等城市为例，对1995～2003年间的城市生态系统健康进行了评价．结果表明，不同时期各城市生态系统健康状况排序有所变化，但厦门和广州一直名列前茅．此外，对北京1992～2003年间城市生态系统健康状况的变化情况进行了具体分析，结果显示，北京城市生态系统健康状况随着时间的推移而不断改善．
Set Pair Analysis Method（SPAM） was employed to assess the health of urban ecosystems. This assessment method led to dialectic and actual results beenuse it objeetively treats and systemntieally estimates the uneertainty of urban system. Multiple health indexes of urban eeosystems ean be eombined to form n relntive-elose-degree of urban eeosystem health to the optimal evaluation set, through SPAM. The urban eeosystem health of Beijing, Dalian, Shanghai, Wuhan, Xiamen and Gunngzhou from 1995 to 2003 were evaluated by using SPAM. It enn be eoneluded that the urban eeosystem health of Xiamen and Guangzhou eity was the best, while the order of the rest eities＇eeosystem health often ehanged with time. Moreover, the ehnnge of Beijing＇s urban eeosystem health from 1992 to 2003 was analyzed. It showed that Beijing urban eeosystem health had inereased in the period.
