将集对分析方法引入城市生态系统健康评价，结合多个健康指标，计算城市生态系统健康对最优集的近似程度，描述城市生态系统的健康水平。在此基础上，利用集对分析方法对北京、大连、上海、武汉、厦门和广州1995 ~ 2003年的城市生态系统健康水平进行了评价。结果表明，研究期间厦门和广州的城市生态系统健康状况最好，其他城市生态系统健康状况随时间变化。特别是对1992 ~ 2003年北京城市生态系统健康的变化进行了详细的分析。
Set pair analysis (SPA) is introduced to assess the urban ecosystems, through which the approximate degree of urban ecosystem health to the optimal set is calculated to describe the health level of the urban ecosystems by combining multiple health indices. The urban ecosystem health levels of Beijing, Dalian, Shanghai, Wuhan, Xiamen and Guangzhou from 1995 to 2003 are thereafter evaluated using SPA. The results show that the urban ecosystem health states of Xiamen and Guangzhou is the best during the study period, while the health states of the others changes over time. Particularly, the change of Beijing’s urban ecosystem health from 1992 to 2003 is analyzed in detail.
