摘　　要：采用投影寻踪模型,选取典型指标,利用基于实数编码遗传算法优化求取最佳投影方向,对福州市、厦门市和泉州市2007年的城市生态系统健康状况进行评价。结果表明:2007年,福州市、厦门市和泉州市对应的等级值分别为3.74、3.96和3.30,分别处于较健康、较健康和亚健康状态。结合指标体系,分析3个城市生态系统存在的不足之处,对实施可持续发展具有重要意义。A health assessment of urban ecosystem was conducted in Fuzhou,Xiamen and Quanzhou in 2007 by using a novel multi-indicator data processing method and projection pursuit model,in which the optimal projection direction was obtained based on real-rode genetic algorithm.The results indicated that the grade value of the three cities in 2007 were in a healthy,healthy and sub-healthy status respectively.In addition,the shortcomings in the three urban ecosystems were found out based on the assessment index systems.Such studies are significant for the implementation of sustainable development in cities in West Coast Economic Zone.
