Comprehensive assessment on urban ecological system is one of important issues for regional sustainable development research. Urban eco-efficiency is the effective tool to integrate sustainabable strategies into the development planning and management initiatives, which expresses the relationship of inputs of ecological impact and outputs of social welfare. An evaluation model of urban sustainability based on eco-efficiency was proposed by integrating Ecological Footprint model and Human Development Index. Using this model, a case study of Xiamen City was carried out using the statistical data from 2000 to 2006. There is a fluctuation of ecoefficiency which showed a steady increase first, then a sharp decline and a marginal increase towards the end. During 2000-2006, the per-capita ecological footprint increases from 4.279 hm2 to 5.462 hm2; and the Human Development Index increases from 0.831 to 0.896; thus the eco-efficiency, resource efficiency and environmental efficiency declines by 15.5%, 15.7% and 15.3% respectively. Xiamen experiences sustainability hypo-increasing phase first, sustainability increasing phase secondly, then sustainability decreasing phase, and sustainability increasing phase in the end. On the whole, the urban sustainability shows a decreasing trend.
城市生态系统综合评估是区域可持续发展研究的重要课题之一。城市生态效率是将可持续发展战略融入发展规划和管理举措的有效工具，它体现了生态影响投入与社会福利产出之间的关系。通过整合生态足迹模型和人类发展指数，提出了一种基于生态效率的城市可持续性评估模型。利用该模型，以2000年至2006年的统计数据对厦门市进行了案例研究。生态效率存在波动，先是稳步上升，然后急剧下降，最后略有上升。2000 - 2006年期间，人均生态足迹从4.279公顷增加到5.462公顷；人类发展指数从0.831提高到0.896；因此，生态效率、资源效率和环境效率分别下降了15.5%、15.7%和15.3%。厦门先是经历可持续性低增长阶段，其次是可持续性增长阶段，然后是可持续性下降阶段，最后又是可持续性增长阶段。总体而言，城市可持续性呈下降趋势。
