摘　　要：近年来,城市生态问题日益突出,人与自然的矛盾不断恶化。以活力、组织结构、恢复力、服务功能、人群健康状况等5个要素构建城市生态系统健康评价指标体系,基于熵值法确定指标权重,运用模糊综合评价方法,对2005—2014年长三角16市的城市生态系统健康状况进行综合评价。结果表明:总体来看,长三角区域的城市生态系统健康水平逐年提高;从各市来看,绝大部分城市(如上海市、南京市等)的城市生态系统均处于亚健康状态,需要更长时间实现向健康状态的转变;少数城市(如南通市和台州市)有明显好转的迹象。未来,长三角区域要继续提升城市生态系统的健康水平,进一步调整组织结构,加强服务功能建设,提高人群生活水平。In recent years, the urban ecological problems have become increasinglyprominent, and the contradiction between men and nature is worsening. The health evaluationsystem of urban ecosystem is composed of five factors, namely vigor, organizational structure,resilience, service function, and population health status. Based on the entropy method andfuzzy comprehensive evaluation method, comprehensive evaluation of the urban ecosystemhealth status of 16 cities in the Yangtze River Delta from 2005 to 2014 is analyzed. The resultsshow that some improvements can be found in urban ecosystem from 2005 to 2014 while anoverwhelmingly majority of cities such as Shanghai and Nanjing City are still in sub-health stateswhich need longer time to step into health state, and a small part of the cities have improvedmarkedly such as Nantong and Taizhou city, etc. Further improvement still need to be seen inYangtze River Delta in future on the health status of urban ecosystem, the adjustment oforganizational structure, the construction of service function and the living standards of thepeople.
