摘　　要：采用生态系统健康理论,根据评价信息的不确定性,提出应用未确知测度模型来评价和辨析城市生态系统健康问题,并结合城市复合生态系统特征,建立包含经济-自然-社会三个亚系统的城市生态系统健康评价指标体系。以浙江省9个城市为例,评价它们生态系统健康水平,得出杭州、宁波、绍兴处于健康状态,其它城市则处于临界状态,分别指出它们的优势因素和制约因子所在,为浙江省生态城市建设提供科学的决策依据。At present, ecosystem health has been regarded as a focal point and study frontier of applied ecology, which also has also been used more and more in urban ecological studies. This paper taking ecosystem health as its theoretic base, according the uncertainty of indicator information, put forward assessing and analyzing the questions of urban ecosystem health by unascertained measure model. Since urban ecosystem is a compound system, an urban ecosystem health assessment indicator system which consists of three subsystems economic-natural-social was set up. Taking nine cities in Zhejiang province as a case, assess their ecosystem healthy state. The results indicated Hangzhou, Ningbo and Shaoxing were on healthy state, while the other six cities were on critical state. Finally,this paper analyzed these cities＇s advanlages and limiting factors, and made suggestions for the city construction of Zhejiang province.
