文中着重讨论了城市生态系统健康的评价方法及其应用,采用熵权法赋予指标权重,应用模糊数学方法建立评价模型,以重庆市为例进行城市生态系统健康评价.首先,以北京,天津,上海作为参照城市,进行横向评价,评价结果表明4个城市均处于亚健康状态;其次,对重庆市2001～2004年生态系统健康状况进行纵向评价,评价结果表明,重庆市生态系统健康状况正从亚健康状态向健康状态发展;最后,对重庆市都市圈所包括的9个区进行现状评价,运用GIS技术进行等级划分,得出重庆都市圈生态系统健康状态的排序如下:渝北区＞南岸区＞渝中区＞巴南区＞九龙坡区＞江北区＞沙坪坝区＞大渡口区＞北碚区.

An evaluation method of urban ecosystem health and its application were emphatically discussed, in which the entropyweighing method was employed to give indexes weight, and the fuzzy mathematics method is utilized to establish the evaluation model. Subsequently, the situation of urban ecosystem health in Chongqing was selected as a study case, and the ecosystem health towards Chongqing, Beijing, Tianjin and Shanghai was crosswise evaluated, finding that the above-mentioned four cities were all situated in sub-healthy state. Also, a longitudinal evaluation of the ecosystem health of Chongqing from 2001 to 2004 was carried out, showing that the condition of urban ecosystem health was developing from sub-healthy state to healthy state. Finally, the present conditions of ecosystem health state of nine districts in Chongqing Metropolis were investigated, and the rank division of ecosystem health was presented in virtue of GIS-based technology. Thus, an order of the state of ecosystem health was illustrated as: Yubei ＞ Nan'an ＞ Yuzhong ＞ Banan ＞ Jiulongpo ＞ Jiangbei ＞ Shapingba ＞ Dadukou ＞ Beibei.
