摘要
重庆市是中国最大的内陆山区城市,人类活动强烈,生态系统脆弱;又位于长江三峡水库的库尾,生态地位十分重要,开展重庆都市圈生态系统健康评价研究具有特殊的意义。在详细阐述重庆都市圈生态系统健康评价指标建立和评价标准确定的基础上,通过熵权法赋予指标权重,运用灰色关联法对重庆都市圈生态系统健康状态进行评价研究,得出重庆都市圈生态系统健康状态排序:渝北区(南岸区(江北区(沙坪坝区(九龙坡区(大渡口区(北碚区(巴南区(渝中区。
Chongqing is one of the largest inland mountainous cities in China, where the activities of human beings are intense and the ecosystem is fragile. It lies in tail area of Tree-Gorges reservoir, the important ecological status makes it necessary to investigate the ecosystem health of Chongqing metropolis. On the base of demonstrating the details of establishing the evaluation indexes and confirming the evaluation standards, this paper endows weighing to indexes by entropy-weighing method and evaluates the state of ecosystem health in Chongqing metropolis by grayscale relative method , finally gives an order of the state of ecosystem health as followed ： Yubei district 〉 Nan＇an district 〉 Jiangbei district 〉 Shapingba district 〉 Jiulongpo district 〉 Dadukou district 〉 Beibei district 〉 Banan district 〉 Yuzhong district.
