| 摘 要： | 以重庆市2005年统计数据为基础,计算生态足迹和生态承载量,计算结果显示该地区人均生态足迹为1.547841 hm2,人均生态承载力为0.368 038 hm2,人均生态赤字为1.179803 hm2。与全国平均水平相比,人均生态足迹高0.427841 hm2,人均生态承载力低0.431962 hm2,生态赤字是全国生态赤字的2.95倍。表明重庆市生态经济系统存在严重的生态赤字,必须采取相应措施,才能减少生态系统的压力。

| Abstract: | Based on the statistical data of Chongqing in 2005,the ecological footprint and available ecological capacity of the city were calculated.The per capita ecological footprint was 1.547 841 hm2,per capita ecological capacity was 0.368 038 hm2,and ecological deficit was 1.179 803 hm2.Compared with the average national level,Chongqing's per capita ecological footprint was 0.427 841 hm2 higher and its per capita ecological capacity was 0.431 962 hm2 lower.It's ecological deficit was 2.95 times than the average national level.These figures indicate that there is a severe ecological deficit in the system of ecological economy of Chongqing.We must take suitable measures to lessen the pressure of the ecological system. |
