基于传统生态足迹法与能值生态足迹法的岳阳市可持续发展

Sustainable Development of Yueyang City Based on Methods of Conventional Ecological Footprint and Energy Ecological Footprint

为全面了解岳阳市的生态环境状况和可持续发展能力,运用传统生态足迹法和能值生态足迹法对岳阳市2007年的可持续发展状况进行比较分析,结果表明:按能值生态足迹法计算,2007年岳阳市人均生态足迹为10.03753 hm2,人均生态承载力为1.49204 hm2,人均生态赤字8.54549 hm2;按传统生态足迹法计算,2007年岳阳人均生态足迹为3.838203 hm2,人均生态承载力为0.469098 hm2,人均生态赤字3.369105 hm2。两种方法计算的生态足迹都超过了生态承载力,表明岳阳市社会经济发展处于不可持续状况。

The sustainable development status of Yueyang city was calculated by conventional ecological footprint and energy ecological footprint methods to overall understand the ecological environmental situation and sustainable development ability of Yueyang city.The results showed that the per capita ecological footprint,per capita biological bearing capacity and per capita ecological deficit calculated by the conventional ecological footprint method and energy ecological footprint method were 10.03753hm^2,1.49204hm^2 and 8.54549hm^2,and 3.838203hm^2,0.469098hm^2 and 3.369105hm^2 respectively in 2007.The ecological footprint calculated by two methods exceeds the biological bearing capacity,which indicates that the social and economic development is in an unsustainable status.
