摘要: 生态足迹是一种度量可持续发展程度的方法,能定量判断一个区域生态环境是否处于可持续发展状况。基于生态足迹方法对2003年广西生态环境的可持续发展状况进行了评估。结果表明,广西2003年生态足迹为1.1378 hm2,可利用的人均生态承载力为0.5753 hm2,对资源的需求已超过其供给能力,人均生态赤字达到0.5625 hm2,生态环境已经处于不可持续发展状态,必须采取相应措施促使生态环境发展向良性和可持续方向转化。

Abstract: Ecological footprint is a method for measuring the degree of sustainable development, which can be used to judge in quantity whether a regional ecological environment is under sustainable development status. Based on this method, the sustainable development status of ecological environment in Guangxi Province in 2003 was estimated, and the results showed that the per capita ecological footprint of Guangxi in 2003 was 1.1378 hm2, and the per capita ecological capacity was 0.5753 hm2. The resources demand was already exceeded their load, and the per capita ecological deficit was up to 0.5625 hm2, suggesting that the ecological environment of Guangxi Province was in an unsustainable state, and corresponding countermeasures should be taken.
