基于生态足迹的县域可持续发展状况评价——以广西都安瑶族自治县为例

An Analysis of County's Sustainable Development Situation Based on Ecological Footprint Model —take Duan county as an example

生态足迹模型是一种定量研究可持续发展的新方法.该方法能够定量衡量人类对自然利用程度.文章运用生态足迹法计算和分析了都安县1997、2001和2002年的生态足迹、生态承载力以及生态足迹多样性、生态经济系统发展能力和万元GDP的生态足迹.结果显示,近5年来都安县人均生态足迹大大高于人均生态承载,出现了生态赤字.整个县域呈现出生态足迹多样性指数较低、生态经济系统发展能力不强和万元GDP的生态足迹过高的特点,这表明当前都安县的自然资源利用率很低,县域的发展处于一种非可持续状态.提出了减少生态赤字,实现县域可持续发展的途径.

Ecological footprint is a new means for the quantitative research of sustainable development. The way can quantitatively measure the influence of human beings on nature. This article calculated and analysed Duan county's ecological footprint、ecological capacity、ecological footprint diversity、development capability and ecological footprint of one million GDP between 1997—2002 by the application of ecological footprint model, the result showed that Duan county's ecological footprint is far higher than its ecological capacity,thus ecological deficit appeared. Index of ecological footprint diversity is low,the development capability of ecological economy system is not strong, but index of ecological footprint of one million GDP is too high,which indicates that the development situation of Duan county is not sustainable currently. Finally,some countermeasure has been put forth for the decrease of ecological deficit and sustainable development in Duan county.
