广西北部湾地区生态足迹动态分析

Dynamic research of ecological footprint in North Gulf of Guangxi Province

生态足迹方法为定量计算地区可持续性发展提供了一种简单易行的方法。论文将在传统生态足迹方法的基础上结合目前国外最新生态足迹动态分析方法对广西北部湾地区从1998年到2005年的生态足迹进行了计算。结果表明:结合万元GDP占用生态足迹、生态足迹多样性指数和经济系统发展能力指数等指标的生态足迹动态分析方法,加强了传统生态足迹方法对地区可持续发展状况的反应。1998～2005年期间,广西北部湾地区,土地生产效率不断提高,经济发展能力在逐步增强,但是人均生态足迹呈逐年增加趋势,出现生态赤字,处于不可持续发展状态,仅林地资源与建筑用地资源还有少量人均盈余。

Ecological Footprint Method （EFM） is an effective way to quantitatively analyze the sustainability of certain areas. Combining the traditional EFM with the newest dynamic analysis method, this paper calculates the ecological footprint of the North Gulf in Guangxi Province. Our study indicates that the dynamic EFM, composed of ecological footprint diversity index and development capacity index of economic system, provides more remarkable results than the traditional EFM in sustainability analysis. During the period between 1998 and 2005, the land productivity has been improving continuously, and the ability of economy development has been strengthening gradually. However, per-capita ecological footprint increases year by year, and the ecological footprint deficit appears. In conclusion, the development of the North Gulf of Guangxi province is not sustainable, with only woodland and architectural land remains a little surplus.
