长株潭城市群土地生态承载力评价研究

Evaluation of Ecological Carrying Capacity in Changsha-Zhuzhou-Xiangtan Metropolis

该文利用生态足迹的原理和模型计算了长株潭城市群2006年的生态足迹和土地生态承载力,结果发现,2006年长株潭城市群人均生态足迹大大超过其土地生态承载力,出现了生态赤字。从横向比较看,长株潭城市群的人均生态足迹超出全球和中国平均水平,由此可见,长株潭城市群生态发展处于不可持续状态。为适应建设"长株潭城市群两型社会"的需要,必须建立起资源节约型、环境友好型、消费生态型的新型社会经济发展模式。

This paper calculated the ecological footprints and the land carrying capacity of Changsha-Zhuzhou-Xiangtan metropolis in 2006 by adopting the ecological footprint principle and model. The results showed that the ecological footprint per capita in Changsha-Zhuzhou-Xiangtan metropolis surpassed the land carrying capacity per capita. Compared with other countries and regions, the eeologieal footprint of Changsha- Zhuzhou-Xiangtan metropolis was higher than the global and the average level of China. The ecological development in Changsha-Zhuzhou- Xiangtan metropolis was in an unsustainable condition. It was urgent to establish new models of social and economical development which is resources-saving, environment-friendly and consumption-ecological by practicing thrift in resources using and consumption.
