摘 要:运用生态足迹理论和方法对广西柳江县2006年生态足迹进行了实证计算和分析,从供需平衡状况、供需结构和资源利用效率三方面定量分析了柳江县生态系统可持续发展的状况。结果表明:1)2006年柳江县人均生态赤字人0.095hm2/人,人类活动对区域生态经济系统的影响已超出了其生态承载力的阈值,区域生态经济系统的结构和功能亟需调整;2)柳江县人均生态足迹和人均生态承载力具有明显的不对称性,其生态足迹以耕地为主,生态承载力以耕地和化石燃料用地为主,可用于人类消费的生态承载力结构较为单一;3)万元GDP生态足迹的区域对比表明,当前柳江县资源利用效率还较高。The ecological footprint (EF) of Liujiang County of Guangxi Province, China in 2006 was evaluated by using ecological footprint theory and method. Based on it, balance of supply and demand, the structure of supply and demand, and the efficiency of biological resources usage are analyzed respectively to reveal the sustainability of ecosystem of Liujiang County. The results show that: 1) The per capita EF deficit of Liujiang County in 2006 is 0.095 hm^2 , which means the effect of human activities on the eco-economic system of this region has already exceeded the benchmark of ecological carrying capacity. The structure and functions of regional eco-economic system must be adjusted. 2) The structure of EF and EC of Liujiang County is obviously dissymmetry, which the main EF is arable land and the main EC is fossil energy land, and shows the EC for human consumption is relatively single. 3) The regional comparison of EF with ten thousand yuan GDP shows that the efficiency of biological resources utilization of Liujiang County is rather high.
