摘要
为了给西安市的可持续发展提供可行的理论依据,在介绍生态足迹的概念和计算方法的基础上,以2005年西安市统计年鉴的数据为依据,对西安市的生态足迹进行了实证研究。结果表明,西安市人均生态足迹为1.07 hm2,可利用的人均生态承载力为0.23 hm2,人均生态赤字为0.84 hm2,较大的生态赤字反映出目前西安市对生物生产土地面积的需求量已经严重超过区域生态系统的承载能力,区域生态系统处于过度开发利用压力之下,其发展模式处于一种不可持续的状态,最后提出了减缓西安市生态赤字的对策。
Based on the introduction to the concept and calculation method of ecological foot-print, the ecological footprints of Xi＇an in 2005 were calculated and analyzed according to the data of the statistical yearbook. The results showed that the ecological footprint per capita was 1.07 hm^2 ,the ecological carrying capacity per capita was 0.23 hm^2 and the ecological deficit per capita was 0.84 hm^2. The high ecological deficit showed that the human load had already gone beyond the regional bio-capacity and the regional natural ecosystem was under great pressure of human activities. The development mode of Xi＇an was in an unsustainable status. Finally a series of measures to reduce ecological deficit based on the analysis of result were brought forward as well.
