珠三角城市群生态足迹分析

Analysis on Ecological Footprint of the Urban Agglomeration in Pearl River Delta

[目的]计算和分析2009年珠三角城市群生态足迹。[方法]以珠三角9个市为研究区,运用生态足迹计算模型对2009年珠三角市生态足迹和生态安全进行计算,定量分析珠三角区域生态环境现状和可持续发展状况。[结果]珠三角城市群除了建筑用地和林地稍显生态盈余外,其他4种土地类型均处于生态赤字状态,特别是可耕地和化石燃料用地,存在明显的生态赤字。[结论]珠三角生物资源消费水平和能源消费水平较高,应采取多种措施减少生态赤字,以使得发展方式向更加可持续性的方向转变。

[Objective] The research aimed to calculate and analyze ecological footprint of the urban agglomeration in Pearl River Delta in 2009.[Method] 9 cities in Pearl River Delta as research zone,by using calculation model of the ecological footprint,ecological footprint and security of the urban agglomeration in Pearl River Delta were calculated.Current situation and sustainable development condition of the ecological environment in Pearl River Delta were quantitatively analyzed.[Result] Except construction land and forest land,other 4 kinds of lands were all in ecological deficit statuses in Pearl River Delta.Especially arable land and fossil fuel land had obvious ecological deficit.[Conclusion] Biological resource consumption level and energy consumption level in Pearl River Delta were higher.We ought to take a variety of measures to reduce ecological deficit to make development manner turn toward sustainable direction.
