摘要
利用生态足迹分析方法对天津市1989—2008年的生态足迹进行了计算和分析。计算结果表明:天津市人均生态足迹由1989年的1.64 hm2上升到2008年的1.65 hm2;同期的人均生态承载力则由0.27 hm2逐年上升到0.32 hm2;人均生态赤字由1.36 hm2降到1.32 hm2。虽然天津市人口对自然资源的利用呈下降趋势、生态足迹与生态承载力之间的矛盾有所减缓,但生态足迹目前仍然超出了自然生态系统的生态承载力范围,现有的发展模式是不可持续的,生态环境处于较不安全的状态。
Ecological footprint analytical methods used in Tianjin in 1989,the ecological footprint of the calculation and analysis,calculations show that the ecological footprint ：Tianjin per capita in 1989 1.64 hm2 up to 2008 1.65 hm2;the per capita GNP by the ecological bearing capacity 0.27 hm2 has risen to 0.32 hm2;per capita ecological deficit by 1.36 hm2 to 1.32 hm2.AlthoughTianjin population on the use of natural resources,has declined,the ecological footprint and ecology bearing capacity the contradiction between had----somewhat,ecological footprint is still beyond the natural system of the ecological bearing capacity,the existing mode of development is unsustainable and ecological environment is less safe condition.
