摘要
应用William Rees等提出的生态足迹分析法对大连市2005年生态足迹进行了定量计算和分析。结果表明,2005年大连市人均生态足迹为3.2018 hm2,可供给的人均生态承载力面积仅为0.849 hm2,大连市生态足迹是生态承载力面积的3.78倍,表明大连市生态系统承受着较大的压力,大连市可持续发展不乐观。
The ecological footprint which was initially presented by William Rees is applied to analyze quantitatively the ecological footprint of Dalian in 2005 with the results indicating that, in 2005, the average footprint is 3. 2018 hm^2 per person, the average load area is 0. 849 hm^2 per person. The 3.78 times of ecological footprint to ecological load imply a big pressure over the ecological system, which is an adverse factor for the sustainable development of Dalian city.
