摘要
以黑龙江省2005年统计数据为基础,运用传统以及基于能值分析理论的生态足迹模型,对黑龙江省2005年可持续发展状况进行定量分析。结果表明,改进生态足迹模型的人均生态足迹为4.9995 hm2,人均生态承载力为1.4168 hm2,人均生态赤字为3.5827 hm2;传统生态足迹模型的人均生态足迹为2.4859 hm2,人均生态承载力为1.8629 hm2,人均生态赤字为0.6256 hm2。两种生态足迹模型的计算结果基本一致,表明该地区生态足迹超过了生态承载力,区域经济社会发展处于一种不可持续的发展状态。
Based on the statistical data of Heilongjiang Province, the traditional and the modified ecological footprint model based on energy analysis were used to quantitatively analyze the sustainable development status in 2005 of Heilongjiang Province. The results showed that the per capita modified ecological footprint was 4.9995 hm^2, ecological capacity was 1.4168 hm^2, and ecological deficit was 3.5827 hm^2; the per capita traditional ecological footprint was 2.4859 hm^2, ecological capacity was 1.8629 hm^2, and ecological deficit was 0.6256 hm^2. The results of two different ecological footprint models were consistent, which indicated that the ecological footprint of Heilongjiang Province was beyond the available ecological capacity, and its social and economic development was not sustainable.
