摘要
通过研究1992～2005年南京市生态足迹的变化,文章认为南京市人均生态赤字与人口、GDP表现出明显的相关性。根据人均生态足迹的研究结果,化石燃料用地占主导地位。在人均生态承载力上,南京市人均生态承载力中耕地占到整个生态供给的近90%。从2002年开始,南京市赤字已超过12.99×104km2,超过南京市自身国土面积的20倍,处于不可持续状态。因此,南京市需尽快进行社会经济结构调整,严格控制人口增长,对耕地实行严格的保护,提高能源利用效率和降低能源消耗等,从而减少生态赤字,促进社会经济可持续发展。
The change of ecological footprint from 1992-2005 in Nanjing was studied in this paper and the results Showed that per capita ecological deficit has a strong relativity with population and GDP. According to the results of study on per capita ecological footprint, land for fossil energy is dominant. In addition, plantation occupies nearly 90% of total ecological supply in per capita ecological capacity. From 2002, ecological deficit in Nanjing exceeds 2.99×10^4km^2, which is 20 times more than territory of Nanjing and is unsustainable. Therefore, the paper suggests that Nanjing should adjusts its social and economic structure as soon as possible, controls population increase firmly, protects arable land strictly, increases energy efficiency and decrease energy consumption in order to reduce ecological deficit and advance sustainable development Of society and economy.
