基于能值——生态足迹的安康市可持续发展评价
Assessment of Sustainable Development Based on Energy Theory and Ecological Footprint——A Case Study of Ankang
摘要
Abstract
Taking the municipal ecosystem of Ankang as object,by combining the energy value theory and the ecological footprint models together, the amounts of ecological carrying capacity and the demands of ecological footprints between 2004 to 2008 were calculated, and an assessment was conducted in the view of regional sustainable development. In the years of 2004 to 2008, the energy-based ecological footprints were 11. 90 hm2,ll. 83 hm2, 11. 59 hm2,11. 57 hm2 ,and 11. 40 hm2 per capita,respectively. The energy-based ecological carrying capacities were 4. 28 hm2,4. 69 hm2,4. 00 hm2,4. 44 hm2 ,and 4. 89 hm2 per capita, respectively. The sustainability energy indices were 0. 74,0. 72. 0. 74,0. 72,and 0. 70,respectively. The energy-based ecological footprint was beyond the carrying capacity,and turned out ecological deficit,resulting in poor ecological safety,which meant the consumption of resources was highly beyond the supply of the resources.关键词
