摘要
本文对陕西省2001—2010年的生态足迹及生态承载力进行了动态量化计算,并引用生态压力指数、万元GDP生态足迹、生态足迹多样性指数和生态系统发展能力等指标对计算结果进行了进一步分析。结果表明:陕西省近10年发展一直处于生态赤字状态,人均生态足迹年均增长率达到7.856%,生态赤字年均增长率高达15.772%;造成这种现象的主要原因是经济发展对建筑用地和化石能源用地的过度耗用;近10年陕西省的生态压力指数均大于1,且呈现增强的趋势,但万元GDP生态足迹则出现明显下降趋势,说明对资源利用效率显著提高;生态系统发展能力也有很大提升,但是2010年已超出其发展潜力,经济社会与自然资源的发展持续性出现矛盾,生态经济发展处于相对不可持续发展状态。
This paper calculates ecological footprint and ecological capacity during 2001--2010 in Shanxi Province. The annual growth rate averaged of per ecological footprint has reached 7. 8559%, and the deficit of per ecological capacity has also been up to 15. 772%, which indicates that the development of Shanxi Province is in an unsustainable state in the last ten years. The main reason for this phenomenon is excessive consumption of building land and fossil energy in economic development. Ecological pressure index presenting enhancement trend altogether has passed 1, while per ten thousand Yuan GDP shows a significant decline tendency, which indicates that the energy efficiency has a remarkable improvement. There is a significant enhancement in the capacity of ecosys- tem development. But ecosystem development capacity has exceeded its development potential in 2010, which shows that the devel- opment of an ecological economy is in a relatively unsustainable state.
