摘要
应用William Rees等提出的生态足迹分析法对陕西省2003年生态足迹进行了定量计算和分析。结果表明,2003年陕西省人均生态足迹为1.9298 hm2,可供给的人均生态承载力面积仅为0.8040 hm2,陕西省生态足迹是生态承载力面积的2.40倍,表明陕西省生态系统承受着较大的压力。同时对应用生态足迹分析法需要注意和完善的方面进行探讨。
The ecological footprints analysis initiated by William E. Rees, Canadian ecological economist and Wackernagel Mathis, the former＇ s postgraduate, is a system of index for measuring sustainable development. Based upon the introduction of it＇s theory, system of index and computation, the consequence of analyze ing ecological footprints of Shaanxi Province in 2003 indicates that the ecological footprints of whole province in less than it＇s ecological capacity in numerical value. As a result, ecological deficit of Shaanxi Province in 2003 causes the province belong to the region of unsustainable development in locality-sustainable development it globe. Finally, the thesis briefly discusses the aspects need to be noticed and consummated.
