| 摘 要： | 对陕西省2001年生态足迹进行计算与分析结果表明,陕西省2001年人均生态足迹为1.6888hm2,人均生态承载力为0.9276hm2,人均生态赤字为0.7612hm2,生态足迹是生态承载力的1.8倍。说明陕西省2001年生态系统承受着较大的压力,这种压力主要来源于耕地足迹,耕地生态赤字为0.4919hm2/人,占总生态赤字的64.62%。

| Abstract: | The ecological footprint is useful for measuring the impact of human's consumption on ecosystem.The ecological footprints of Shaanxi province in 2001 are calculated in this paper and the result is:the ecological footprint of Shaanxi province is 1.688 8 hm~2 per capita,the ecological carrying capacity of Shannxi province is 0.927 6 hm~2 per capital,the ecological deficit of it is 0.761 2 hm~2 per capita,the ecological footprint of Shaanxi province is 1.8 times of its ecological carrying capacity.The fact states clearly that the ecosystem endures more pressure,the pressure is mainly from the ecological footprint of farmland,the ecological deficit of farmland is 0.491 9 hm~2 per capita,64.62 percent of the total ecological dificit. |
