摘要
基于可持续发展观点,运用生态足迹分析法并结合GIS技术对甘肃省定西市2000年,2002年和2004年的土地可持续利用度进行了实证研究。结果表明:彰县在这3年中生态足迹一直小于生态承载力,土地处于绝对可持续利用范围内;其余6县区一直处于生态赤字状态,但从总体上看定西市处于土地可持续利用增强态势。
Based on the sustainable development opinion, we introduce the Ecological Footprint Analyses （EFA） and Geographic Information System （GIS） to analyze the degree of land sustainable use of Dingxi in 2000, 2002, 2004. The results show that the ecological footprint of Zhang Xian is always smaller than its ecological capacity, which means the degree of land use is absolutely sustainable. But the other counties are to be in the state of ecological deficit. Land sustainable use gradually enhance in Dingxi as a whole.
