生态足迹的动态测度与分析——陕西省可持续发展研究

Dymamic measurement and analysis of ecological footprint——Research in sustainable development of Shaanxi province

确定人类的活动是否处于生态系统的承载能力范围之内,是定量评估区域可持续发展研究的关键。生态足迹模型是一种测算人类对自然利用程度的新的综合指标,能定量判断一个区域的发展是否处于生态承载力的范围内。本文基于生态足迹理论和计算方法,对陕西省1999—2006年生态足迹和生态承载力进行了计算与分析。结果表明,陕西省的生态足迹一直处于生态赤字状态,其发展模式是不可持续的。

It is the key field of studying on region sustainable development to judge whether the existence condition of the mankind stays within the global carrying capacity or not. The ecological footprint（EF） model is a new aggregative indicator which proposed to assess the utilization degree of the nature. This method can provide new idea to assess the regional development. According to ecology footprint theory and the calculation method, ecology footprint and carrying capacity of Shaanxi province from 1999 to 2006 were calculated and analyzed. The results indicated that Shaanxi＇ s ecological footprint is on ecological deficit condition continuously, and the development mode is unsustainable.
