基于生态足迹模型的陕西省生态承载力定量评估

近年来国内外影响较大的生态足迹分析模型,通过对区域人口对自然利用程度的测度,确定区域的发展是否处于生态承载力范围之内。利用生态足迹理论,选择1999、2001及2003年为代表年份,对陕西省人均生态足迹和人均生态承载力进行实证计算和分析,揭示陕西省可持续发展制约因子;分析不同生物生产性土地类型足迹的变化对陕西省生态环境的影响效应,为区域环境生态和社会经济的协调发展提供参考。

Calculation on Eco-capacity of Shanxi Province Based on Eco-footprint Model

The eco-footprint analysis(EFA) is a new model for sustainable development evaluation based on measuring quantitatively nature resources utilization,whether the development of region stays within the eco-carrying capacity or not is judged.Taking Shaanxi province as an example,the eco-footprints of this province in 1999,2001 and 2003 were calculated and analyzed with the relative literature,and the factors which restricted the sustainable development of Shaanxi province were put forward;At the same time, the effects caused by the changes of 6 kinds of eco-footprints were illuminated too on the environment of Shaanxi province,which put reference to the development and harmony of the region's economy and environment.
