| 摘 要： | 用生态足迹的理论与方法,对陕西省关中地区2001—2008年的生态足迹和生态承载力进行了计算,并运用灰色预测模型对关中地区2010—2015的生态足迹做出预测。结果表明:当地人均生态足迹呈现上升趋势,由0.650 7 ha2.人-1上升到0.926 9 ha2.人-1,人均生态赤字不断增加,由0.145 5 ha2.人-1上升到0.492 4 ha2.人-1,生态赤字持续扩大,预测2015年人均生态赤字将达到0.780 9 ha2.人-1。区域生态处于不安全状况,生态可持续发展受到严重影响。 |

| Abstract: | This paper introduced the concept and calculation method of ecological footprint,and applied them to Guanzhong region for the time period from 2001 to 2008,and analyzed the ecological security and ecological footprint from 2009 to 2015 using the Gray Prediction Model.The results showed that:The per capita ecological footprint mounted continually,rising from 0.650 7 ha per capita to 0.926 9 ha per capita,ecological wane is growing continuously,increasing from 0.145 5 ha per capita to 0.492 4 ha2 per capita.T... |
