运用改进型能值生态足迹模型计算出长沙市各区县2006~2015年的人均生态承载力与人均生态足迹,并运用GM(1,1)模型得出2016~2025年的预测值.发现长沙市各区县的人均生态赤字呈现三种变化趋势:一是生态赤字逐渐加大,二是生态赤字处于相对稳定状态,三是逐渐加大后出现拐点,转变为逐渐减少甚至出现生态盈余.根据人均生态赤字的这三种变化特征将长沙市划分为生态红区、生态黄区和生态蓝区,对比分析其生态安全状况,为经济发展规划提供参考.

This study calculates the per capita ecological carrying capacity and ecological footprint for the years between2006and2015for all districts and counties in the city of Changsha.The study used a modified model of emergetic ecological footprint and predicted the results from the years between2016and2025using a GM(1,1)model.The results show that the per capita ecological deficit presents three change trends:one increased gradually,one was in a relatively stable state,and the third gradually increased to the inflection point,then reduced and even appeared as ecological surplus.According to these ...
