摘要
生态足迹方法是研究区域可持续发展能力的一个重要方法,本文运用生态足迹模型对四大都市1997-2014年的人均生态足迹进行计算与比较研究。结果显示:1总体上,北京的人均生态足迹呈现下降趋势,2014年相比1997年减少了25.8%;上海的人均生态足迹变化较小;天津和重庆的人均生态足迹呈现上升趋势,2014年相比1997年分别增长了49.5%和71.8%。2在足迹构成中,四大都市的化石燃料用地足迹所占比重呈现不断上升趋势,成为影响人均生态足迹增长的决定性因素。为了控制生态足迹的增长,本文在结果分析的基础上,提出了相关政策建议。
Ecological footprint is an important way to study the capacity of sustainable development of the region. In this paper, the use of ecological footprint model for the four metropolitan 1997-2014 per capita ecological footprint is calculated and compared. The results showed that： Overall, Beijing＇s per capita ecological footprint shows a declining trend, which decreased by 25.8% compared to 1997; Shanghai＇s per capita ecological footprint experienced little change; Tianjin＇s and Chongqing＇s per capita ecological footprint showed a rising trend, compared to 1997 it increased by 49.5% and 71.8% respectively in 2014; 2ln the footprint components, the proportion ecological footprint of the four metropolitan of the fossil fuel land showed a rising trend, which is the decisive factor affecting the growth of per capita ecological tbotprint. In order to control the growth of ecological footprint, based on the analysis of the results, this paper puts forward the relevant policy recommendation.
