北京市人口生态足迹变动定量分析

Quantitative analysis to the change of ecological footprint of Beijing

利用生态足迹方法对北京市的可持续发展状况进行了分析,并利用IPAT模型对北京市的生态足迹影响因素进行了定量测量。结果表明,北京市自1980年以来生态足迹总量持续迅速增加,人均生态足迹量也总体呈上升趋势,生态环境状况不断恶化。通过对北京市生态足迹影响因素的定量分析,发现经济因素是最重要的影响因素,之后依次是技术因素和人口总量因素,而人口城镇化率在过去30年间对北京市的生态足迹并无显著影响。

This essay studies the sustainable develop- ment situation of Beijing with the ecological footprint method. By using the IPAT model, this essay examines the influencing fac- tors of the ecological footprint quantitatively in Beijing. It reveals that the total ecological footprint of Beijing has kept rising since 1980, and the per capital ecological footprint is also on the rise overall. They all indicate that the ecological environment of Bei- jing is worsening. The results show that economic factor has the most important influence on the change of the ecological foot- print, followed by technology factor and the population size fac- tor. There is little correlation between urbanization and ecologi- cal footprint of Beijing during the past 30 years.
