| 摘 要： | 通过完全分解模型,把生态足迹分解为经济规模、产业结构和足迹强度3种因素的变化效应,为定量研究影响环境压力的因素提供一种思路。对武汉市1995～2020年生态足迹的动态变化的研究表明:生态足迹变化是由各因素共同作用的结果,而在不同时期各因素对足迹变化所发挥的效应不同;总的看,经济规模的增长助长总足迹的增加,而足迹强度的降低对总足迹的扩张起到了一定的遏制作用,产业结构的变动先是对生态足迹的增长起遏制作用,随后对生态足迹的增长起促进作用。

| Abstract: | With complete decomposition model,ecological footprint was decomposed to three different changing effects,namely GDP,structure of industry economy and ecological footprint identity of industries,so a new methord was build to explore some main factors impacting on environmental pressure.Ecological footprint's dynamic variation of Wuhan during the period from 1995 to 2020was studied,and the results showed that varied factors impacted together on variation of ecological footprint and these factors exerted diff... |
