【摘要】 通过构建交通足迹分解模型,对近年来沈阳市交通生态足迹进行分析.结果表明:沈阳市1995~2004年交通生态足迹总体呈逐年上升态势,但不同阶段各因素对足迹增长的贡献和影响不同.出行量变化始终表现为足迹的增量效应(其中小轿车是对交通足迹增长贡献最大的交通工具),但总体增幅逐渐趋缓.足迹强度和结构效应在该段时期表现为一定的增减波动,体现了由于经济发展和政策变动带来的环境压力冲击和影响差异.根据研究结果并结合该市未来交通可持续发展的形势,对沈阳交通环境减压提出了一些政策建议.更多还原

【Abstract】 Based on a decomposition model developed for the ecological footprint of traffic,the ecological footprints of traffic in Shenyang from 1995 to 2004 were analyzed.The results showed that,generally,the number of footprints increased year by year,while the different influencing factors on them played different roles in making contributions to the footprint growth in different periods.The change in traffic volume always embodied the increment effect on ecological footprint, in which cars made the greatest contribution to the traffic footprint,but,as a whole,the magnitude of increment tended to be stable and slow.In the period from 1995 to 2004,the effect of the change in ecological footprint intensity/structure showed fluctuation to a certain degree to reflect the difference in the impact due to environmental pressure caused by the economic development and policy alteration.In view of the research results in combination with the sustainable trend of urban traffic development,some suggestions are put forward as the policies to reduce the environmental pressure acting on Shenyang’s traffic.更多还原
