交通生态足迹理论研究进展

为了解生态足迹理论在城市交通中的应用现状，对国内外前人的相关研究进行了分析，结果表明:生态足迹在交通产业中有应用研究，并可以计算交通生态足迹，计算方法有两类，一是各类交通工具生态足迹计算，可用于横向比较，其中轨道交通和公共交通生态效率最高；二是从生命周期全过程计算某种交通工具的生态足迹，可以得知哪个阶段对该种交通工具的生态足迹贡献值最大.交通生态足迹方法可用于城市交通结构优化，以及私人小汽车发展政策研究，实现城市交通可持续发展，但在计算交通生态承载力方面，尚无模型；由于资料欠缺，具体到城市规模的应用研究偏少.因此，需要加强这些方面的研究，才能够切实为政府决策提供理论依据.

Research progress of traffic ecological footprint

In order to understand the present situation of urban traffic ecological footprint theory,previous related researches at home and abroad were provided and analyzed.Results show that there are some applied researches in urban traffic and the traffic ecological footprint can be calculated.There are two kinds of calculation methods: One is the ecological footprint of all kinds of vehicles,and the ecological efficiency of rail traffic and public transport was highest by compared with each other;the other is the ecological footprint of some forms of transport based on the whole life,which can be found out the stage that has maximum contribution to the ecological footprint.Traffic ecological footprint method can be used to optimize the structure of urban traffic and provide development policy research for private car to achieve the sustainable development of urban traffic.There is no mode in calculating of ecological carrying capacity of traffic and fewer researches in city scale lacking of datum.Researches must be made in these areas to provide theoretical basis for government decision effectively.
