摘　　要：为了研究城市轨道交通项目因碳减排带来的环境效益,融合建设与运营数据,构建了城市轨道交通项目的碳回收期测算模型。以长沙市5条轨道交通线路为研究对象,在合理预测未来客运量的基础上,定量分析了这5条线路在2014—2050年间建设、运营的碳足迹变化。研究发现:城市轨道交通项目具有显著的碳减排效益,5条线路均能在2050年前完全回收建设阶段的碳排放,之后通过碳排放交易还将产生正效益。同时,还发现轨道交通项目的碳减排效益大小受客运量饱和情况的直接影响。In order to study the environmental benefits of urban rail transit projects brought by carbon emission reduction,construction and operation data were integrated to construct a carbon payback period calculation model for urban rail transit projects.Taking 5 rail transit lines in Changsha city as the research object,based on a reasonable forecast of future passenger traffic,the carbon footprint changes of these 5 lines during construction and operation from 2014 to 2050 were quantitatively analyzed.It is found that the urban rail transit project has significant carbon emission reduction benefits.All five lines can fully recover the carbon emissions of the construction stage by 2050,and afterwards,carbon emissions trading will also generate positive benefits.At the same time,it maintains that the carbon emission reduction benefits of rail transit projects are directly affected by the saturation of passenger traffic.

关 键 词：城市轨道交通项目 碳回收期 碳足迹 碳减排效益
