摘　　要：轨道交通作为城市公共交通的重要组成部分,为低碳交通的绿色发展及移动源的温室气体减量排放做出了突出贡献。定量分析轨道交通对城市交通的碳减排贡献,将为低碳城市建设及绿色管理提供理论基础。基于此,本研究以上海市城市轨道交通为例,以轨道交通运营期的线路及站点能耗所产生的碳排放为核算边界,建立基于“自下而上”的碳减排核算方法。估算得到上海市轨道交通2023年碳减排量为4355304.39 tCO_(2)。通过分析运营期内的客流以及能耗情况对轨道交通碳减排量的影响,并对比典型区域和线路的碳减排潜力,结果发现轨道交通仍具有巨大的降碳发展空间。结合情景假设,本研究对轨道交通未来的低碳发展前景作出预测,研究证实在能源结构调整下,相较于其他交通模式,轨道交通仍具有明显的碳减排优势。本研究的结果将为低碳交通的绿色发展,充分挖掘轨道交通碳减排潜力提供科学依据。As an important part of urban public transportation,rail transit has made outstanding contributions to the green development of low-carbon transportation and the reduction of greenhouse gas emissions from mobile sources.Quantitative analysis of the carbon emission reduction contribution of rail transit to urban transportation will provide a theoretical basis for the construction of low-carbon cities and green management.Based on this,this study took Shanghai urban rail transit as an example,taking the carbon emissions generated by the energy consumption of lines and stations during the operation period of rail transit as the accounting boundary,to establish a"bottom-up"carbon emission reduction accounting method.The annual carbon emission reduction of Shanghai rail transit in 2023 was estimated to be 4355304.39 t CO_(2).Through analyzing the impacts of passenger flow and energy consumption on the carbon emission reduction of rail transit during the operation period,and comparing the carbon emission reduction potentials of typical regions and routes,the results showed that the rail transit still had a huge space for the development of carbon reduction.Combined with scenario assumptions,this study predicted the future low-carbon development prospects of rail transit.The study confirmed that under the adjustment of energy structure,rail transit still had obvious carbon emission reduction advantages compared with other transportation modes.The results of this study would provide a scientific basis for the green development of low-carbon transportation and fully tap the carbon emission reduction potential of rail transit.
