【摘要】 作为能源消耗和碳排放的重要行业，城市轨道交通在运营阶段能耗占比高，碳减排潜力大。鉴于此，通过广泛的调查研究，并借鉴国内外发展模式，归纳了城市轨道交通“源-车-储-网”多维度融合发展策略，建立了碳排放测算模型。通过情景分析法对基准情景、清洁能源占比、各系统的节能效率等多种情景下的碳排放进行了测算分析，研究结果表明：在基准情景下，有望实现2030碳达峰目标，清洁能源占比达到75%时，有望实现2060碳中和目标；对城市轨道交通碳排放的影响按显著程度排序依次是清洁能源、环控系统、牵引系统和再生制动系统。该项研究可为制定城市轨道交通引领政策提供理论依据，助力城市轨道交通早日实现双碳战略目标，具有重要的理论意义和社会价值。更多还原

【Abstract】 Being a significant industry in energy consumption and carbon emissions, urban rail transportation accounts for a substantial portion during the operational phase, and presents significant potential for reducing carbon emissions. In light of this, extensive research and insights from both home and abroad development models were leveraged to summarize a multi-dimensional integration strategy of energy, train, storage, and network was proposed for urban railway system. And a carbon emission calculation model was established. By employing scenariobased analysis, carbon emissions were calculated and analyzed under multiple scenarios of baseline scenario, the proportion of clean energy, and the energy-saving efficiency. The research indicate that carbon peaking will be achieved by 2030 under the baseline scenario. Carbon neutrality will be achievable with a clean energy proportion of75% by 2060; In order of significance, the factors impacting carbon emissions of urban rail transportation are clean energy, environmental control systems, traction power systems, and regenerative braking systems. This study help to provide theoretical basis for urban rail transportation policies, facilitate the realization of the dual carbon objectives, and offer great theoretical and social value.更多还原
