摘要
为加快实现我国高速铁路碳达峰,并推动高速铁路行业深度减排,首先,采用生命周期评价方法明确高速铁路运营阶段的碳排放来源,在此基础上构建碳排放定量测算模型;然后,根据相关碳排放指标建立高速铁路运营阶段低碳化水平评价指标体系,利用基于层次分析法和变异系数法的灰色关联分析构建综合评价模型,对2013—2016年京沪高铁运营阶段进行碳排放测算和低碳化水平评价;最后,针对高铁运营阶段各系统的碳排放特征提出节能减排的措施建议。研究结果表明,在运营阶段京沪高速铁路牵引系统碳排放占比为89.2%,车站系统占比为6.4%,养护系统占比为4.4%。其中,牵引系统和车站系统的年度总碳排放水平均在逐年提高;养护系统中钢轨、水泥的生产及施工环节碳排放占比最大,分别为36%和25%。因此,需重点优化牵引供电和车站运营环节的电力生产结构,开发高碳排建筑材料生产和施工环节的节能降碳技术,以获得最大化的节能减排效益。此外,综合评价结果表明,京沪高铁运营阶段的低碳化水平正逐年提高。
To accelerate the peaking of carbon emissions in the high-speed railway sector in China and promote deep carbon emission reduction in the industry,firstly,the LCA(Life Cycle Assessment)was used to identify the sources of carbon emissions during the operation phase,and then a quantitative calculation model for carbon emissions was constructed.Secondly,based on relevant carbon emission indicators,an evaluation index system for the the low-carbon level during the operation phase of high-speed railway was established.The comprehensive assessment of this index system was conducted using a Grey Relational Analysis model,combining AHP(Analytic Hierarchy Process)and Coefficient of Variation.Subsequently,carbon emission calculation and a low-carbon level assessment were performed for the Beijing-Shanghai High-speed Railway during the operation phase from 2013 to 2016.The research findings indicated that,during the operational phase,the carbon emissions from the traction system of the Beijing-Shanghai High-speed Railway constituted 89.2%,the station system contributed 6.4%,and the maintenance system accounted for 4.4%.Notably,the annual total carbon emissions from the traction and station systems increased year by year.Within the maintenance system,carbon emissions from the production and construction of rails and cement accounted for the targest portions,which were 36%and 25%,respectively.Therefore,there was a need to prioritize the optimization of the power production structure in the traction and station operation phases,as well as the development of energy-saving and carbon-reducing technologies in the production and construction processes of high-carbon building materials,to attain maximum energy-saving and emission reduction benefits.Additionally,the evaluation results indicated that the low-carbon level of the Beijing-Shanghai Highspeed Railway was increasing year by year during its operation phase.
