摘　　要：基于生命周期评价理论,以西安市航天中路机动车道建设阶段为研究对象,构建了碳排放清单,并采用碳排放因子计算法,对施工建造、材料生产和材料运输三个过程产生的碳排放量进行计算。结果表明:西安市航天中路机动车道材料生产过程产生的碳排放量占比最大;施工建造过程所产生的碳排放主要集中于柴油机械;碳排放因子对材料生产过程所产生的碳排放量影响较大;材料质量、运输距离是决定材料运输过程碳排放量的重要因素。Based on the theory of life cycle assessment,a carbon emission inventory was constructed during the construction phase of the Aerospace Middle Road motorway in Xi’an City.The carbon emission factor calculation method was used to calculate the carbon emissions generated during the construction,material production,and material transportation processes.The results indicate that the carbon emissions generated by the material production process account for the largest proportion;the carbon emissions generated during construction process are mainly concentrated in diesel machinery;the carbon emission factor has a significant impact on the carbon emissions generated during the material production process;material quality and transportation distance are important factors that determine the carbon emissions during material transportation process.
