摘要
实现交通领域CO_(2)和大气污染物协同控制是促进区域可持续发展的重要途径。该研究以广州市为例,在分析交通领域2010-2019年排放特征基础上,采用情景分析的方法,利用减排量弹性系数和协同控制效应坐标,系统分析了交通领域16项减排措施的CO_(2)和大气污染物协同控制效应。研究结果表明:(1)发展水路货运、高速铁路以及公共交通等运输结构低碳化类措施具有最大的减排潜力和协同控制效应,是交通领域实现减排最重要的选择;(2)能效提升类措施能同时实现CO_(2)和大气污染物减排,也是实现交通领域减排的重要路径;(3)能源结构清洁化类措施中,提高电动化率措施的减排潜力和协同控制效应最好,是交通领域能源转型的主要方向;推广生物燃油和氢能措施有赖于技术的突破和大规模推广应用;推广天然气使用措施会增加CO和HC排放,不具有协同控制效应,需要配合使用大气污染物末端脱除装置。
The coordinated control of CO_(2)and air pollutants in transport sector is an important way to promote regional sustainable development.Taking Guangzhou as the case city,this study first analyzed the emission characteristics of the transport sector from 2010 to 2019,then systematically analyzed the co-control effects of CO_(2)and air pollutants in 16 typical emission reduction measures in transport sector by using scenario analysis method.The elasticity coefficient and coordinate system analysis methods are used to identify and evaluate the co-control effects of measures.The research results show that the transportation structure optimization measures,such as the development of waterway freight,high-speed railway,and public transportation,have the greatest emission reduction potential and best emission co-control effects,which are the most important choice for the transport sector to reduce CO_(2)and air pollutants in the future.Energy efficiency improvement measures can simultaneously reduce CO_(2)and air pollutants emissions,and is also an important path to achieve emission reduction in the transport sector.For the energy structure optimization measures,increasing the electricity rate has the greatest emission reduction potential and best emission co-control effects,which is the main direction of the energy transition in the transport sector.The promotion of biofuel and hydrogen energy in the transport sector depends on technological breakthroughs and large-scale promotion application.The promotion of natural gas in the transport sector will increase CO and HC emissions,and have no emission co-control effects.It is necessary to cooperate with the use of air pollutant terminal removal devices.
