摘要

摘要: 机动车大气污染物及CO₂减排对于改善空气质量和缓解气候变化具有重要的作用。综合利用北京市机动车保有量、道路行驶工况、气象、燃料组分及燃料消耗量等数据,应用COPERT模型计算得到北京市机动车主要大气污染物和CO₂排放量,并识别其污染排放特征和不同车型、排放标准等级车辆的排放贡献,采用ADMS-Urban模型模拟了机动车污染排放对周边环境的影响。结果表明:2019年北京市机动车4项主要大气污染物CO、NO_x、PM_2.5和VOCs排放量分别为12.15万、4.06万、0.18万和2.57万t。车辆结构得到优化,国四及以上排放标准车辆占比达86.97%,数量占4%的柴油客货车排放贡献大,分别占机动车NO_x和PM_2.5排放总量的84%和60%;非末端排放占机动车VOCs排放量的20%,需要引起关注。机动车尾气排放对5个交通监测站点贡献的NO₂平均浓度为15.7 μg/m³,其对环境质量影响较大;机动车CO₂排放量为1 683万t,其中柴油车排放贡献约21%。对北京市机动车大气污染物和碳排放需要进一步协同控制。

Abstract: Air pollutants and carbon dioxide (CO₂) emissions reduction from motor vehicles play an important role in improving air quality and mitigating climate change. The data of vehicle population, road-driving conditions, meteorological, fuel composition and fuel consumption were comprehensively used to calculate the main air pollutants and CO₂ emissions of motor vehicles in Beijing based on COPERT Model. The emission characteristics, emission contribution of the vehicles of different types, and emission standard levels were identified. Urban-ADMS model was used to simulate and quantify the effect on surrounding environment by motor vehicles. The results showed that: the emissions of CO, NO_x, PM_2.5 and VOCs from motor vehicles of Beijing was 121 500, 40 600, 1 800 and 25 700 tons, respectively, in 2019. The structure of vehicles had been optimized. Vehicles with National IV and above standards accounted for 86.97%. Diesel passenger and freight vehicles accounting for 4% contributed greatly to the emissions, accounting for 84% and 60% of the total emissions of NO_x and PM_2.5, respectively. Evaporative emissions from gasoline vehicles accounted for 20% of VOCs emissions from motor vehicles, which required attention. Vehicle exhaust emissions contributed 15.7 μg/m³ to the average NO₂ concentration at five traffic monitoring stations which had a great impact on air quality. CO₂ emissions of motor vehicles were 16.83 million tons, of which diesel vehicle emissions contributed about 21%. Air pollutants and carbon emissions of motor vehicles need further coordinated control.
