摘要
通过van Aerde速度-流量模型模拟和交通流量调查获取了阳泉市路网的车流量、车型构成和车速基础数据,利用自下而上的方法,基于实际交通流量数据、机动车排放因子和路段,构建了阳泉市道路机动车排放清单,并分析了机动车污染物排放特征。结果表明:2017年阳泉市道路机动车排放的CO、HC、NO_(x)、PM分别为4.56×10^(4)、0.96×10^(4)、1.76×10^(4)、0.024×10^(4) t。按道路类型划分,高速公路(含城市快速路)机动车污染物排放量较大,CO、HC、NO_(x)、PM排放量分别占排放总量的48.4%、48.9%、40.0%和34.3%;按车辆类型划分,小型客车是CO、HC排放的主要贡献者,重型货车是NO_(x)、PM排放的主要贡献者;按排放阶段划分,国4机动车排放的CO和HC占比较高,国3机动车排放的NO_(x)和PM占比较高;按区县划分,污染物排放量最大的为盂县,其次是平定县和郊区。机动车在道路上的实际排放量与道路类型、道路所属行政区域及车辆类型密切相关。
The basic data of traffic flow,vehicle type and vehicle speed of road network in Yangquan City were obtained through the simulation by van Aerde speed-traffic flow model and the traffic flow survey.Based on the actual road traffic flow data,vehicle emission factors and road sections,the emission inventory of motor vehicle of Yangquan City was constructed by using the bottom-up method,and the emission characteristics of vehicle exhaust were analyzed.The results showed that the emissions of CO,HC,NO_(x) and PM from the road vehicles in the city in 2017 was 4.56×10^(4),0.96×10^(4),1.76×10^(4) and 0.024×10^(4) t,respectively.According to road category,the highway(including urban expressway)was the main contributor of CO,HC,NO_(x) and PM,accounting for 48.4%,48.9%,40.0%and 34.3%of total emissions respectively.In terms of vehicle type,car was the main contributor of CO and HC emission and heavy truck was the main contributor of NO_(x) and PM emission.Based on emission stages,vehicles of national stage 4 emitted the main proportion of CO and HC,vehicles of national stage 3 emitted the highest proportion of NO_(x) and PM.In the view of geographical distribution,Yu County was the largest pollutants emission area,followed by Pingding County and suburbs.The research showed that the actual emissions of motor vehicles on the road were closely related to the road category,the administrative region of the road and the vehicle type.
