泉州市"十二五"期间机动车污染物排放特征研究

建立了泉州市"十二五"期间机动车排放清单,获得了不同机动车排放贡献率.结果表明:摩托车和小型客车占总机动车保有量的比例最大,成为泉州市机动车排放的主要来源;污染物排放量排序:CO>NOx>HC>PM;甲醛>苯>乙醛>1,3-丁二烯>氨;CO2>N2O>CH2;不同车型对机动车污染物的排放贡献率有显著不同,小型客车对于CO和HC排放贡献最大,NOx、PM的主要排放源为重型货车;摩托车、小型客车、中型货车对有毒有害物的贡献率最大;小型客车对温室气体的贡献率最大.

Vehicle Exhaust Emission Characteristicsin Quanzhou City during Twelfth Five-year Plan

A vehicle emission inventory was developed for the Quanzhou city during Twelfth Five-year Plan Period.The inventory was used to analyze the contribution from different vehicle types to the total vehicular emission in Quanzhou city.The results show:(1)Motorcycles and mini-bus vehicles made up the largest population proportion of vehicles, and were the main sources of vehicle emission;(2)The order of pollutant discharge were CO>NOx>HC>PM, formaldehyde> benzene>acetaldehyde>1,3-butadiene>ammonia, CO2>N2O>CH2;(3)There were significant differences in the emission contribution among different vehicle types, mini-bus were the major CO and CH emissions contributor;the heavy-duty trucks had the largest contribution rates of NOx, PM2.5, PM10.Motorcycle, mini-bus and medium trucks were the main source of poisonous and harmful pollutants;mini-bus was the vehicle type, which contributed the largest for greenhouse gases.
