红河州机动车污染物排放特征研究

Study on the Emission Characteristics of Vehicle Pollutants in Honghe Prefecture

基于《道路机动车大气污染物排放清单编制技术指南》建立了红河州2019年机动车排放清单。结果表明:2019年红河州CO、HC、NOx、PM 2.5、PM 10和SO 2排放总量分别为29494、11908、13259、273、301和138t/a。机动车污染物分担率差别显著,小型汽油载客车、轻型汽油载货车和摩托车是CO的主要排放来源,小型汽油载客车和摩托车对HC排放贡献最大,对NOx、PM 2.5和PM 10贡献最大的是大型柴油载货车。汽油车是CO和HC机动车污染物排放的主要贡献源,其排放量分别占排放总量的82.01%和96.64%,柴油车是NOx、PM 2.5和PM10的主要贡献源。

Based on the technical guide for the compilation of the road vehicle air pollutant emission list,the vehicle emission list of Honghe Prefecture in 2019 was established.The results showed that the total emissions of CO,HC,NOx,PM 2.5,PM 10 and SO 2 in Honghe were 29494 tons,11908 tons,13259 tons,273 tons,301 tons and 138 tons,respectively.There was a significant difference in vehicle pollutant sharing rate.Small gasoline passenger cars,light gasoline trucks,and motorcycles were the main sources of CO emissions.Small gasoline passenger cars and motorcycles contributed the most to HC emissions,while large diesel trucks contributed the most to NOx,PM 2.5 and PM 10.Gasoline vehicle was the main contribution source of CO and HC vehicle emissions,accounting for 82.01%and 96.64%of the total emissions,respectively.Diesel vehicle was the main contribution source of NOx,PM 2.5 and PM 10.
