摘　　要：基于本地化修正的排放因子,建立了2018年河南省1 km分辨率网格化机动车污染物排放清单。2018年河南省机动车氮氧化物(NO_(x))、挥发性有机物(VOCs)、细颗粒物(PM_(2.5))、可吸入颗粒物(PM_(10))排放量分别为44.32万、12.25万、7583.5、8293.7 t。79.2%的VOCs排放来源于汽油车,其中小型汽油客车和摩托车分别贡献了74.3%、15.0%;柴油车是NO_(x)、PM_(2.5)、PM_(10)的主要排放源,其中重型柴油货车的NO_(x)、PM_(2.5)、PM_(10)排放较为突出,分别贡献了74.6%、43.2%、43.5%;国Ⅲ及国Ⅳ标准机动车成为污染物主要排放源,国Ⅲ标准机动车NO_(x)、VOCs、PM_(2.5)、PM_(10)贡献率分别为39.5%、20.3%、34.6%、35.2%,国Ⅳ标准机动车分别为48.6%、49.4%、31.4%、31.0%;不同城市机动车污染排放特征存在明显差异。河南省机动车污染物在空间中的分布存在明显的线形特征,中部与北部地区污染物排放强度最高,南部地区最低。Based on the emission factors modified by localization,the grid emission inventory of vehicles with the resolution of 1 km in Henan Province in 2018 was established.In 2018,the total emissions of NO_(x),VOCs,PM_(2.5) and PM_(10) from vehicles in Henan Province reached 4.432×10^(5),1.225×10^(5),7583.5 and 8293.7 t respectively.79.2%of VOCs came from gasoline vehicles,of which 74.3%were from light-duty gasoline vehicles and 15.0%from motorcycles;diesel vehicles were the main emission sources of NO_(x),PM_(2.5) and PM_(10),among which heavy-duty diesel trucks were the main contributor of NO_(x),PM_(2.5) and PM_(10),accounting for 74.6%,43.2%and 43.5%respectively;NationalⅢand NationalⅣstandard vehicles became the primary source of pollutants,with the contribution rate of NO_(x),VOCs,PM_(2.5) and PM_(10) were 39.5%,20.3%,34.6%and 35.2%for NationalⅢand 48.6%,49.4%,31.4%and 31.0%for NationalⅣstandard vehicles,respectively;characteristics of vehicle emission were diverse in different cities.The spatial distribution of vehicle pollutants in Henan Province had obvious linear characteristics.The emission intensity in the central and north region was the highest,with south region the lowest.
