| 基于机动车主要污染物排放量计算方法,对主要污染物排放因子进行识别与修正,建立沈阳市机动车污染物排放清单。结果表明:沈阳市机动车污染物的排放总量为206 804.3 t, CO、NOx、HC和PM10的排放量分别为128 500.4 t、44 206.3 t、32 104.8 t和1 992.8 t；机动车排放的各污染物二环以内的排放量占总量70.0%以上，和平区、沈河区和铁西区是该市机动车污染物高排放区域；小型客车和出租车对CO、HC的排放分担率较高,重型货车和轻型货车是NOx、PM10的主要排放源；沈阳市机动车污染物主要来自汽油车和柴油车,新能源机动车排放量较低。 |

| The vehicle emission inventory was established by identifying and correcting the main emission factors and calculating the main emissions in Shenyang. The results showed that the total emissions in Shenyang was 206 804.3 t, and the emissions of CO, NOx, HC and PM10 were 128 500.4 t, 44 206.3 t, 32 104.8 t and 1 992.8 t， respectively. The vehicle emissions within the second ring road contributed more than 70% of the total. Heping District, Shenhe District and Tiexi District were the high vehicle emission areas in Shenyang. Small passenger buses and taxis contributed most CO and HC emission. Heavy trucks and light trucks were the main contributors for NOx and PM10 emission. The pollutants mainly came from gasoline and diesel vehicles. New energy vehicles emission were relatively low. |
