【摘要】：利用本地化修正的MOVES模型模拟确定了关中地区不同类型车辆的颗粒物排放因子,结合实地调研的保有量和行驶里程数据测算了该地区的机动车颗粒物年排放总量并从季节、城市、车型和燃油等多个角度详细分析了颗粒物的排放分担率。结果表明:关中地区2012年的机动车颗粒物排放总量分别为PM_(2.5)4.06×1O~3 t,PM_(10)5.52×10_3 t;关中五市一区中西安市的颗粒物排放量最高PM_(2.5)和PM_(10)。排放分R%占到该地区的46.53%和48.39%;不同类型车辆中重型货车的排放分担率最高其次为中型货车二者之和占到颗粒物总排放的50%以上;不同燃油车辆中,柴油车的排放分担率远远高于汽油车,是颗粒物的主要贡献者;因此中型和重型柴油货车是关中地区控制颗粒物排放污染的重点车型。
[Abstract]:The particulates emission factors of different types of vehicles in Guanzhong area were determined by using localized modified Moves model. Combined with the data of field investigation and driving mileage, the total annual emission of particulate matter in this area was calculated and analyzed from season to season. The emission sharing rate of particulate matter is analyzed in detail from several angles, such as city, vehicle and fuel. The results showed that the total emission of particulate matter in Guanzhong area in 2012 was PM2.5 4.06 脳 1OO3 t PM10 5.52 脳 103t, and the highest PM _ (2.5) and PM10 _ (10) in Zhongxi'an city of Guanzhong five cities in 2012. The emission fraction R% accounted for 46.53% and 48.39% of the total emissions in the area; the highest emission sharing rate of heavy goods vehicles in different types of vehicles was over 50% of the total particulate matter emissions of medium goods vehicles; and among different fuel vehicles, The emission sharing rate of diesel vehicles is much higher than that of gasoline vehicles, which is the main contributor of particulate matter, so medium and heavy diesel trucks are the key vehicles to control particulate pollution in Guanzhong area.
