【摘要】：利用本地化修正的MOVES模型模擬確定了關中地區(qū)不同類型車輛的顆粒物排放因子,結(jié)合實地調(diào)研的保有量和行駛里程數(shù)據(jù)測算了該地區(qū)的機動車顆粒物年排放總量并從季節(jié)、城市、車型和燃油等多個角度詳細分析了顆粒物的排放分擔率。結(jié)果表明:關中地區(qū)2012年的機動車顆粒物排放總量分別為PM_(2.5)4.06×1O~3 t,PM_(10)5.52×10_3 t;關中五市一區(qū)中西安市的顆粒物排放量最高PM_(2.5)和PM_(10)。排放分R%占到該地區(qū)的46.53%和48.39%;不同類型車輛中重型貨車的排放分擔率最高其次為中型貨車二者之和占到顆粒物總排放的50%以上;不同燃油車輛中,柴油車的排放分擔率遠遠高于汽油車,是顆粒物的主要貢獻者;因此中型和重型柴油貨車是關中地區(qū)控制顆粒物排放污染的重點車型。
[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.
