摘　　要：近年来,呼和浩特市机动车保有量迅速增加,机动车尾气对大气污染的影响越来越大。通过分析呼和浩特市机动车尾气污染情况,测算2012-2013年本市汽车尾气分担率,量化污染贡献。结果表明,大气污染加剧受机动车尾气排放增加的影响,汽油轿车已成为本市机动车污染物排放的主要污染车型,其排放量占所有机动车CO、NO_x、HC排放量的89.89%、50.90%、80.73%。In recent years, the number of motor vehicles in Hohhot has increased rapidly, and the impact of motor vehicle exhaust on atmospheric pollution is increasing. By analyzing the current situation of motor vehicle exhaust pollution in Hohhot, the city's automobile tail gas sharing rate is measured from 2012 to 2013, and the pollution contribution is quantified. The results show that the increase in air pollution is affected by the increase in vehicle exhaust emissions. Gasoline cars have become the main polluting vehicle emissions of motor vehicles in this city, and their emissions account for 89.89%, 50.90%, and 80.73% of the CO, NOx, and HC emissions of all motor vehicles, respectively.
