| 摘 要： | 利用2009年-2011年春节期间大同市可吸入颗粒物PM10质量浓度和气象资料，分析了烟花爆竹燃放后对空气质量的影响。春节期间在大量烟花爆竹集中燃放时，当有降雪天气出现时，降雪对PM10质量浓度的上升具有明显的抑制作用；在没有降雪天气时，风速仍是影响PM10质量浓度的主要因素。除夕的11时-13时、23时-Ol时，元宵节的18时-21时这三个时段为PM10质量浓度最大的时段，其间PM10质量浓度很高。当天气稳定风速较小时PM0质量浓度会明显升高。在集中燃放烟花爆竹后，当风速较大存在有利扩散的气象条件时，PM10质量浓度升高后很快降低，没有太多的污染，而当天气稳定风速较小时，PM0质量浓度升高较明显，对空气污染严重。

| Abstract: | Based on the PM10 mass concentration and meteorological data from 2009 to 2011 during the Spring Festival in Datong, the air quality was analyzed after firework discharging. During a large number of fireworks discharging in Spring Festival, snowfall would inhibit the PMlo mass concentration and the wind speed is the main factors which affect the PM10 mass concentration. The PM10 mass concentration is the greatest in 11：00AM-1：00PM, 11：00PM-1：00AM in Spring Festival Eve and in 6：00PM - 9：00PM in Lantern Festival |
