摘　　要：根据南京市环境监测站采集的污染物浓度数据,研究了2014年春节期间实行限燃措施下的空气质量变化特征,对比分析了城区和近郊的浓度变化差异,监测数据表明:春节前后20天内污染超标率控制在25%,PM2.5和PM10最大值均出现在除夕后半夜,SO2、NO2最大值稍超前或滞后于烟花爆竹的集中燃放期,O3质量浓度具有明显日变化并呈现白天高夜间低的特点,草场门测站与浦口测站PM2.5、PM10的浓度变化趋势基本一致,其差值反映了城郊污染物的累积存在区域差异,除夕0:00~2:00污染物浓度急剧增加并累积,元宵节晚间污染物浓度在19:00以后逐渐持续增加。Based on the pollutant concentration data collected by Nanjing environmental monitoring station, variation of air quality was studied during 2014 Spring Festival under the limitation regulation of firecrackers. The concentration difference between urban and suburb area was compared and analyzed. The pollutant standard-exceeding rate is kept in 25%during 20 days before and after the Spring Festival. The maximum concentrations of PM2.5 and PM10 appear after midnight of Chinese New Year＇s Eve. The maximum concentrations of SO2 and NO2 appear slightly ahead or behind the period of concentrated setting off firecrackers. O3 concentration has a significant diurnal variation, and is high in daytime and low at night. The concentration change trends of PM2.5 and PM10 are quite similar between Caochangmen monitoring station and Pukou monitoring station. The difference of concentration change reflects the regional diversity in the accumulation of pollutants between urban and suburb area. The pollutant concentration increases and accumulates rapidly from 0：00 to 2：00 on Chinese New Year＇s Eve. The pollutant concentration keeps increasing slowly after 19：00 on Lantern festival.
