摘　　要：为掌握滨海城市环境空气质量变化特征,为污染精准管控和打赢蓝天保卫战提供科学参考,以沿海重要中心城市青岛市为研究区域,基于青岛市9个国控空气监测点位监测结果,对2013—2019年青岛市6项空气污染物浓度监测结果进行分析,总结归纳青岛市空气质量时间变化特征。结果表明:2019年,青岛市空气质量超标,超标指标为颗粒物;青岛市2014年空气质量最差,2018年空气质量最好;2013—2019年,青岛市O3浓度总体呈上升趋势,其余5项污染物浓度呈下降趋势;青岛市环境空气主要污染物是PM2.5,其次是O3;青岛市空气质量冬季差于其他季节,春节期间烟花爆竹燃放等人为活动使空气质量变差。In order to grasp the change characteristics of ambient air quality in coastal cities,provide scientific reference for precise control of pollution and for winning the blue sky battle,taking Qingdao,an important coastal city as the study area,based on the monitoring results of nine national air monitoring points in Qingdao,the monitoring results of six air pollutants concentrations from 2013 to 2019 were analyzed to summarize the temporal variation characteristics of local air quality.The results showed that the air quality of Qingdao exceeded the standard in 2019,and the exceeding index was particulate matter.Qingdao had the worst air quality in 2014 and the best air quality in 2018.From 2013 to 2019,the concentration of O3 in Qingdao showed an overall upward trend,while the concentrations of the remaining five pollutants showed a downward trend.The main air pollutant in Qingdao was PM2.5,followed by O3.The air quality in Qingdao was worse in winter than that in other seasons.During the Spring Festival,man-made activities such as setting off fireworks and firecrackers make the air quality worse.
