摘　　要：根据生态环境部每月发布的城市空气质量状况通报,分析青岛市2013-2019年的空气质量状况及在通报城市中的排名情况,并探讨了六项污染物分指数的贡献。结果显示,青岛市空气质量综合指数呈现冬季高、夏季低的趋势,特别是1月、12月较高,2014年各月的综合指数较其他年份同期偏高。青岛市在通报城市中的排名差异较大,夏季排名靠前,冬季排名靠后。六项污染物分指数贡献率分析可得,秋冬季空气质量转差的主要原因是颗粒物贡献升高,夏季O3成为主要污染物,需有针对性进行污染管控。According to the monthly urban air quality reports issued by the Ministry of Ecology and Environment,the air quality status of Qingdao from 2013 to 2019 and its ranking among the notified cities were analyzed,and the contribution of six pollutant sub-indexes were discussed.The results indicated that the air quality composite index of Qingdao showed a trend of high in winter and low in summer,especially in January and December.The composite index of each month in 2014 was higher than that of other years.The ranking of Qingdao among the notified cities varied greatly,ranking forward in summer and backward in winter.According to the contribution rate of the sub-index of six pollutants,the main reason for worse air quality in autumn and winter was the contribution of particulate matter,and O3 becomes the main pollutant in summer.So the targeted pollution control was required.
