摘　　要：为了更加清楚地掌握臭氧变化规律,对2015年云南16个城市的臭氧监测数据进行了分析.结果表明:云南省空气质量的优良率达到了98.9%,全年的空气质量基本都保持维持一个相对较好的状况,16个城市中首要污染物为O_3-8 h的天数占总污染天数的46.3%;臭氧浓度最高的月份为5月,其次为3月和4月;臭氧浓度变化有明显的周末效应,除景洪及大理2个城市以外,其余14个城市臭氧浓度在周末均高于工作日;臭氧小时平均浓度在一天中呈单峰型变化规律,最低值出现在08:00—09:00,最大值出现在16:00—17:00.To investigate the regulations of ozone concentration change, we have used monitoring data of o- zone in the 16 cities of Yunnan in 2015.The results show that the fine rate of air quality in Yunnan Province reached 98.9% ,and the whole air quality maintained a good condition.Ozone as the primary pollutant days ac- counted for 46.3% of the whole polluted days. The highest ozone concentration appeared in May,followed by March and April.Ozone concentration changes have a significant effect on the weekends.Ozone concentration over the weekend is higher than that the working day except in Jinghong and Dali.The average concentration of 03-8 h in one day showed an unimodal curve, with the minimum value appeared at 8：00--9：00 and the maximum val- ue appeared at 16：00--17：00.
