摘　　要：利用昆明市2019年空气质量监测资料,对昆明市O_(3)浓度的时空分布特征进行了分析。发现呈贡、西山森林公园的O_(3)浓度达标天数最少,碧鸡广场的O_(3)浓度达标天数最多;各监测点的O_(3)-8h浓度变化范围相差不大,最小值出现在金鼎山,最大值出现在呈贡;O_(3)-8h年平均值最小出现在东风东路,最大出现在西山森林公园;各监测点O_(3)污染程度均为春季最严重,秋季和冬季最轻;O_(3)浓度没有表现出明显的周末效应。Based on the air quality monitoring data of Kunming City in 2019,the temporal and spatial distribution characteristics of O_(3) concentration in Kunming were analyzed.It was found that Chenggong and Xishan Forest Parks had the least days of O_(3) concentration up-to-standard,while Biji Square had the most.The O_(3)-8h concentration variation range of each monitoring point was not much different,the minimum value appeared in Jindingshan and the maximum value appeared in Chenggong.The annual average value of O_(3)-8h concentration was the smallest in Dongfengdonglu and the largest in Xishan Forest Park.The O_(3) pollution degree at each monitoring point was the most serious in spring,and the lightest in autumn and winter.There was no obvious weekend effect in O_(3) concentration.
