摘 要:为研究石家庄市臭氧污染特征及气象因素对臭氧污染的影响,对2017—2020年石家庄市环境空气质量监测国控站点臭氧监测数据和气象数据进行研究分析.结果表明,2017—2020年石家庄市全年臭氧每日最大8h滑动平均值的第90百分位数分别为198,204,226,186μg/m^(3).2017—2019年臭氧污染整体呈加重趋势.2017年,以臭氧为首要污染物的天数在总污染天数中的占比为25%,2020年这个数值达到40%.臭氧8h质量浓度季度变化特征为夏秋季高、春冬季低,主要污染天主要出现在5~9月.气象因素中,高温低湿天气是臭氧高值的高发期,臭氧质量浓度受到偏南风和偏东风的明显影响.In order to study the characteristics of ozone pollution and the influence of meteorological factors on ozone pollution in Shijiazhuang city,the ozone(O;)monitoring data and meteorological data in Shijiazhuang national control ambient air monitoring stations from 2017 to 2020 are used to analyze and study.The results show that:from 2017 to 2020,the O_(3)-8 h-90th percentile in the ambient air of Shijiazhuang city is 198,204,226 and 186μg/m^(3)respectively.From 2017 to 2019,the overall trend of ozone pollution in recent years is increasing.The proportion of days with ozone as the primary pollutant in the total pollution days has increased from 25%in 2017 to 40%in 2020.The concentration of ozone is high in summer and autumn,low in spring and winter,and the main pollution days are from May to September.Among the meteorological factors,high temperature and low humidity weather is the high value and high incidence period of Os,and O concentration is obviously affected by southerly wind and easterly wind.
