选取夏季6-7月份环境空气质量监测数据及气象参数,分析了盐城市区夏季臭氧浓度变化规律及其影响因素.结果表明,O3浓度日变化特征显著,午后15:00左右出现最高值,早晨7:00左右浓度出现最低值,不同季节污染物的浓度变化存在差异,其小时浓度变化与NO2、NOX和CO呈此消彼长关系,白天,与NO2、NOX和CO有较好的负相关性,与气象参数气温、风速(>1.0m/s)和湿度呈现很好的相关性.

The data of environment monitoring of ambient air and meteorological parameters in june and July was selected to analyse the change rule and influence factors of ozone concentration of YanCheng city in summer. The Results showed that the daily concentration of O3 Changes significantly,it peaked at the afternoon around 15:00 and reached the lowest point around 7:00 in the morning.Variation characteristics of pollutant levels was different in each season. The hour concentration of O3 changed in the opposite direction of NO2,NOX and CO concentration. The hour concentration of O3 had good negative correlation with NO2, NOX and CO concentration during the day. And it also showed good correlation with the meteorological parameters , such as temperature,wind speed (>1.0 m/s) and humidity .
