摘　　要：采用2018-01~2019-02武汉市气象数据以及污染物监测数据,分析了武汉市O3污染的时空分布特征,研究了O3与气象要素以及其他大气污染物之间的相关性。Based on the meteorological data and pollutant monitoring data of Wuhan from January 2018 to February 2019, this paper analyzes the spatial and temporal distribution characteristics of ozone pollution in Wuhan, and studies the correlation between ozone and meteorological elements and other atmospheric pollutants.The results show that:The peak period of the average concentration of O3 and the number of days exceeding the standard is April to October, and the peak occurs in June. From the daily distribution, the concentration of O3 in one day presents a "single peak" characteristic, which is higher in daytime than at night, and the peak occurs around 14 o’clock. The high concentration area of O3 in Wuhan is concentrated in the north, east, northeast and southwest corner, and the concentration of O3 in suburbs is generally higher than that in urban areas. The concentration of Wuhan O3 is positively correlated with sunshine duration and temperature, but negatively correlated with wind speed, relative humidity, NO2, CO, PM2.5 and PM10.
