In order to prevent ozone pollution effectively

the time-space distribution characteristics of annual

seasonal

monthly and diurnal variations of ozone pollution in shangrao city were analyzed. The influence of the concentration of meteorological pollutants（PM10

PM2.5

NO

x

etc.）

topography and surrounding environment on ozone pollution was also studied. The results show that from 2017 to 2019

the annual ozone mass concentration in the central urban area of Shangrao first decreases and then increases. In terms of seasonal variation

ozone mass concentration is higher in summer and autumn than in spring and winter. In terms of diurnal variation

the ozone mass concentration began to rise at 8:00 in the morning

reached the p

eak at 14:00 at noon

and then gradually decreased. The ozone mass concentration is greatly affected by meteorological conditions. The ozone mass concentration is higher when the air temperature is higher and the light intensity and wind force is lower. The results provide theoretical support for the prevention and control of ozone pollution to improve the environmental air quality in Shangrao city.
