Abstract： Near-surface ozone is a typical secondary pollutant of ambient air pollution and an important ecological monitoring object. By monitoring the ozone concentrations in five mountainous counties and three plain counties of Yichang City from 2017 to 2021， the annual， quarterly， monthly and daily changes of ozone were analyzed， and the temporal and spatial distribution of ozone was summarized， in order to provide reference for the prevention and control of ozone pollution in Yichang and other areas with the same situations.

Keywords： ozone; Yichang City; mountainous county; spatio-temporal distribution; pollution prevention and control

臭氧主要由氮氧化物、一氧化碳和挥发性有机物等在阳光下发生光化学反应生成，属于强氧化剂，达到一定浓度后会对人体健康、农作物生长、生态环境、城市建筑等造成极大危害[1-2]。（剩余3911字）
