摘  要：近地面臭氧是環(huán)境空氣污染的典型次生污染物，是重要的生態(tài)環(huán)境監(jiān)測(cè)對(duì)象。通過監(jiān)測(cè)宜昌市5個(gè)山區(qū)縣與3個(gè)平原縣2017—2021年臭氧濃度，分析臭氧隨年、季度、月、日變化，總結(jié)臭氧時(shí)空分布規(guī)律，以期對(duì)宜昌市及類似區(qū)域臭氧污染防控提供參考。

關(guān)鍵詞：臭氧；宜昌市；山區(qū)縣；時(shí)空分布；污染防控

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、一氧化碳和揮發(fā)性有機(jī)物等在陽(yáng)光下發(fā)生光化學(xué)反應(yīng)生成，屬于強(qiáng)氧化劑，達(dá)到一定濃度后會(huì)對(duì)人體健康、農(nóng)作物生長(zhǎng)、生態(tài)環(huán)境、城市建筑等造成極大危害[1-2]。（剩余3911字）
