摘　　要：为了解咸宁市近年来环境空气质量状况,选取2018年1月至2022年12月咸宁市城区空气质量国控点每小时监测数据,分析空气质量状况,找出存在的问题,为管理部门开展污染防治工作提供参考依据。结果表明:2018~2022年,咸宁市城区空气质量总体向好,PM_(2.5)浓度及其空气质量分指数呈显著下降趋势,空气质量优良率呈不显著上升趋势,PM_(10)、SO_(2)、NO_(2)、CO和O_(3)浓度及其空气质量分指数变化趋势不显著。细颗粒物(PM_(2.5))和臭氧(O_(3))是造成咸宁市城市空气质量出现污染天气和影响城市空气质量的主要污染物。为此,提出了从强化扬尘污染管控、工业污染防治和机动车尾气监管方面精准发力,落实大气污染防治措施的建议。In order to understand the environmental air quality situation in Xianning City in recent years,hourly monitoring data from the national air quality control points in the urban area of Xianning City from January 2018 to December 2022 were selected to analyze the air quality situation in Xianning City,identify existing problems,and provide a reference basis for management departments to carry out pollution prevention and control work.The study showed that during the period from 2018 to 2022,the overall urban air quality in Xianning City has improved,with a significant downward trend in PM_(2.5)concentration and its air quality sub index,a non-significant upward trend in air quality excellence rate,and a non-significant change trend in PM_(10),SO_(2),NO_(2),CO,and O_(3)concentration and its air quality sub index.Fine particulate matter(PM_(2.5))and ozone(O_(3))are the main pollutants that cause polluted weather and affect urban air quality in Xianning City.According to the actual situation of the city,precise efforts will be made to strengthen the control of dust pollution,the prevention and control of industry pollution and the supervision of motor vehicle exhaust,in order to implement air pollution prevention and control measures.
