摘　　要：为提升环境空气质量,有效治理大气污染,实现人与自然的和谐发展,以安溪县环境监测站2018—2020年空气自动监测站监测数据为研究对象,结合安溪县城区地理位置、产业布局等因素,分析了PM_(10)、PM_(2.5)、O_(3)浓度纵向(年度)变化趋势及月均浓度变化趋势,探讨了不同季节大气颗粒物、臭氧污染成因。结果表明,安溪县2018—2020年城区环境空气质量综合指数分别为3.32、2.77、2.44。O_(3)污染集中在4月、9月,PM_(2.5)污染集中在1月、2月。可通过加大城区道路保洁、环境卫生综合整治、施工场地扬尘治理等方式加以控制,进一步提升城区环境空气质量,为安溪县人们居住环境提供有力保障。In order to improve the ambient air quality,effectively control air pollution and realize the harmonious development between man and nature,taking the monitoring data of the automatic air monitoring station of Anxi County environmental monitoring station from 2018 to 2020 as the research object,combined with the geographical location and industrial layout of Anxi County,PM_(10),PM _(2.5) and O_(3) are analyzed.The longitudinal(annual)variation trend of O_(3) concentration and the variation trend of monthly average concentration,and the causes of atmospheric particulate matter and ozone pollution in different seasons are discussed.The results show that the comprehensive index of ambient air quality in the urban area of Anxi County from 2018 to 2020 is 3.32,2.77 and 2.44 respectively.O_(3) pollution is concentrated in April and September,The pollution of PM_(2.5) is concentrated in January and February.It can be controlled by increasing the urban road cleaning,comprehensive improvement of environmental sanitation and dust control of construction site,so as to further improve the urban ambient air quality and provide a strong guarantee for the people’s living environment in Anxi County.
