摘　　要：基于2015年-2023年春节空气质量监测数据,分析烟花爆竹燃放对县域城市空气质量影响。结果表明:2015年-2023年春节期间,烟花爆竹燃放对兰溪市城区空气质量影响显著,集中燃放时间段对PM_(10)、PM_(2.5)日均值最大贡献率分别为51.6%、50.7%;2023年春节期间,集中燃放期对PM_(10)、PM_(2.5)、SO_(2)小时值贡献率分别为51.9%、46.7%、31.4%,非集中燃放期对PM_(10)、PM_(2.5)、SO_(2)小时值贡献率分别为22.3%、26.1%、4%,烟花爆竹燃放造成O3小时值降低,造成PM_(2.5)中Cu^(2+)、Ba^(2+)、K^(+)、Cl^(-)等水溶性离子含量快速上升,其中Cu^(2+)影响最为显著,短时上升54.73倍。Based on the air quality monitoring data during the Spring Festival from 2015 to 2023,this study analyzes the impact of fireworks and firecrackers on the air quality of county-level cities.The results indicate that during the Spring Festival period from 2015 to 2023,the burning of fireworks and firecrackers significantly affected the air quality in the urban area of Lanxi City.The maximum contribution rates of concentrated burning periods to the daily average values of PM_(10)and PM_(2.5)were 51.6%and 50.7%,respectively.During the Spring Festival period in 2023,the contribution rates of concentrated burning periods to the hourly values of PM_(10),PM_(2.5),and SO_(2) were 51.9%,46.7%,and 31.4%,respectively.The contribution rates of non-concentrated burning periods to the hourly values of PM_(10),PM_(2.5),and SO_(2) were 22.3%,26.1%,and 4%,respectively.The burning of fireworks and firecrackers caused a decrease in O 3 hourly values and a rapid increase in the content of water-soluble ions such as Cu^(2+),Ba^(2+),K^(+),and Cl^(-)in PM_(2.5),with Cu^(2+)showing the most significant impact,increasing by 54.73 times in a short period.
