摘　　要：为探究春节时期烟花爆竹的燃放对赣州市城区空气质量的影响,运用数理统计、GIS方法等对2017年春节期间赣州市通天岩、气象台、市图书馆、华坚鞋城和地委监测站的PM_(2.5)、PM_(10)、CO、NO_2、O_3_8 h、SO_2浓度数据进行分析,探讨烟花爆竹燃放对赣州市区空气质量的影响.结果表明:燃放烟花爆竹在短时间内会造成严重的空气污染,除夕夜间AQI达369,处于严重污染状态,其中对PM_(10)、PM_(2.5)和SO2的影响最为显著,颗粒物浓度急剧增加,PM_(2.5)和PM_(10)分别达到303μg/m^3和425μg/m^3.空间上AQI呈现城区内高,城区外低的分布,且除夕期间气象台、市图书馆、华坚鞋城和地委监测站空气质量严重超标,"破五"和元宵节时段烟花爆竹对赣州市城区空气质量污染不明显,总体为良状态.In order to explore the influence of fireworks on the air quality of Ganzhou City during the Spring Festival,statistical method and GIS method were used to analyze the air quality data including PM2.5,PM10,CO,NO2,O3_8 h,SO2 concentration data from Tongtianyan,weather station,city library,Huajian shoes town and prefectural monitoring stations measured during the 2017 Spring Festival.The results show that the fireworks could cause serious air pollution in a short time.AQI reached 369 in New Year＇s Eve and it was seriously polluted.The effect of PM10,PM2.5 and SO2 was the most significant,and the concentration of PM2.5 And PM10 reached 303 μg/m-3 and 425 μg/m-3,respectively.At the level of spatial distribution,AQI showed a high distribution in the inner city area and low in the outside,and the air pollution of the meteorological station,the city library,the Huajiang shoes town and prefectural monitoring stations during the New Year＇s Eve was seriously exceeded.Air pollution caused by ＂Powu＂ and the Lantern Festival fireworks in Ganzhou city is not obvious,showing a good state in a whole.
