摘　　要：为了解安阳市春节期间烟花爆竹对空气质量的影响,选取2020—2022年连续三年除夕夜时段,基于安阳市空气站点数据及气溶胶激光雷达数据进行综合分析,结果表明:2020—2021年除夕夜各项参数表征是由烟花爆竹排放导致。2022年除夕夜空气站点各项参数因子并未受到烟花爆竹影响。气溶胶激光雷达数据表明:2020年至2021年初一时段均受到外来传输的影响,传输高度在800米以内,且根据空气站数据分析得出传输源解析为烟花爆竹导致。2020年初一时段传输来源为偏北方位,2021年初一时段传输来源为偏东南方位,2022年主要以偏西北气流为主,并未受到显著外来传输的影响。综合各种类型数据表明:2020年至2022年连续三年禁燃禁放措施执行力度以及效果十分显著。In order to understand the impact offireworks andfirecrackers on air quality during the Spring Festival in Anyang City,a comprehensive analysis was conducted based on air station data and aerosol LiDAR data for three consecutive years from 2020 to 2022 on New Year’s Eve.The results showed that the characterization of various parameters on New Year’s Eve from 2020 to 2021 was caused by the emissions offireworks andfirecrackers.The various parameter factors of the air station on New Year’s Eve in 2022 were not affected byfireworks andfirecrackers.The aerosol LiDAR data shows that from 2020 to early 2021,the transmission was affected by external transmission,with transmission heights within 800 meters.According to the analysis of air station data,the transmission source was analyzed to be caused byfireworks andfirecrackers.The transmission source for thefirst period of early 2020 is from a northerly direction,while the transmission source for thefirst period of early 2021 is from a southeastern direction,in 2022,the main airflow will be towards the northwest and will not be significantly affected by external transmission.Based on various types of data,it is evident that the implementation and effectiveness of the three consecutive years of fuel and gas ban measures from 2020 to 2022 have been significant.
