摘　　要：本文对锡林浩特市2023年春节期间燃放烟花爆竹对周边环境的影响进行分析研究。结果表明:集中燃放烟花爆竹对城市环境空气质量造成了严重影响,在集中燃放期PM_(10)、PM_(2.5)和PM_(1.0)质量浓度迅速升高,分别比燃放前平均速率增加54%、75%和91%,在除夕夜零点左右达到最高,分别为348.4μg/m^(3)、235.4μg/m^(3)、167.8μg/m^(3);在整个春节燃放期PM10质量浓度呈现低—高—低—高的变化趋势,PM_(2.5)、PM_(1.0)质量浓度呈现低—高—低的变化趋势;在集中燃放期不利的气象条件使空气中的污染物无法快速消散,短时对空气质量造成严重影响。This paper analyzes the impact of setting off fireworks and firecrackers during the 2023 Spring Festival in Xilinhot City on the surrounding environment.The results show that the concentrated setting off of fireworks and firecrackers severely impacted urban environmental air quality.During the concentrated setting off period,the mass concentrations of PM_(10),PM_(2.5),and PM_(1.0)rapidly increased by 54%,75%,and 91%respectively compared to the average rate before setting off,reaching their highest levels around midnight on New Year's Eve at 348.4μg/m^(3),235.4μg/m^(3),and 167.8μg/m^(3)respectively.Throughout the Spring Festival,the mass concentration of PM10 showed a low-high-low-high trend,while the mass concentrations of PM_(2.5)and PM_(1.0)showed a low-high-low trend.Adverse meteorological conditions during the concentrated discharge period prevented the rapid dissipation of pollutants in the air,causing a serious impact on air quality in the short t erm.
