摘　　要：利用北京市87个噪声自动监测站点监测数据,分析2018年除夕夜(2月15日18:00—2月16日2:00)全市噪声排放水平。通过比较2013—2018年除夕夜噪声排放强度,结合北京市细颗粒物浓度变化分析,表明2018年除夕夜北京市噪声污染排放显著降低,2013—2018年噪声污染排放存在时空分布特征,除夕夜细颗粒物污染变化与噪声污染变化趋势较为吻合,作为主要污染源的烟花爆竹燃放在受到政策的限制后,除夕夜北京市声环境和空气环境同比大幅改善。According to the monitoring data from 87 noise automatic monitoring stations in Beijing,the noise emission level on New Year s Eve(February 15th,18:00—February 16th,2:00)were analyzed.By comparison the noise emission intensity and fine particulate concentration on New Year s Eve during 2013 to 2018 in Beijing,the results showed that the noise pollution emission was significantly decreased on New Year s Eve in 2018,there were spatial and temporal distribution characteristics of noise pollution from 2013 to 2018.The variations of fine particulate concentration and noise pollution on New Year s Eve were consistent.For the restriction of fireworks and firecrackers which were the main pollution sources,air and acoustic environment in Beijing were improved significantly on New Year s Eve.
