  • 摘要: 为了解银川市2018年春节期间烟花爆竹燃放对空气质量的影响，分析了2016-2018年春节期间、2018年烟花爆竹禁放区与非禁放区以及2018年春节期间污染时段和非污染时段空气质量变化情况.并利用银川市大气超级监测网络的在线观测数据，对颗粒物中的水溶性离子、黑碳（BC）以及区域污染传输情况进行了分析.分析结果表明，与2016年和2017年春节期间同期比较，2018年优良天数同比分别增加4d、2d.除O3外，其它5项参数整体均呈下降趋势，空气质量改善幅度较大；银川市城区禁放区空气质量较好于周边非禁放区域；春节期间银川市城区PM10、PM2.5、SO2、NO2、CO日均浓度在污染时段（除夕至初二）明显高于非污染时段（初三至初六），分别高出65.2%、90.8%、68.4%、58.2%、67.7%，PM2.5/PM10的日均浓度比值在初一最大，为68.6%；污染时段与非污染时段相比，K+日均浓度增幅最大，达到了361.0%；污染时段PM10中的BC日均浓度较非污染时段上升85.2%，春节期间BC与CO小时浓度呈正相关、相关系数为0.73；气溶胶激光雷达监测图显示，春节期间空气质量主要以本地污染为主.
    Abstract: To realize the influence of fireworks and firecrackers on air quality during the Spring Festival in Yinchuan, air quality was analyzed during the Spring Festival from 2016 to 2018. Moreover, the air quality of no-fireworks and fireworks areas, pollution and non-pollution period were analyzed during the Spring Festival 2018. The online observation data including water soluble ions, black carbon(BC) and regional pollution transmission of particulate matter were obtained and analyzed by Yinchuan atmospheric Super monitoring network. The results showed that the number of excellent days in 2018 increased by 4 days (compared with 2016) and 2 days (compared with 2017) during the Spring Festival. Except for O3, the other five parameters were generally declined, and the air quality improved greatly. The air quality in firework areas of Yinchuan was better than that of surrounding non-fireworks areas. In the Spring Festival, the daily mean concentrations of PM10, PM2.5, SO2, NO2 and CO during pollution period (New Year's Eve to the second day) in Yinchuan were significantly higher than those of the non-pollution period (day three to six), and the values were greater than 65.2%, 90.8%, 68.4%, 58.2% and 67.7%, respectively. The maximum daily mean concentration ratio of PM2.5/PM10 was 68.6% in the first day of the lunar year. Compared with the non-pollution period, the daily mean concentration of K+ had biggest increase and reached to 361.0%. Moreover, the daily mean concentration of BC in PM10 during the pollution period increased by 85.2%. During the Spring Festival, the hour concentrations of BC and CO were positively correlated, and the correlation coefficient was 0.73. The aerosol laser radar monitor showed that the air quality was mainly sourced from local pollution in the Spring Festival.
