【摘要】 根据广东省21个地级以上城市的102个国控空气质量监测站点监测结果,分析农历年春节期间（法定假期除夕～正月初六共7天）燃放烟花爆竹对广东省PM_2.5浓度的影响。2018年农历年春节期间监测结果表明,烟花爆竹的集中燃放会在短时间内造成城市PM_2.5浓度瞬间上升,并在初一凌晨达到峰值,导致正月初一当天城市空气质量超标,全省空气质量显著变差。分析对比近2年监测结果可以得出结论,春节期间PM_2.5浓度峰值均出现在非珠三角地区城市,非珠三角区域浓度显著高于珠三角区域。更多还原

【Abstract】 According to the monitoring results of 102 state-controlled air quality monitoring stations in 21 cities in Guangdong Province, the paper analyzed the influence of burning fireworks on PM_2.5 concentration in Guangdong during Spring Festival（legal holiday from New Year’s Eve to the first six days of the Chinese Lunar Year, totally 7 days at the beginning of the month）. Monitoring results during the Spring Festival in 2018 showed that burning fireworks would cause PM_2.5concentration to increase instantly in a short time, and reach the peak in the early morning on Chinese New Year’s day. It caused that air quality exceeded the standard. The air quality in the whole province was significantly worse. Analysis and comparison of monitoring results in the last 2 years can draw conclusions that, during the Spring Festival, the peak of PM_2.5 concentration appeared in non-Pearl –River-Delta cities. The concentration of the Pearl River Delta region is significantly higher than that of the Pearl River Delta region.更多还原
