利用长株潭城市群24个监测点PM_(2.5)小时监测数据,研究2013—2015年春节期间(7 d)和春节前后(14 d) PM_(2.5)污染差异及变化,并分析旅游休假活动对空气质量的影响。在去除气象条件(日降水量大于4 mm)影响后,从PM_(2.5)污染程度差异、PM_(2.5)浓度日变化差异和假日效应的空间差异3个方面分析了PM_(2.5)污染的春节假日效应。结果表明,整体上长株潭地区春节期间PM_(2.5)浓度比春节前后高12 μg·m~(-3),但春节后(7 d) PM_(2.5)浓度比春节期间低41.5%,“节后效应”明显。由于受烟花燃放等假日活动影响,春节期间PM_(2.5)浓度在00: 00—02: 00时段显著上升, 02: 00时PM_(2.5)浓度比非春节期间高47.6%...

PM2.5 has been a major concern of the public due to its obvious effect of reducing visibility and endangering human health. Based on the hourly PM2.5 monitoring data gathered around the clock at 24 monitoring sites in the Chang-Zhu-Tan metropolitan area, analysis was performed of variation of PM2.5 pollution throughout 7 days before spring festival, 7 days of spring festival and 7 days after the festival in 2013, 2014 and 2015 to explore impacts of holiday activities, including tourism, on air quality. After excluding the effect of meteorologic...
