摘要针对青岛“上合峰会”保障期间出现夜间臭氧（O₃）浓度增长的现象，本文利用地面常规观测资料和污染物浓度数据对其进行分析和研究.结果表明，在6日20：00~23：00，青岛出现O₃浓度持续性增长，峰值浓度达194μg/m³，浓度增长速率达10.7μg/（m³·h）.结合NCEP/FNL再分析资料可知，在夜间西南风的作用下，江苏、安徽等地排放的O₃及其前体物向青岛传输，并在边界层内下沉运动作用下，将其传输至近地面.通过计算边界层内通风量可知，6日边界层内最大风速区高度逐渐降低，达到低空急流的标准，且在夜间1000m以下的通风量呈现出波动性增长，500m和500~1000m高度的通风量峰值分别为3900和5892m²/s.另外，本研究基于CAMx空气质量数值模式中的O₃来源追踪方法（OSAT）对其进行了模拟分析，结果显示在夜间O₃增长时段（20：00~23：00），青岛地区的主要贡献来源分别为江苏、安徽以及上海，上述3地的贡献比例平均为62.3%、16.6%和8.6%.

Abstract：To investigate the causes of ozone concentration increasing at night during the Shanghai Cooperation Organization Summit in Qingdao, the ground observation data and pollutant concentration data were used to analyze it in this study. As the results showed that, the ozone concentrations increased continuously with peak concentration of 194μg/m³, and the growth rate of 10.7μg/(m³·h) from 20:00 to 23:00 on the 6^th. By using the NCEP/FNL reanalysis data, it could be known that ozone and its precursors emitted from Jiangsu and Anhui province were transmit to Qingdao under condition of southwest wind at night, and transmitted to the surface under the sinking movement in the boundary layer. By calculating the ventilation index of the boundary layer, height of the maximum wind speed decreased gradually in the boundary layer on the 6^th, which met the standard of low-altitude jets, and the ventilation index increase fluctuation below 1000m at night, of which were 3900 and 5892m²/s at 500m and 500~1000m,respectively. What’s more, the ozone pollution sources in Qingdao were simulated based on the Ozone Source Apportionment Technology (OSAT) in the CAMx air quality model. As the results indicated that the main sources areas were Jiangsu, Anhui province and Shanghai, with average contribution ratio of 62.3%, 16.6% and 8.6%, respectively.
