【摘要】 利用2013年青岛市区的O₃监测数据,系统分析O₃污染状况、生成的敏感性及影响因素。结果表明,2013年青岛市区O₃年评价质量浓度为0.114 mg/m3,日评价质量浓度达标率为99.5%;空间分布显示,商业区和居民区的O₃浓度较工业区高。O₃生成主要受前体物VOCs控制,且高温、低湿、长日照时数等气象条件均有利于O₃的生成。植被排放的VOCs对O₃污染有重要贡献,机动车排放的贡献则不显著,控制其排放反而会引起O₃浓度升高。更多还原

【Abstract】 Based on the O₃ data in 2013,the pollution situation,the formation sensitivity and influencing factors of O₃ in Qingdao were analyzed. The results showed that the annual concentration of O₃ was 0. 114 mg / m3 in 2013,and the standard-reaching rate of O₃ daily concentration was 99. 5%. Spatial distribution illustrated that O₃ concentration in commercial and residential areas was higher than that in industrial areas. Sensitivity analysis showed that urban O₃ in Qingdao was mainly controlled by VOCs precursors. Weather conditions such as high temperature,low humidity and long sunshine hours are conducive to generate O₃. Vegetation emissions have important contributions to O₃ pollution,and vehicle emissions have no significant contributions,on the contrary,controlling vehicle emissions can elevate O₃ concentration.更多还原
