| 中文摘要: |
| 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。 |

| 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. |
