| 摘要: |
| 利用南京市空气质量监测结果，对2013年8月及亚青会期间空气质量状况进行评价与分析，并结合采取的临时管控措施及气象条件状况，分析空气质量变化的相关原因。结果表明，8月份南京市空气质量均达到良的等级，亚青会期间空气质量进一步改善，多项污染物浓度达到一级标准，且同比上年明显下降，这一方面与针对工业点源、机动车流动源及扬尘面源采取了临时管控措施，一定程度降低污染排放有关；另一方面与亚青会期间的气象条件有利于污染物扩散有关。 |

| Abstract: |
| Based on Nanjing air quality monitoring results during the Asian Youth Games (AYG) in August, the air quality was evaluated and analyzed and the relevant reasons of air quality change were discussed with the temporary control measures and the meteorological conditions. The results showed that the air quality in Nanjing in August achieved a moderate level and was further improved during the AYG. According the Air Quality Standards of different pollutants, many of them reached moderate levels and the pollution decreased obviously compared with the same period of the last year. This could be attributable to steps taken to reduce emissions from industrial point sources as well as temporary control measures on motor vehicle flow and dust of non point sources. Additionally, general meteorological conditions during the period of the games were beneficial to the diffusion of pollutants. |
