| 中文摘要: |
| 利用2012—2015年泰州市空气质量监测数据，分析夏、秋收期间城市环境空气质量特征，探讨引发重污染天气的原因。结果表明，夏收期间空气质量整体优于秋收，2012年、2013年秋收期间空气质量最差，达到重污染以上的天数分别为10 d、6 d，颗粒物尤其是PM2.5超标较严重，2015年秋收期间空气质量显著好转。秸秆焚烧日PM2.5和PM10质量浓度呈较高相关性，PM2.5/PM10值比非秸秆焚烧日高。基于气团后向轨迹及秸秆焚烧卫星遥感监测火点图将污染事件分类，研究得出秸秆焚烧和区域输送是导致城市污染加重的主要因素。 |

| The study analysed the characteristic of air quality in Taizhou during the period of the summer harvest and the autumn harvest based on air quality automatic monitoring data from 2012 to 2015, and the causes of air pollution was discussed. The results showed that the air quality was better in the summer harvest than that in the autumn harvest. The air quality in the autumn harvest of 2012 and 2013 were the worst, and heavy pollution days were 10 d and 6 d, respectively. The concentration of particulate matter, especially PM2.5, far exceeded the limit. Compared with the previous years, the air quality improved significantly during the autumn harvest in 2015. The concentration of PM2.5 and PM10 during the straw buring days were highly correlated, and the ratio of PM2.5/PM10 was higher in non straw burning days. Air pollution incidents were classified based on air mass backward trajectory and straw burning point diagram by satellite remote sensing monitoring. Results showed that heavy air pollution in city was mainly caused by waste straw burning and pollutant regional transport. |
