| 中文摘要: |
| 目的 了解安徽省臭氧时空分布特征及其与气象要素的关系。方法 利用2017—2019年环境空气质量监测的臭氧数据和气象观测数据，并结合后向轨迹模型和潜在源区分析，分别评价安徽省臭氧污染区域分布和气象要素对臭氧浓度的影响，并分析区域传输对安徽省臭氧浓度的影响。结果 2017—2019年安徽省及各市臭氧浓度增长显著，2019年同比2017年增幅为12.2%，第二季度(4、5、6月)和第三季度(7、8、9月)是O3浓度相对较高的时期，且O3污染有“前移后滞”趋势。污染气团主要来自于安徽省内部地区，潜在源分布显示，皖中地区(合肥、安庆、马鞍山等城市)的贡献比例最大，外地源贡献主要来源于江苏省和山东省等。臭氧浓度与温度和太阳总辐射强度呈正相关，与降水量和相对湿度呈负相关，与风速关联性不大。结论 安徽省臭氧污染逐年增加的主要原因是本地排放的加剧，外源输送可能会产生一定影响，加之高温和强太阳辐射的影响，会加剧臭氧污染的程度，并导致重污染。 |

| In order to explore the temporal and spatial distribution characteristics of ozone and its impact on meteorological factors in Anhui Province, we use the ozone data and meteorological observation data of ambient air quality monitoring from 2017 to 2019, combined with HYSPLIT(Hybrid Single Particle Lagrangian Integrated Trajectory) model and PSCF( Potential Source Area Analysis), respectively evaluates the regional distribution of ozone pollution and the impact of meteorological factors on ozone concentration in Anhui province, and analyze the impact of regional transmission on ozone concentration in Anhui province. The results show that:from 2017 to 2019, the ozone concentration in Anhui province increased significantly, with a year-on-year increase of 12.2%. The second quarter (April, May and June) and the third quarter (July, August and September) are periods with relatively high ozone concentration. The results show that the air pollution mainly comes from the inner part of Anhui province, while the potential source distribution shows that the contribution of air pollution mainly comes from the midland (Hefei, Anqing, Ma’anshan, etc.), and other sources were mainly from Jiangsu and Shandong provinces. Ozone concentration is positively correlated with temperature and total solar radiation intensity, negatively correlated with precipitation and relative humidity, and has little correlation with wind speed.. The results show that the increase of ozone pollution in Anhui province is mainly due to the aggravation of local emissions, and the external transport may have a certain influence. In addition, the impact of high temperature and strong solar radiation will aggravate the degree of ozone pollution and lead to heavy pollution. |
