| 分析了我国典型南方城市的臭氧污染特征，选取我国4个有代表性的南方重点城市武汉、宁波、中山和南宁的2013-2015年监测数据，使用EXCEL、ORIGIN和MATLAB等统计软件开展研究，结果表明：我国南方典型城市的臭氧质量浓度分布有明显时间变化特征，超标时间跨度大，部分南方城市与氮氧化物存在较明显负相关性，相关系数高于-0.6；受城市所在不同地理位置、气象因素、大气扩散条件及可能的不同本地排放污染源构成等因素影响，4个城市的近3年臭氧浓度月均值、超标情况和年内峰值均存在一定差异和分组相似性；与部分气象因素也表现出显著相关性。 |

| This paper intend to explore the characteristics of ozone pollution in typical southern cities of China, including temporal and spatial variation, influencing factors, ozone exceed status and regulatory rules of concentration variation. 4 representative cities from southern China were selected, which are Wuhan, Ningbo, Zhongshan and Nanning, the monitoring data from 2013 to 2015 was used to carry out research on the use of EXCEL, ORIGIN and MATLAB statistical software. The results showed that the ozone concentrations distribution of study cities have obvious time variation, pollution covers a long time span, and some southern cities' ozone have obvious negative correlation with NO2, the correlation coefficient is higher than -0.6; due to the 4 cities have different geographical location, weather, local emission source of pollution and other factors, in the past 3 years, there were some differences and similarities in the monthly concentration, the exceeding standard and the annual maximum month; and some meteorological factors also showed significant correlation. |
