摘　　要：基于O 3浓度监测数据,采用空间自相关分析和地理探测器,分析了东北地区35个城市2015—2018年O 3浓度的时空变化特征及其影响因素。结果表明,2015—2018年东北地区O 3浓度年际变化呈缓慢上升趋势,季均浓度值呈春夏高、秋冬低的特征,月均浓度变化规律呈倒“V”型分布;受气温影响,O 3浓度高值区主要分布在辽宁及吉林两省,并表现出逐年向北扩增的趋势;O 3浓度具有明显的集聚特征,热点主要分布在辽宁省;气象因素和社会经济因素都是影响O 3浓度分布的重要驱动因子,其中气温、二产占比和民用汽车拥有量与O 3浓度的分布具有极显著相关性。Based on the ozone monitoring date,the spatio-temporal variation of ozone concentration and its influencing factors of 35 cities in Northeast China from 2015 to 2018 were analyzed via spatial auto-correlation analysis and geographical detector.The results show that the interannual variation of ozone concentration increased from 2015 to 2018 and the monthly ozone concentration followed a pattern of inverted"V",which was higher in spring and summer and lower in autumn and winter.The high ozone concentration areas were mainly distributed in Liaoning Province and Jilin Province,which expanded to the north due to the effect of temperature.The ozone concentration had significant characteristics of agglomeration with hot spots distributed mainly in Liaoning Province.Meteorological factors and socio-economic factors all had significant effects on the distribution of ozone concentration.Temperature,the proportion of secondary industry and the ownership of civilian automobiles were all significantly correlated with ozone concentration.
