摘　　要：利用2013—2016年江苏省国控空气自动站获得的臭氧(O_3)观测数据,探讨江苏省O_3时空变化特征。结果表明,自2013年以来江苏省大气氧化剂OX(O_3和NO2)和O_3浓度呈逐年升高趋势,升高速率分别为0.98×10-9a-1和3.70μg/(m3·a),O_3增幅在我国处于较高水平。在O_3空间分布上,东部沿海O_3浓度相对高于西部内陆,O_3浓度高值由沿海地区逐渐向内陆辐散,呈现出区域性O_3污染。结合经验正交分解进行聚类统计检验,结果显示江苏省O_3分区主要分为苏南、苏中和苏北3类,与江苏省经济发展水平表现出一定的同步性。Ozone concentrations data obtained from automatic air monitoring stations in Jiangsu Province were used to analyse its temporal and spatial distribution characteristics from 2013 to 2016. Results showed that the long-term trend of the OX and O3 had undergone a significant increase in the period of 2013-2016,with an average rate of 0. 98 × 10-9a-1and 3. 70 μg/（ m3·a）,and O3 persisted at a high level in China. Spatial distributions of O3 were substantially agreed during 2013-2016,O3 concentration was lower in western Jiangsu,higher in eastern coastal areas. O3 concentrations would diverge gradually from eastern areas to the west,it showed a regional pollution. Based on EOF analysis and Cluster analysis of Statistic Test,the spatial distribution was divided into three parts： south area,middle area and north area which showed a certain synchronicity with the level of economic development.
