中文摘要 利用环境空气质量监测站和国家基准地面气候站数据，研究了2017年河南省臭氧（O₃）污染时空特征及其与颗粒物、前体物和气象因子关系.结果表明，河南省2017年O₃日最大8 h滑动平均值（MDA8）呈现夏季 > 春季 > 秋季 > 冬季的特征，年均值为108 μg·m^-3；各地市均有不同程度O₃超标情况，其中，安阳超标天数高达88 d，信阳最少为17 d；春末夏初（5月和6月）O₃污染最为严重，O₃ MDA8月均浓度在140 μg·m^-3以上，并在6月达到峰值；定性和定量分析显示O₃ MDA8月均浓度与颗粒物，O₃小时浓度与CO、NO₂呈负相关；不同季节、不同城市O₃ MDA8与气象因子（日照时长、气温、降雨、能见度、相对湿度及风速）的相关性具有差异. 英文摘要 The spatio-temporal characteristics of ozone (O₃) pollution in the Henan Province in 2017 and its relationship with particulate matter, precursors, and meteorological factors were studied using the data obtained from the air quality monitoring station and national baseline ground climate station. Results showed that the annual mean O₃ concentration of a maximum daily 8-h average (MDA8) was 108 μg·m^-3 in the Henan Province with the trend of summer > spring > autumn > winter. Different levels of O₃ were observed in various cities. The number of days exceeding the standard was up to 88 days in Anyang, while the lowest was found in Xinyang with 17 days. The most severe of O₃ pollution occurred during late spring and early summer. During this period, the average monthly concentration of O₃ MDA8 was above 140 μg·m^-3, and peaked in June. The qualitative and quantitative analysis showed that the monthly average concentration of O₃ MDA8 was negatively correlated with particulate matter, and the O₃ hourly concentration was also negatively correlated with CO and NO₂. The O₃ MDA8 concentration and meteorological factors (sunshine duration, temperature, rainfall, visibility, humidity, and wind speed) had different correlations during different seasons and various cities.
