摘　　要：利用OMI采集的中国区域大气臭氧时空分布变化的臭氧总量数据(2018~2019年),研究了中国地区大气臭氧时空变化趋势及其影响因素。结果表明:近两年中国地区臭氧总量呈周期性变化,总体柱浓度呈下降趋势;春季臭氧柱浓度最高,秋季最低;臭氧柱浓度的空间分布呈现明显的北高南低的纬度分布特征。经分析,臭氧的时空差异变化可能受大气环流、季节变化以及人类活动等诸多因素影响,该研究结果有利于从宏观上评估全国乃至全球臭氧污染特征变化的差异,从而对有针对性地开展环境污染防控具有重要意义。The spatial and temporal variation of atmospheric ozone in China(2018-2019)was collected by OMI to study the spatial and temporal variation trend of atmospheric ozone in its influencing factors and China.The results show that the total amount of ozone in China changes periodically in the past two years,and the total column concentration decreases.The ozone column concentration is the highest in spring and the lowest in autumn.The spatial distribution of ozone column concentration has the characteristics of high latitude in north and low latitude in south.According to the analysis,the spatial and temporal variation of ozone may be affected by atmospheric circulation,seasonal changes,human activities and other factors.The results of this study are conducive to the macroscopic assessment of the differences in characteristics of national and global ozone pollution,so as to carry out targeted prevention and control of environmental pollution with great significance.
