摘　　要：利用2005—2018年周口市OMI数据,对臭氧总量时空变化特征进行了分析研究。首先,分析了周口市臭氧总量的年平均值空间分布特征,各年份臭氧年平均值基本呈纬向分布趋势,即周口市北部臭氧总量高、南部臭氧总量低;其次,对周口市臭氧总量的差值空间分布特征进行了分析,2005—2018年周口市中部地区的臭氧变化比较大;同时,对周口市臭氧总量年平均值的纬向变化特征行了分析,在小区域范围内,周口市的臭氧变化不符合纬向变化特征,随着纬度的增加臭氧总量整体变化不大。This paper used the OMI data of Zhoukou City from 2005 to 2018 to study and analyzed the spatiotemporal variation characteristics of total ozone amount.Firstly,the spatial distribution characteristics of the annual average of total ozone in Zhoukou City were analyzed.The analysis results indicated that the annual average ozone values of each year showed a zonal distribution trend,with a higher total ozone amount in the northern part of Zhoukou City and a lower total ozone amount in the southern part.Secondly,the spatial distribution characteristics of the difference of total ozone in Zhoukou City were analyzed.The analysis results showed that the ozone in the central area of Zhoukou City changed greatly from 2005 to 2018.At the same time,the latitudinal variation characteristics of the annual average of total ozone in Zhoukou City were also analyzed.The analysis results showed that the ozone variation in Zhoukou City did not accord with the latitudinal variation characteristics in a small area,and the total ozone changed little with the increase of latitude.
