摘　　要：基于臭氧日最大8小时平均浓度,利用描述性统计、单因素方差分析等数理统计方法,分析乌鲁木齐市2014—2023年臭氧浓度时间变化特征。结果表明:2014—2023年,乌鲁木齐市臭氧年均值浓度呈上升趋势,臭氧为首要污染物天数呈上升趋势。臭氧月均值浓度变化呈倒“V”型,最大浓度主要出现在7月;臭氧季均值浓度呈夏季最高,冬季最低的趋势;采暖期和非采暖期臭氧年均值浓度均呈上升趋势,非采暖期臭氧均值浓度大于采暖期。研究结果可为乌鲁木齐市大气污染防治工作提供前期理论数据。Based on the daily maximum 8-hour average ozone concentration,descriptive statistics and one-way ANOVA analysis were used to analyse the temporal distribution variation characteristics of ozone concentration in Urumqi from 2014 to 2023.The results indicate that from 2014 to 2023,the annual average ozone concentration and the number of days with ozone as the primary pollutant in Urumqi showed an increased trend.The monthly average variation of ozone concentration followed a patten of inverted“V”,and the highest ozone concentration mainly appeared in July.The seasonal average variation of ozone concentration showed a trend of the largest in summer,and the lowest in winter.The average ozone concentration in heating period and non-heating period showed an increased trend in Urumqi,and the average ozone concentration in non-heating period was higher than that in heating period.The research results can provide preliminary theoretical data for the prevention and control of air pollution in Urumqi.
