泰山顶与济南市大气臭氧浓度变化规律研究

利用2003年7月至9月在泰山顶和济南市3个月的臭氧（O3）自动连续监测数据，对两地O3浓度的频率分布、日变化和日际变化等特征进行对照分析。实验结果表明，泰山顶O3小时平均浓度频率分布比较集中，济南市O3小时平均浓度频率分布比较分散。泰山顶各月O3小时平均浓度的平均值和日均值均高于济南市；泰山顶O3小时平均浓度的最大值低于济南市，而O3小时平均浓度的最小值要高于济南市。泰山顶O3小时平均浓度日变化规律与济南市O3小时平均浓度日变化规律有很大差别，泰山顶O3小时平均浓度日变化很平缓，最大值与最小值相差不大，济南市O3小时平均浓度一般在中午和午后浓度较高，早晨和夜晚较低。

Ozone concentration and its frequency distribution for the top of Mountain Tai and City of Jinan

The frequency distribution, diurnal variation and daily variation of ozone concentration for the top of Mountain Tai and City of Jinan were evaluated and compared, using the ozone data of continuous monitoring from July to September 2003. The frequency distribution of 03 concentration on the top of Mountain Tai was centralized, while it was dispersed in Jinan. The monthly average concentration and the daily average concentrations on the top of Mountain Tai were higher than those in Jinan; the maximum O3 concentration on the top of Mountain Tai was lower than that in Jinan, while the minimum O3 concentration on the top of Mountain Tai was higher than in Jinan. The diurnal variations were also different; ozone concentration on the top of Mountain Tai was more constant through out the day, while it was higher in the afternoon, reaching the daily maximum at 2 Pm, and lower in the morning and evening in Jinan.
