| 摘 要： | 以沈阳2013—2015年臭氧(O_3)监测数据为基础,从地域差异及时间变化上分析了沈阳O_3浓度变化特征。结果表明:沈阳城市外围O_3浓度高于城市中心;O_3浓度变化具有明显季节特征,夏季O_3浓度最高,冬季最低;O_3浓度日变化呈单峰分布,谷值出现在06:00,峰值出现在14:00;O_3浓度出现明显"周末效应",周末白天O_3浓度高于工作日O_3浓度,夜间差异不大。

| Abstract: | Base on the observational data of near surface ozone in Shenyang from 2013 to 2015, the pollution feature of ambient ozone in the aspect of area differences and time variations were analyzed in this paper. The results showed that the ozone concentration in periphery of the city was higher than that of the city center. The local ozone concentration presented a significant seasonal variation, with the highest value in summer and lowest in winter. The daily ozone concentration curve is unimodal, the peak generally appears in the afternoon at 14:00 and the trough at 06:00. Ozone concentration had significant weekend effect, with higher ozone concentration over the weekend at the daytime, and the difference was not significant at night. |
