摘要
对2013—2016年重庆主城地区17个监测点位的臭氧小时数据进行了统计分析,结果显示:缙云山等点位具有臭氧小时浓度高、污染反应持续时间长的特点;解放碑、礼嘉等点位具有臭氧污染"晚、频、快"的时间特征;各测点在O_3超标日大体呈现"城市周边先,城市中心后"的污染空间规律。
The hourly ozone statistical data of the 17 monitoring points in Chongqing urban area during 2013-2016 showed that Jinyun Mountain and other sites had high hourly ozone concentration and long duration of pollution response. The time characteristic in Monument for Liberation,Lijia,and other sites were late,frequent,and fast.The spatial law of each monitoring point in the ozone generally presented the phenomena of firstlyoccurring around the city,then spreading to the city center.
