东北沿海城市与其他地区臭氧污染异同分析

A Brief Analysis of the Similarities and Differences of Ozone Pollution in Northeast Coastal Cities and Other Areas

根据2019年空气自动站监测数据,对比分析了东北沿海城市与我国其他污染防控重点区域的臭氧污染特征,并在文献调研的基础上,阐述了东北沿海城市与内陆城市以及其他沿海城市臭氧浓度变化规律。结果表明:东北沿海城市受光照时长影响,臭氧小时浓度峰值出现时段较晚;在海陆风影响下,夜间可能也出现一次峰值。虽然臭氧年均值达标,但臭氧污染日占比较大,东北沿海城市的臭氧污染问题应引起足够重视。

Based on the monitoring data of automatic air stations in 2019,this paper analyzed the characteristics of ozone pollution in the northeast coastal cities and other key areas of pollution control.On the basis of literature research,this paper described the variation rules of ozone concentration in the northeast coastal cities,inland cities and other coastal cities.The results showed that the peak of hourly ozone concentration appeared later in the northeastern coastal cities due to the influence of light duration,and it may also appear a peak at night under the influence of land and sea breeze.Although the annual mean value of ozone reaches the standard,the proportion of ozone pollution day is relatively large,and the problem of ozone pollution in the coastal cities of northeast China should be paid enough attention.
