摘要
以2013年沈阳市11个空气质量自动监测站的大气臭氧自动连续监测数据为基础,对臭氧浓度的区域分布、季节变化、日变化特征进行分析。结果表明:O_3浓度在午后15∶00左右出现峰值,O_3浓度最高的月份为4—9月,中心城区O_3浓度低于外围。在此基础上提出了沈阳市低空大气臭氧污染防治办法。
Continuous monitoring in 11 ozone monitoring stations was conducted during January to December 2013 in Shenyang. The data was applied to analyze the spatial distribution, seasonal change, and daily change of ozone. The results showed that the peak O3 concentrations in Shenyang often appeared at about 3 pm. However, its con- centrations varied in twelve months. The highest concentrations appeared in the central urban area in April to Sep- tember. Above all, pollution prevention approaches were put forward.
