摘要
本文采用大连市10个国控子站2013年全年臭氧自动监测数据进行分析,总结臭氧浓度的月变化规律。分析结果表明:大连市区环境空气中臭氧主要来自于光化学反应,其浓度变化受太阳辐射的影响,其月浓度值在5月份达到峰值;此外,大气对流、近地面环境及污染源排放等因素也会对大连市区近地面大气中的臭氧浓度造成影响,导致大连特殊地区的臭氧浓度值在不同月份达到年内的峰值。
The monthly changed pattern of ozone concentration was summed up by analysis of air automatic monitoring data in Dalian. It showed that ozone was generated mainly by photochemical reaction in Dalian, the ozone concentration, which reached a peak in May,was mainly affected by solar radiation; The ozone concentration was also affected by atmospheric convection atmospheric convection atmospheric convection atmospheric convectionatmospheric convection, environment,pollution emissions and other factors,which caused other ozone concentration peaks in different months in Dalian special area.
