摘　　要：利用2019年辽宁省环境空气质量监测数据及气象观测数据,分析辽宁省臭氧污染特征及臭氧浓度变化的主要影响因素。结果表明:2019年辽宁省营口市臭氧污染相对最重,各城市臭氧浓度表现为春夏交替季污染较重,在5月达到臭氧浓度峰值;沈阳、鞍山、营口、铁岭等中部城市臭氧浓度处于高压后低压前、低压带底及低压前等天气系统控制时,臭氧浓度相对较高;各城市臭氧浓度受气温、风速、风向及相对湿度等因素共同影响,与气温、风速呈正相关,与相对湿度呈负相关,且与气温相关性最高。Based on the ambient air quality monitoring data and meteorological data in Liaoning Province in 2019,this paper analyzed the characteristics of ozone pollution in Liaoning Province and the main influencing factors of ozone concentration changes.The results showed that the ozone pollution in Yingkou City was relatively the heaviest in 2019,the ozone concentration in each city shows that the pollution is heavier in the alternate seasons of spring and summer,reaching peak ozone levels in June;When the ozone concentration in central cities such as Shenyang,Anshan,Yingkou,and Tieling is under the weather of after high pressure and before low pressure,at the bottom of low pressure belt and before low pressure,the ozone concentration is relatively high.Ozone concentration affected by factors such as weather,air temperature,wind speed,wind direction and relative humidity,is positively correlated with temperature and wind speed,and negatively correlated with relative humidity,and has the highest correlation with temperature.
