摘　　要：对2014年大连星海三站点位污染物浓度和污染日特征进行了分析。结果表明:星海三站点位采暖期颗粒物和二氧化硫污染较重,主要是受冬季采暖和区域性污染影响;臭氧在非采暖期尤其是7月污染较重,主要是太阳辐射加剧了光化学反应,使臭氧的转化率增高;二氧化氮浓度居高不下,主要受持续性工业污染及机动车尾气排放的影响。Analyzed the pollutants＇ concentration and the air quality pollution days＇ features of Xinghaisanzhan site in Dalian for 2014. It was concluded that, the higher pollution of particulate matter and sulfur dioxide in heating period was mainly affected by the heating in winter and regional pollution; the higher pollution of ozone in non-heating period, especially in July, revealed that solar radiation promoted the photochemical reaction and increased the conversion rate of ozone; the high concentration of Nitrogen dioxide, was mainly affected by the sostenuto industrial pollution and motor vehicle exhaust.
