摘　　要：为了对大连市大气中气态总汞的影响因素进行研究,本文采用"超级站"对大连市气态总汞及可能影响因素进行了长达1年(2015年)的连续监测,结果表明:2015年大连市气态总汞年平均值为3.72 ng/m3,高于全球背景值1.5~2.0 ng/m3,但要优于国内北京、长春、重庆、贵阳、桂林、青岛等已报导的一些城市的气态总汞水平;不同的研究时间段,作气态总汞和SO2、NO2、PM10、PM2.5、CO、O3、AQI、UV辐射、太阳总辐射、大气稳定度、光照强度、风速、气温、气压、相对湿度等可能影响因素的相关性分析,发现对气态总汞的主要影响因素均不相同,并分析了可能的原因。In order to study the influence factors of total gaseous mercury in the atmosphere of Dalian city, we used “Super Station” to monitor the total gaseous mercury and possible influence factois in Dalian city for one years （2015）. the results showed that the annual average value was 3.72 ng/m^3, higher than the global background value 1.5-2.0 ng/m3, however lower than the other cities had been re-ported in China. On the different periods of study time, we done coirelation analyses between the total gaseous mercury and SO2,NO2,PM10,PM2.5,CO,O3,AQI,UV radiation, solar radiation, atmospheric stability, light intensity, wind speed, air temperature, air pressure, relative humidity and other possible inJEluence factors, found the main influence factors of the total gaseous mercury were not the same and analyzed the possible reasons.
