Abstract
Using the observational data of daily average mass concentration of main air pollutants (SO2, NO2 and PM10) during 2006～2015 provided by Xi'an Environmental Monitoring Station, the author analyzed the change rule of concentration of these air pollutants in different time scales.According to the observational data of surface meteorological factors and upper inversion intensity in Xi'an, we studied the relationships between mass concentration of SO2, NO2 and PM10 and meteorological condition in Xi'an.From 2006 to 2015 in Xi'an, the annual average mass concentrations of SO2 showed a slow downward trend;while that of NO2 and PM10 revealed a slow rising trend.The seasonal variations in mass concentration of 3 kinds of air pollutants in Xi′an all appeared as summer< autumn (spring)< winter.The mass concentration of SO2, NO2 and PM10 was obviously negatively correlated with wind speed and air temperature, and was positively correlated with inversion intensity.Precipitation could eliminate or weaken these main air pollutants.关键词
