摘要
以安庆市2007～2013年空气污染日值资料为基础，分析了3种大气污染物（ PM10、SO2、NO2）不同时间尺度的变化特征，并结合安庆市地面气象日观测资料，研究了污染物浓度与气象因子的变化关系。结果表明：2007～2013年，安庆市首要大气污染物为PM10，3种主要大气污染物的载荷顺序为PM10（82．77μg／m3）＞SO2（47．61μg／m3）＞NO2（33．95μg／m3）；冬季和春季大气污染物浓度较高，夏季最低；相关分析表明风、降水、气温和湿度等是与安庆大气污染物浓度呈显著线性相关的气象因子。
Based on the monitoring data of atmospheric pollution （ daily average concentration of PM10 , SO2 and NO2 ） in An-qing city during 2007~2013, we analyzed the change characteristics of these atmospheric pollutants in different time scales.Combi-ning with the daily observation data of ground meterological factors in Anqing city, the author studied the relationship between pollu-tant concentration and meterological factors.The results indicated that：from 2007 to 2013, the chief atmospheric pollutant in An-qing city was PM10, and the concentration of 3 main atmospheric pollutants revealed the order of PM10 （82.77 μg/m3） ＆gt;SO2 （47.61 μg/m3）＆gt;NO2（33.95 μg/m3）.The concentration of atmospheric pollutant was higher in winter and spring, and was the lowest in summer.The results of correlation analysis showed that the concentration of atmospheric pollutant in Anqing city was sig-nificantly linearly correlated with the following meterological factors：wind, rainfall, air temperature and humidity.
