利用南宁市环境保护监测站2010年11月5日至12（污染个案期）在南宁市区振宁花园、市监测点、区农职院、大自然花园4个有代表性的国控环境空气监测点观测到的空气质量数据，分析颗粒污染物PM2.5和PM2.5的浓度变化及PM2．5的主要化学组分浓度，再利用广西气象服务中心观测的天气数据分析污染个案期的气象条件。结果表明：此次长时间空气污染重，南宁市大气中的颗粒物出现显著升高，颗粒物为此次诱发长时间空气污染物的首要污染因子，颗粒物中的组分以有机质OM和硫酸盐为主；观测时段内气象因素对空气污染存在重要影响，来自湖南方向的污染气团对南宁市的长时间轻微污染也存在一定影响。

Through observing the air quality in four city monitor station of Nanning from 5th to 12th November,2012,the concentration change of particulate pollutant,PM10 and PM2.5, and the concentration of main composition of PM2.5 were analyzed. The meteorological condition during air pollution was analyzed based on meteorological data from Guangxi Meteorological Service Center. The results showed that during the air pollution period, the concentration particulate pollutant as the major cause of the air pollution, increased significantly. OM and Sulfate are the main components of PM2.5 at that time. The meteorological factors play an important role in the air pollution. Air came from Hunan direction also played a certain role in long time air pollution.
