利用成都市城区2010年环境监测资料及同期气象资料,分析了成都市城区空气污染物的变化特征,及各污染物浓度与气象条件的关系. 结果表明:1)成都市大气环境中PM10为首要污染物,城区空气质量具有明显的季节特征,最优在夏季,冬季最差;2)成都市大气稳定度稳定类频率的变化幅度与污染物月均值变化幅度较为一致;3)成都市城区污染物除本地污染源外,还受到外地源的影响.

The characteristics of pollution were analyzed by using environmental monitoring and me-teorological data of Chengdu in 2010 . The conclusions are as follows:1 ) The key air pollutants are PM10 ,and the air quality of Chengdu urban has obvious seasonal characteristics,best in summer,in winter the worst;2 ) Chengdu stable atmospheric stability class changes in the magnitude and frequen-cy of the average monthly change in the magnitude of pollutants is more consistent;3 ) In addition to local sources of pollutants in Chengdu city,but also influenced by foreign sources.
