摘　　要：为分析大气环境质量变化趋势,为广州市大气环境质量改善提供理论依据,首先采用传统的空气污染负荷方法对演变特征进行了分析,在此基础上又利用因子分析方法对广州市大气环境质量的主控因素进行提取解译。在得到4个大气环境控制公因子的基础上,分析了广州市大气环境演变规律。结果表明,广州市大气环境质量与广州市的经济发展是密切相关的。从2001年开始广州市大气污染程度呈现出先升高后降低的趋势,以2005年为拐点大气环境质量逐渐好转;广州市的大气污染已转变成复合型大气污染。In order to analyse the changing trends of atmospheric environmental quality thus providing a theory basis for the improvement of air quality in Guangzhou, the traditional air pollution load method was firstly used to analyze the evolution characteristic. Factor analytic method was then used to find out the main controlling factors of air quality in Guangzhou. On the basis of the above, atmospheric evolution in Guangzhou was analysed. The result showed that air pollution firstly increased and then decreased during the year 2001 to 2010. As a turning point, air quality was improved in 2005, which was closely related to the development of economy of Guangzhou. Air pollution in Guangzhou has turned into a complex atmospheric pollution.
