摘　　要：文章利用2009年全国31个主要城市年平均空气质量数据,运用主成分法评价各城市空气质量,得到海口、拉萨、南宁空气质量最好,乌鲁木齐最差;运用因子分析法影响各城市空气质量的主要污染源得出北方城市以燃煤排放为主,南方城市以汽车尾气排放为主;运用Bayes判别法得到深圳2009年空气质量为二级。The paper use the annual average air quality index data of 31 major cities of China in 2009. Using statistical analysis methods of principal component analysis to evaluate the air quality levels .Haikou, Lhasa, Nanning is the best, Urumqi is the worst. By using factor analysis we find the nortbern city is mainly impact by coal-based pollution, the southern city is mainly impact by car emissions. Using Bayesian discriminant method get air quality as secondary in 2009 of Shenzhen.
