摘　　要：文章根据楚雄市空气污染数据,采用统计的方法从不同的角度探求中小城市空气污染指标的变化规律,并求出三种污染物的同时置信区间及它们之间的关联性。结果表明:楚雄市的空气污染主要由SO2造成,室外空气质量能达到一类地区的水平,三种污染物之间两两相关性较弱,但整体相关性较强,同时根据结论提出了相应的建议。According to the air pollution data in Chuxiong City, this study uses statistical methods to explore changes of Chux-long air pollution indexes from different angles and obtain some results about simultaneous confidence interval of air pollution indexes and their correlation. The results show that the air pollution in Chuxiong City is mainly caused by SO2. The outdoor air qualitycan reach level 1. There are weak correlations between the three kinds of pollutants, but the whole correlation is strong. Corresponding suggestions were put forward according to the conclusion.
