　　通过对2006～2010年成都市的空气污染指数及其2006～2010年每月降水量进行小波分析，以及对两者不同时间尺度下的小波系数进行滑动比较。得到如下结论：（1）在2006~2010年期间，成都市的空气污染状况以优良为主，冬季的污染较重，夏季较轻，变化周期为3个月，2006年、2008年和2010年波动较大；（2）成都市月降水量的变化周期也是3个月，2006～2008年和2010年其月降水量波动较大；（3）成都市的月平均空气污染指数与月降水量之间呈现负相关关系，其相关系数为-0.498，而两者的波动性呈现出一定的正相关关系。

a wavelet analysis was made about the air pollution index and monthly precipitation in Chengdu from 2006 to 2010, and the wavelet coefficients for different scales were compared. Results show that during 2006~2010, the air quality of Chengdu was excellent for most of time, and the air pollution was serious in Summer and light in Winter, which tent to be high volatile in 2006~2008 and 2010, the period was 3 months;the monthly precipitation of Chengdu was high volatile in 2006, 2008 and 2010, and the period was 3 months as well;the air pollution index and the monthly precipitation of Chengdu present negative correlation, and the correlation was -0.498, while a positive correlation for their volatility.
