以合肥市董铺雨量站1961-2010年降雨资料为例，利用morlet小波换对其水文序列的多时间的尺度演变特性进行了分析，并预测了董铺水库地区2010年以后的年降雨量变化趋势。结果表明：董铺年降雨时间序列具有多时间尺度变化特性，存在5个周期分别为2a、6a、11a、46a和48a，其中46a和48a分别为第一主周期和第二主周期；2010年后的未来几年内董铺水库地区降雨量将处于偏丰期。

Taking the process of 50 years annual rainfall from 1961-2010 of Dongpu Rainfall Station for example,this paper analyzed the muliple time scales variation characteristics of hydrological series based on Morlet wavelat transform and forecasted the trend of annual rainfall of the Dongpu Reservoir since 2010.The result show that the Dongpu Reservoir has five main periods of rainfall,which are 2-year,6-year,11-year,46-year and 48-year.And,the first and second main periods of rainfall are 46-year and 48-year respestively.In the next a few years since 2006,the rainfall of Dongpu Reservoir will be high flow period.
