中文摘要：
采用一维Morlet复值小波变换对毛乌素沙地腹地1960-2009年气候变化的时间尺度特征进行了分析,结果表明：50年来,毛乌素沙地腹地年平均气温上升的气候变化倾向率为0.25℃/10a,年降水量下降的倾向率大小为11.383mm/10a;年平均气温存在着28a、13a和6a,年降水存在9a、28a、7a、5a和14a的多重时间尺度上的复杂嵌套结构,气温变化以28a尺度的周期振荡最强,降水变化以9a尺度的周期振荡最强。
英文摘要：
The time scale features of climatic changes of Mu Us Sandland hinterland from 1960 to 2009 were analyzed using the one-dimension Morlet complex wavelet transform.The results showed that the increasing tendency rate of annual mean air temperature and the descendant tendency rate of annual precipitation were 0.25℃/10a and 11.383mm/10a in recent 50 years,respectively.There were the complex nested structures existed in multiple time-scale that air temperature with periodic oscillation of 28a,13a,6a and precipitation periodic oscillation of 9a,28a,7a,5a,14a,whereas 28a and 9a periods of oscillation were the strongest in temperature and precipitation.
