利用商都化德风区内气象观测站1959-2011年的风速观测资料，采用线性倾向估计法、Mann-Kendall法、墨西哥帽状小波分析方法，研究了该风区内平均风速的气候变化特征。结果表明：该风区逐年平均风速春季最大，夏季最小；53a来平均风速整体呈下降趋势，变化率约为-0．036m/（s· a）。年平均风速在80年代末出现了从高到低的突变。1986年到2000年之间风速序列均显著存在着8-10年的周期振荡。

Based on the wind observation from Shangdu and Huade county of Inner Mongolia and linear tendency estimate method , Mann-Kendall method and Morlet wavelet , this paper examines the temporal climate change characteristics of the near -surface average wind speed in this county .The results indicate the annual mean wind speed is higher in spring , weaker in summer .The annual average wind speed is on a decreasing trend for 53a.The rate of change is -0.036 m/(s· a).The annual average wind speed appeared the turning point from high to low in the late 80 s.The wind speed sequence shows the periodic oscillation of 8-10 years significantly from 1986 to 2000 .
