中文摘要: 利用惩罚最大F检验(PMFT)方法并结合详尽的台站历史沿革信息对我国701个气象观测台站年平均风速资料进行了均一性检验，结果表明该检验方法能够应用于对年平均风速资料进行均一性检验，我国年平均风速资料的不连续点主要集中在1～2个，已检验的701个台站中有61.3%的台站年平均风速序列是均一的，表明我国大部分台站风速资料均一性情况良好。仪器变化和台站迁移是引起年平均风速序列非均一性的主要原因，而仪器变化中的仪器换型是造成年平均风速序列非均一性的最重要原因。

Abstract:The annual mean wind speed data of 701 meteorological observation stations have been detected by using Penalized Maximal F Test （PMFT） and the detailed metadata archive. The results show that the homogeneity detection method works well for the annual mean wind speed data over China. The number of change points of the annual mean wind speed may be one or two. The annual mean wind speed series of 61.3 percent are homogeneous among the detected 701 stations, showing that the homogeneity of the annual mean wind speed is good in most areas of China. The changes of instrument and location are the two main causes for the non homogeneity, and the changes in the type of the observation instrument are the most important causes for the non homogeneity of the annual mean wind speed over China.
