摘　　要：收集并整理了张家口地区1999-2013年的风力数据以及2005-2013年的风电装机数据,依据数据绘制出风速变化图.文中利用SAS软件,进行了年风速与年装机台数、装机容量、新增装机容量之间的相关性分析,结果显示它们之间不具备显著的相关性;进一步分析了风速与年装机台数、装机容量、新增装机容量的平方之间的相关性,并给出线性回归方程,结果表明具有显著相关性.分析表明,装机容量的增加不仅没有减少张家口地区的风速,而是逐年有递增趋势.The wind data of 1999-2013 and the wind turbine data of 2005-2013 in Zhangjiakou area are collected and collated in this paper. According to the data,the figure of wind speed variation was drawn. Using Statistics Analysis System（SAS）, a correlation analysis was made on annual wind speed and annual installed units, installed capacity and the additional installed capacity. The re- sults show that they do not have significant correlation. But further analysis was made on annual wind speed and the square of annual installed units,installed capacity and the additional installed capacity,and the linear regression equation is written out. The results show there was significant correlation. According to the analysis, the increases of the installed capacity do not reduce the wind speed of Zhangjiakou area, but has an increasing trend year by year.
