以半方差函数和克里格插值为基础,利用GS+与Surfer软件对某地区的风能发电时间进行了空间变异性研究,并绘制了空间分布图。结果表明:风能发电时间样本数据符合正态分布规律,可以用克里格方法进行插值分析;研究区年风能发电时间均值为1912.8 h,属于风能可利用区;样本变异系数为0.098,属于弱变异强度,表明风能发电时间的空间分布较为均匀。研究结果为区域风能资源的开发与利用提供了重要参考。

Based on the semi-variance function and the Kriging interpolation , the spatial variability of the annual wind energy available time for a certain area is studied with the software GS +and Surfer .Spatial distribution maps are also obtained .Results show that the sample data of the wind energy available time follows the normal distribution , thus the Kriging method can be used for data interpolation .In the studied area , the annual wind energy available time is 1 912.8 h, which means that the area is a wind energy utilizable region .While the coefficient of variation is 0.098, in-dicating that the spatial distribution of wind energy available time is quite uniform .These results provide an important reference for the development and utilization of the regional wind energy resources .
