This research describes and interprets spatial variation in near-surface wind speed around a large scale wind generation operation in a desert steppe environment of Inner Mongolia. Wind speeds were measured at five different heights and distances in front of and behind turbines and compared to that measured simultaneously from reference points immediately outside of the wind farm. The results showed that wind turbines clearly influence the spatial distribution of near-surface wind speed. Relative to reference points, near-surface wind velocity profiles measured at various distances from wind turbines followed a logarithmic distribution. The correlation coefficients for all points were above 0.95 except for a coefficient of 0.8278 corresponding to wind speeds measured 20 m in front of turbines. The wind speed increment rate at 20, 100, and 300 m in front of and behind turbines demonstrated the varying influence of turbines at different points. The area 100 m behind the turbine experienced maximum wind speeds at all height levels observed in the measurement area. The overall wind speed at 300 m distance was relatively low and variation nearest to the turbine was the most complex.

这项研究描述和解释了内蒙古沙漠草原环境下大规模风力发电作业附近近地表风速的空间变化。在风轮机前后的五个不同高度和距离处测量风速，并将其与同时从风电场外部的参考点同时测量的风速进行比较。结果表明，风力涡轮机明显影响近地表风速的空间分布。相对于参考点，在距风力涡轮机不同距离处测得的近地表风速分布遵循对数分布。除与涡轮机前20 m处测得的风速相对应的系数0.8278外，所有点的相关系数均高于0.95。风速增加率分别为20、100，涡轮机前后300 m处显示了涡轮机在不同点的变化影响。涡轮机后面100 m的区域在测量区域中观察到的所有高度水平都经历了最大风速。300 m距离处的总风速相对较低，最接近涡轮的变化最为复杂。
