最后，将编程计算结果进行统计处理，得到各区段的自然风风速频率分布以及风速极值。

Finally, natural wind speed frequency distribution and the extreme wind speed in each section have been got by statistically processing of the routine calculation results.

风的扰动主要包括风速、频率等的变化，并受不同林木密度和复杂地形下的风场分布的影响。

The disturbance of wind mainly means the variety of speed and frequency of wind, and it's affected by forest density and the distribution of wind field under complex landform.

利用风速频率瑞利分布对平均风速进行均一化，提出相当风速的概念；

Standardized the wind speed by Rayleigh frequency distribution, a concept named equivalent wind speed was presented;
