| 摘 要： | 本文讨论了农田中风速的水平和铅直分布的基本规律性。指出农田植被中的风速廓线具有上下不对称的“S”型分布。分析了农田植被中风速水平和铅直分布廓线常见模式的缺点,在理论分析和经验拟合的基础上提出了新的描述农田植被中风速的通用模式。按此模式计算的平均风速,无论水平分布或铅直廓线都与实际情况比较一致。

| Abstract: | The characteristic features of horizontal and vertical wind-speed distribution beneath crop canopy are discussed. It is found that there exists an assymmetric "S" pattern vertical profile. Deficiency of commonly used models of horizontal and vertical profiles inside crops is also analysed. A new model describing wind speed inside crops is proposed on basis of theoretical analysis and empirical fitting. According to this new model the computed mean wind speed, whether in horizontal distribution or along vertical profile, is fairly good conformity with the real data. |
