| 摘 要： | 略述边界层剪切湍流各区域速度廓线规律和地面粗糙分类后,对各种地面粗糙度(包括沙质粗糙度、动力粗糙度、植被粗糙度、复杂地面粗糙度、有效粗糙度)的研究现状和计算方法作了简要综述,认为动力粗糙度算式中系数A和植被或有效粗糙度算式中位移高度d将会是进一步研究的重点。

| Abstract: | Surface roughness length is an important parameter of atmospheric boundary layer. There have been major advances in the understanding of this length recently. In this review, attention is directed towards three important aspects of surface roughness: the classification of surface roughness, estimates of roughness length, and the trend of roughness study. |
