摘要:
针对多数研究都是以摩阻风速表征地表输沙量，而气象站风速观测通常是10 m或12 m高度的平均风速，因此在利用气象站风速观测资料来评估大范围或者某一特定区域较长时间的地表输沙量时，首先需要解决摩阻风速与平均风速的转化关系。然而，很少见到相关研究报道。借助风洞实验和2003年春天在北京郊区获得的9种不同下垫面的野外风沙观测数据，对摩阻风速与平均风速的转化关系进行了探讨，认为它们满足线性关系。
Abstract:
Most researches express the flux of sand transporting quantity with a power function of friction wind velocities and the wind velocities observation in weather station is the mean velocities in 10 m or 12 m height, so the first key question is how to establish the relationship between friction wind velocities and the mean wind velocities at some height when we would assess the sand transporting quantity for large area or for a specific region for long time by making use of the observation data of wind velocities with long time in weather station. Little research on the question has been published. The data from wind tunnel experiment and filed wind sand observation from 9 different earth surfaces in Beijing outskirts in 2003 are used to discuss the transferred relationship between friction wind velocities and the mean wind velocities at some height. The result shows that they satisfy a linear relationship.
