中文摘要: 风蚀起沙是开展沙尘气溶胶和沙尘天气研究的基本问题。从风蚀起沙的机制、粒子
运动形态、起沙条件、沙尘通量等几个方面,回顾了我国在风蚀起沙方面的主要研究结果,
对开展这方面研究的难点问题开展讨论。介绍了计算临界摩擦速度的不同方法,并对不同研

Abstract:Wind eroded dust is an essential issue in studying dust aerosol and dust weathe
r. From several aspects, such as the mechanism of wind eroded dust, configurati
on of particle motion, condition for dust emission, and dust flux, the major res
ults of the researches on wind eroded dust in China have been reviewed and the
difficult points and issues have been discussed. Different methods
for calculating the threshold of critical friction velocity and comparing the c
ritical friction velocity of the observation are described from different resear
chers in different locations. Finally, three suggestions have been presented on
how to improve the precision of research results based on observations and the c
omparability of
different research results. First, to establish a more detailed geography, topography and soil information system. Second, to ma
ke use of the advantages of satellite observations, and to set up the ground ba
sed observing systems for the comparison and calibration of satellite remote sen
sing results. The third is to standardize the observation methods and processes
t
o fully utilize the operational observational data to improve the comparability
of observation.
