摘      要：Sand transport by wind plays an important role in environmental *** the sand-transport rate model has been of continuing significance,because the majority of the existing models relate sand-transport rate to the wind-shear ***,the wind-shear velocity readapted to blown sand is difficult to determine from the measured wind profiles when sand movement occurs,especially at high wind *** wind tunnel tests were carried out to reformulate the sand-transport rate model,followed by attempts to relate sand-transport rate to parameters of wind velocity,threshold shear-velocity,and grain ***,we validated the model based on the data from field observations.
