Taking Liudaogou small watershed as an example,based on simulative experiment from laboratory and field observation,attempts to establish wind erosion loss prediction model which are furthur used to estimate the amount of wind erosion loss and wind erosion modulus.It is found through the model estimation that the wind erosion modulus in Liudaogou smallw atershed is 1887.27t/(km²·a) ,corresponding to 1.25mm/a,close to the severe erosion type.If the meam erosion modulus of this area is 25000t/a,the percentage of wind erosion out of total erosion is 7.55%,and the ratio of wind erosion to water erosion is 1∶12.25.Of the total erosion,99.98% is concentrated in spring and 99.30% is concentrated in April and May.The wind erosion season is followed by water erosion season,constituting severe erosion.
