Abstract: By use of wind tunnel experiment of wind erosion, the time problem in calculating soil wind erosion rate was discussed in this paper. The experimental results indicated that using the concept of wind erosion modulus to calculate soil wind erosion rate would lead to a large variation, because the wind erosion rates decrease gradually with increasing erosion time. Our experiments showed that using the concept of cumulative rates of soil wind erosion would obtain a more precise result.
