Abstract
It simulates the wind erosion of soil samplers treated by different PAM with the actions of non-sand-driving wind and sand-driving wind under the conditions of different slopes and different wind speed of surface.It learns from the study that when the amount of application of PAM is 0.2 g/m~2 and 6 g/m~2 respectively,it can withstand 18 m/s non-sand-driving wind and sand-driving wind and no wind erosion happens;when the amount of application is 0.1 g/m~2,the wind erosion rate of non-sand-driving wind can be reduced by 90% ~ 98%,when the amount of application is 4 g/m~2 and surface slope smaller than 10°,it can control 18 m/s sand-driving wind and no wind erosion happens and;when the amount of application is 2 g/m~2,the wind erosion rate of sand-driving wind can be reduced by 23% ~ 99%.
