Abstract

Wind and sand control is an effective method to prevent land desertification and protect farmland, pastures, transportation and settlements from wind and sand flows and dunes. The surface of sandy land is exposed, wind speed is high, sandy land surface activity is frequent, wind and sand activity at the edge will harm farmland, and the gradual invasion of sand flow will cause the elevation of farmland. China's arid zone is vast and more than 1/4 of the country has desertification, so it is one of the most serious countries in the world suffering from desertification. The high vertital sand barrier laying vehicle working principle is to increase the roughness of the desert surface and artificially change the wind speed profile, so as to weaken the surface wind speed, reduce the wind force and improve the survival rate of sand-fixing plants. The surface roughness of the area where high vertical sand barriers are used for wind and sand fixation can be up to 200 times more than other areas, and the wind and sand flow rate can be as low as one percent or less than other areas.
