This paper deals with the environmental factors and the damages of wind erosion occurring in sandy lands of shahe area of Yucheng County in Shandong Province.The practical resups showed that such techniques as water conservancy project,planting trees and grasses,biological mulching and stereoscopic farming measures could effectively stabilize sand surface,reduce wind velocity and increase the resistance to wind erosion,thus halting the wind-sand hazards.In addition,the paper also discusses the wind erosion mechanism and the laws of wind-sand activities,which may provi}le a basis for the agricultural development of sandy lands in the Huang-Huai-Hai plain.
