Abstract: Chaidamu basin becomes one of the emphasis in the West Development of China for its abundant mineral resoures. But its ecological environment is very fragile,the facilities are largely damaged by wind corrasion and wind-drift sand hazard. All those made the environment worse and worse. On the basis of detailed surveying and study. The paper analyses the mechanism of wind corrasion and wind-drift sand hazard, and puts forward synthetic control measures. It provides theoretical basis to control desertification and to protect environment inside the basin.
