The oasis farming areas on the edge of the Southern Xinjiang desert are one of the most severely affected areas by wind-blown sand hazard in China， resulting in huge economic losses via causing seedling death， stem collapse， branch breakage， flower and fruit falling especially at the stage of cotton seedling and at the stage of flowering and fruiting of fruit trees. Therefore， conducting studies on the hazard and prevention and control of wind-blown sand in Southern Xinjiang has important practical significance and regional economic value. This article reviewed the structural characteristics of wind-sand flow in farmland， sorted out two forms of hazard caused by wind-blown sand to crops， and summarized the mechanisms of crops protecting wind-blown sand and the status of studies on prevention and control measures of wind-blown sand. Finally， the problems existing in studying wind-blown sand hazards of crop were pointed out. The focus of study and the development prospects of hazards and control of wind-blown sand of crops in Southern Xinjiang in the future are proposed based on the types of crops and the environmental characteristics of wind-blown sand in Southern Xinjiang，
