Summary:Sand drift disasters are mainly manifested in the destruction by wind-sand currentto engineering installations, rapid aggravation of soil erosion, land desertification,etc. The reason for the damage lies in the fact that moving sand grains obtain largequantity of energy under the action of wind force. However, judgement of the intensi-ty of sand drift depends on the determination of energy accumluated by wind-sand cur-
