严重风蚀穴（群众称之为风剥板）不均匀分布于流动沙地中，坚硬紧实，单一生物措施难以治理。经采取环坡深耥大垄，运用豆科牧草沙打旺与禾本科谷子混播的方法，使风蚀穴得到了治理，方法简单易行，并取得明显的生态效益和经济效益 Severe wind erosion points (what the masses call the wind-peeled panels) are unevenly distributed in mobile sandy land, hard and tight, and single biological measures are difficult to control. After adopting the method of deep furrows with big ridge on the slope and mixed use of legume gramineous sand and gramineous millet, the wind-eroded pit has been controlled, the method is simple and easy, and obvious ecological and economic benefits have been achieved
