摘　　要：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。Deflation hollows located in shifting sand lands are hard to rehablitate by single biological measure. The experimental results show that it is feasible to treat deflation hollow by comprehensive method combining engineering measure and biological measure. Mixedly seeding Astgalus sadurgens and millet on deeply ploughed slope of deflation hollow has resulted in obvious ecological and economic effects.
