摘　　要：对黄土高原残塬沟壑区荒坡治理生物措施与工程措施配置模式及草的生态效应研究结果表明 ,草适应性广 ,生长势极强 ,是荒坡治理生物措施与工程措施配置模式的优良先锋草种 ,与相应的林木 (经济、生态林 )组合其水土保持及保水效应良好 ,且利于幼树成活生长。The deposition model of biological and engineering measures and eco-effect of Humulus scandus are preliminarily studied for sloping wasteland control in this paper. The results show that the Humulus scandus has high vigorous adaptability and is one of the good pioneering grasses for sloping wasteland control. In combination with the trees,the grass has a great efficiency on water and soil conservation and is favorable for sapling growth also.
