摘　　要：遵循沙石荒漠植被形成由草本灌木乔木的演替规律 ,从筛选适宜沙石山地生长的先锋植物入手 ,结合必要的工程措施 ,创造植物生存的基本生存条件。通过种植兼有草本和灌木特性的中秆型禾草类芦(Neyraudiareynaudiana) ,很快绿化了沙山 ,固护了沙坡 ,改良了沙质 ,为灌木。Neyraudia reynaudiana the plant of sand land, is selected to afforest the sand hill washed over by Gaolin mine.The planting methods such as“small platform, small pit, soil building, fertilizer supply, wild seedling planting etc.”can be used to improve its survival rate, to promote its sprouting and growth. In the first year of planting, it grows to an average height of 1 3 m, with a covering rate of 60%～70%. The fast occupacy of N. reynandiana over the sand hills and the deserted mines is making a more important role in the aspect of ecological function such as protecting slopes and consolidating sands.
