摘　　要：通过对浑善达克沙地固沙带风速、输沙量的测定,分析了固沙带内的风速、下垫面性质的变化以及风沙流结构特征,进一步阐明了固沙带的防护效益和设计合理性。结果表明,浑善达克沙地的固沙带是公路沿线两侧形成植物能够适时发芽、生长的前期保护带,使公路沿线两侧植物最终能形成稳定的植物群落,是防护体系中实现持久生态防护的重要功能带。The wind velocity, underlying surface characteristics and the sand flow structure in the sand-fixation belt were analyzed through determining wind velocity and sediment discharge of stabilizing belts in Otindag sandy land, the protective benefits and rational design of stabilizing belts were further clarified. The results indicated that the stabilizing belts in Otindag sandy land were prephase protection bands which plants along two sides of the highway could timely bud and grow, and stable plant commnunity was formed fmally.So the stabilizing belt is the important function belt of realizing persistent ecological protection in protective system.
