摘　　要：踏郎属多年生豆科植物,在沙地缓冲区用踏郎建立沙障,控制流沙向内部蔓延。浑善达克沙地东缘小流域内广泛分布有斑状沙地。由于风水交互侵蚀作用,给小流域治理带来了极大的困难。采用踏郎再生沙障技术,可提高小流域内的固沙效益,加快斑状沙地的植被营造速度,为该地区水土保持生态建设提供科技支撑。Hedysarum Laeve is a perennial legume. In Sand buffer zone Sand-Stabilization of Hedysarurn Laeve is established for controlling the quicksand to internal spread. In small watershed at the eastern edge of Hunshandak sand, there is a broad distribution of macular-sand. With the water and wind interactive erosion, comprehensive control of small watershed was extremely difficult. Using the sand-stabilization of Hedysarum Laeve technology, small watershed can improve the sand-fixation efficiency, as well as speed up the macular-sand vegetation create, which will provide the technical support for soil and water conservation, ecological construction in the region.
