摘　　要：砒砂岩区水土流失十分严重，不仅产沙量大，而且粗沙比例高，对黄河危害极大。通过多年的探索，总结出沙棘治理砒砂岩的布局：沟坡布设沙棘护坡林、沟道坡脚布设沙棘挡沙坝、沟底布设沙棘拦沙坝。沟底拦沙坝布局根据沟道洪水大小确定。同时在砒砂岩沟道使用沙棘种植专用工具，提高沙棘种植工效3～5倍，同时提高了沙棘种植的质量，在寸草不生的砒砂岩上，沙棘种植成活率可达90％以上。Soil erosion in soft rock area is very serious, it not only producing large amount of sand, but also got a high percentage of rough sand. This is extremely harmful to Yellow River. Based on many years study, we find out a layout of governance soft rock by seabuckthorn. At the same time, by special sea buckthorn planting tool in soft rock channel can improve the plant efficiency for 3 to 5 times therefore improve the planting quality. Seabuckthorn survival rate can reach over 90%.
