摘　　要：在武威沙丘迎风坡设置了草把型、双眉式一字型、直角型和方格型4种稻草沙障,并于障后栽种梭梭、花棒、沙拐枣,经对比试验,得出了结论:①武威半固定沙丘地宜于治沙造林,且固沙作用:方格型>直角型>(双眉式)一字型>草把型,此外,设置“草方格+一把草”沙障,成本为设全方格型的45%~57%;②设置(双眉式)一字型沙障,三种苗木第三年造林保存率分别为63%、77%、73%,花棒成效最好;③用挖穴、缝植和钻孔三种方法植苗造林,钻孔植苗最省力、高效;造林时间早春好于秋末和晚春。Four types of sand barriers, straw handle type, double eyebrow one-line type, right angle type and square type were set up on the windward slope of sand dunes in Wuwei City. Haloxylon ammondendron, Hedysarum scoparium and Calligonum mongolicum were planted after the barriers. Through the comparative test, it is concluded that:① Sand control and afforestation were suitable for semi-fixed sand dunes in Wuwei City, and the effect of sand fixation was: square type > right angle type >(double eyebrow) one-line type > straw type. Besides, the cost of setting up "straw checkerboard+ a wisp of grass" sand barrier was 45-57% of that of setting up full-square type;②Setting up sand barrier with(double eyebrow) one-line type, the afforestation survival rate of three kinds of seedlings are 63%, 77% and 73% in the third year, respectively, and the survival rate of Hedysarum scoparium is highest;③ Afforestation of seedlings is planted by three methods: digging holes, sewing planting and drilling, and drilling seedlings is the most labor-saving and efficient;afforestation time in early spring is better than late autumn and late spring.
