%X 为了探讨不同灌木植物在粗粒沙丘的适应性，在石羊河下游红崖山水库以东流动粗粒沙丘进行沙木蓼、梭梭、沙拐枣、霸王、沙冬青、柽柳栽植选择试验，3年试验结果表明：6个树种成活及保存率从高到低依次为霸王 &gt; 沙木蓼 &gt; 沙拐枣 &gt; 梭梭 &gt; 沙冬青 &gt; 柽柳；新枝生长量从高到低依次为沙木蓼 &gt; 沙拐枣 &gt; 霸王 &gt; 沙冬青 &gt; 梭梭 &gt; 柽柳；冠幅盖度从高到低依次为沙木蓼 &gt; 沙拐枣 &gt; 柽柳 &gt; 霸王 &gt; 沙冬青 &gt; 梭梭；植物利用水分能力从高到低依次为霸王 &gt; 沙木蓼 &gt; 柽柳 &gt; 沙拐枣 &gt; 沙冬青 &gt; 梭梭。可见沙木蓼、沙拐枣、霸王对干旱沙漠区粗粒沙丘均有较强的适应能力，从成活率、保存率、生长量、冠幅四项指标综合分析，沙木蓼表现最好，沙拐枣、霸王次之，3个树种可在粗粒沙丘造林中推广应用。梭梭不适宜在粗粒沙丘上正常生长。<br />
In order to explore the adaptability of different shrubs in coarse-grained sand dunes, we planted selection experiment on the flowing coarse-grained sand dunes east of Hongyashan Reservoir in the lower reaches of Shiyang River to carry out the planting selection test of Polygonum sylvestris, Haloxylon ammodendron, Saguaro jujube, Bawang, Ammopiptanthus mongolicus and Tamarix. The results of the three-year test showed that the survival and preservation rates of the six tree species from high to low were Bawang &gt; Polygonum sylvestris &gt; Shaguaia jujube &gt; Haloxylon ammodendron &gt; Ammopiptanthus &gt; Tamarisk; the growth of new branches from high to low was Polygonum sylvestris &gt; Shaguazao &gt; Bawang &gt; Ammopiptanthus vulgaris &gt; Haloxylon ammodendron &gt; Tamarix; the crown coverage from high to low was Polygonum saguai &gt; Shaguazao &gt; Tamarix &gt; Bawang &gt; Ammopiptanthus vulgaris &gt; Haloxylon; plant water utilization capacity from high to low was Bawang &gt; Polygonum sylvestris &gt; Tamarisk &gt; Shaguaia jujube &gt; Ammopiptanthus ammoides &gt; Haloxylon ammodendron. It can be seen that Polygonum sylvestris, Shaguaia jujube, and Bawang have strong adaptability to coarse-grained sand dunes in arid desert areas. From the comprehensive analysis of the four indicators of survival rate, preservation rate, growth, and crown width, Polygonum sylvestris performs best. Shaguazao and Bawang are the next, and the three tree species can be popularized and applied in the afforestation of coarse sand dunes. Haloxylon ammodendron is not suitable for normal growth on coarse sand dunes.
