中文摘要	以亚玛雷克沙漠丘间地猫头刺(Oxytropis aciphylla Ledeb.)及小叶锦鸡儿(Caragana microphylla Lam.) 2种典型灌丛及其风影沙丘为研究对象,采用摄影测量法获得了灌丛及其风影沙丘野外测量数据,分析了2种灌丛结构及其与风影沙丘间的关系。结果表明:在生境相同的情况下,猫头刺的平均积沙面积远小于小叶锦鸡儿,但平均积沙量却大于小叶锦鸡儿。植株高度、冠幅及植株迎风面剖面面积均为控制灌丛积沙效果的关键特征参数。在灌丛大小相近的情况下,猫头刺灌丛结构与风影沙丘特征参数间相关性更大些,积沙效果要优于小叶锦鸡儿。2种灌丛高度及灌丛迎风面剖面面积与其风影沙丘底面积、沙丘长度与沙丘体积总体上具有较高的拟合程度。2种灌丛的阻沙能力随着灌丛高度和灌丛迎风面剖面面积的增加呈不同增加趋势,且猫头刺阻沙能力大于小叶锦鸡儿。
英文摘要	In this study, two shrub species, i. e. Oxytropis aciphylla and Caragana microphylla,and their wind-shadow dunes were taken as the study objects to analyze the relationship between the structure of the two typical shrub species and their wind-shadow dunes. The results showed that,under the same habitat conditions, the average sand deposition area of O. aciphylla was much smaller than that of C. microphylla,but the average deposited sand volume of the former was bigger than that of the latter. The plant height,canopy and sectional area of windward side of the plants were all the key characteristic parameters affecting the sand-deposition effect of the shrubberies. Under the similar size of shrubberies, the correlation between the structure of O. aciphylla shrubbery and the characteristic parameters of the wind-shadow dune was higher than that between the structure of C. microphylla and the wind-shadow dune, the sand-deposition effect of O. aciphylla shrubbery was better than that of C. microphylla shrubbery. Holistically, the fitting degree between the plant height and the sectional area of windward side of the two typical shrub species and length and volume of wind-shadow dune was high. Sand trapping capability of the two typical shrub species was in an increase trend with the increase of shrubbery height and of sectional area of windward side of the plants,and the sand trapping capability of O. aciphylla was higher than that of C. microphylla.
