中文摘要	准噶尔盆地南缘处于沙漠绿洲交汇处,生态环境脆弱,当地植被是"三北"防护林的重要组成部分,冬季降雪融化形成的水源,是当地沙漠植被赖以生存的主要组成部分之一.本文根据在当地沙丘多点取土,测得沙丘阳坡、背阴坡和沙谷的冬季冻土深度分别13 cm、29 cm、32 cm;利用烘干法测土壤质量含水率,计算出沙丘阳坡、背阴坡和沙谷的累积含水量分别为1.3 mm,2.1 mm,1.67 mm;同时测量三点的植被覆盖率变化,得出当地沙漠不同地形的含水率变化和植被覆盖率的关系,为当地生态建设提供数据支持.
英文摘要	Southern margin of Junggar Basin lies in the desert oasis interchange area and has fragile ecological environment. The local vegetation is an important component of the "Three North" shelter belt, and the water source melt by the snow in winter is one of the main components for the local desert vegetation to survive. This article collected some soil samples in sand dunes at different points, and determined that the depths of frozen soil in the sunny dunes and shady spot of dunes and valley were 13 cm. 29 cm, 32 cm respectively. Measuring the soil water content by using drying method, calculated out the cumulative soil water contents in three positions were 1.3 mm. 2.1 mm. 1.67 mm respectively. At the same time, the article measured the change of vegetation cover index at different positions, obtained the relationship between change of water content and the vegetal cover in local desert terrain, which provides local with data support.
