绿洲-漠交错带是植被恢复的一个重要区域，而植被恢复的关键又是了解沙丘土壤水分的变化规律。
The eco-tone between oasis and desert is a important zone for vegetation restoration. The key for vegetation restoration is to know the soil water content of dune.
由于沙丘土壤的保水性差，即使在夏秋雨季也不能有效保持水分，因此，沙丘油松林带应注意密度控制。
The density of the Pinus tree-belt at the dune site should be paid special attention to because soil water holding capacity was poorer at this substrate;
流动沙丘土壤表层蒸发量主要取决于干沙层的厚度，表现为随着干沙层厚度的增加，沙丘表层的蒸发量逐渐降低。
The evaporating capacity of surface soil in mobile dune is mostly rest with thickness of dry sand bed, with the increasing of dry sand bed thickness, the evaporating capacity reduce gradually.
