There are distinct vertical changes of soil moistur in mobile sand dune from 0 to 200 cm, 0-20 cm is surface dry sand bed, 20-140 cm is variational layer of rainfall effect, thereinto, 20-40 cm is smart variety layer of rainfall effect, below the depth of 140 cm is deep-seated stable layer.
科尔沁沙地流动沙丘0-200cm深度土壤层的水分具有明显的垂直变化，0-20cm为表层干沙层，20-140cm为降雨影响变化层，其中20-40cm为降雨影响剧变层，140cm以下为深部稳定层，受地面气象要素的影响很小；流动沙丘丘顶由于风蚀作用，干沙层厚度变薄，同时迎风坡底坡和中坡土壤细粒部分在丘顶沉降堆积也一定程度的降低了丘顶表层土壤水分的蒸发，所以丘顶20-140cm深度的土壤水分状况总体趋势要好于迎风坡中坡的和背风坡中坡的与底坡的；背风坡底坡的土壤水热条件相对较好，人工栽植固沙植物，如差巴嘎蒿和小叶锦鸡儿等耐旱、抗沙埋的沙生植物，可以起到固定流动沙丘的作用；从土壤容重的空间变化来说，虽然没有明显的规律性，但是可以间接用于指示流动沙丘的移动状况，同时也说明由于流动沙丘经常处于风蚀、搬运、堆积的运动状态下，其土壤容重的变化也趋于复杂化和无规律性；迎风坡底坡田间持水量与容重随深度存在极显著的负相关，其它部位存在显著的负相关；说明容重大，田间持水量小；容重小，田间持水量就大。
