The study of land soil water changing patterns on the north of Wulanbuhe Desert showed that there are three levels of space changes in moving sands soil water: dry sand layer of surface ,moisture acute changing layer, and stable moisture layer. The physical properties of semi-fixed sand, yellow sandy layer and grey-white layer are similar almost, only color is different due to the water content. There are four districts of immobile sandy land according to the changing trend of water content from the surface land to down:1.from surface land to clay soil;2.instable leak layer which is not influenced by underground water and rainfall evaporation;3.the raising higher layer of un saturated capillary;4.the raising higher layer of saturated capillary. The soil water in lowland sand dune in space was divided into: the frequent changing layer, the potential supplying layer and the relative stable layer.
