Abstract In Horqin sandy land, the distribution of fixed dunes, semi\|fixed dunes, moving dunes and marshland is alternate. The spatial characteristics of soil water are particular in the special marshland\|dune areas. In this paper, field survey and laboratory experiment were conducted to study the soil moisture variation in different landforms. The spatial differentiation characteristics of soil moisture in fixed dunes, semi\|fixed dunes, moving dunes and marshland have been got and compared, and their stratigraphic maps were obtained based on soil moisture dynamics. The study has significance to open out the variation rules of soil water and the relation with landforms in Horqin sandy land.
