Abstract: Practice in China has proved that the stabilization of shifting sand under no irrigation in the desert pasture transition zone with 200~300 mm precipitation is not only possible but also successful. In Shapotou, situated at the southeastern Tengger Desert, there is only 186.2 mm annual average precipitation. The shifting sand dunes along the Baotou-Lanzhou Railway in Shapotou section have been successfully stabilized by planting sand fixing vegetation in checkerboards. Artemisia odosica, with the most strong re generation ability and easily to become community so that to stabilize sand dune longer, is the most advantageous sand fixing plant, which ought to be the preferential specie in shifting dune s stabilization of this area.

Key words: shifting dune stabilization, mechanical sand fixation, biological sand fixation
