摘　　要：The water-saving technique, which prevents water from downward seepage and salts from upward, was proposed on the basis of analysis of the two major processes of material differentiation in the desertification process of semiarid zone. The organic-inorganic complex materials are water emulsion, which are composed of the polymer and clay, possesses a clay penetrability and can penetrate coarse sand to react with calcium ions from soil to form a gel waterproof layer, which can prevent water from seepage.The water-saving technique, which prevents water from downward seepage and salts from upward, was proposed on the basis of analysis of the two major processes of material differentiation in the desertification process of semiarid zone.
