A sand control method using warp-webbing grid net is provided, which comprises preparing a warp-knitted net from plastic monofilaments and fixing piles in desert. The method is characterized in that the upper end of the fixed pile has an opening, each warp-knitted net is embedded vertically in the opening to form a vertical net, the vertical nets are conducted in Z-shaped arrangement (90 DEG angle), all the fixed piles are shared by two adjacent warp-knitted nets except the boarder piles, and the adjacent warp-knitted nets are combined to form a meshed sand barrier. The warp-knitted net is made of weather-resistant modified polyethylene monofilaments by warp flat lining and weft chain knitting, and has an air-permeability of 30-45percent and a height of 20-40 cm. The invention helps for sand control and has the advantages of reduced consumption of raw material, low processing cost, easy construction and maintenance, firm fixation, high strength of net, good wind-breaking and sand-fixing effect, and restore of
