Abstract: It is generally considered that sand bury is a necessary condition to the growth and the reproduction of native plant in sandy desert.But,if sand-binding plantation is constructed in the sites without sand bury,what results may be taken?A cultivation experiment has been conducted to find the possibility of establishing sand-binding plantation in the shallow groundwater sites in the hinterland of Taklimakan Desert,where are often not suffered with sand bury and the salinity in sand layers is great.Observation in this site for seven years showed that the main factors limiting the growth of sand-fixation plants are not soil water content and soil salt content,but the shallow groundwater table(range from 0.8 m to 1.0 m) with high salinity along Tarim Desert Highway.In the other word,the cultivated plants always absorbed the groundwater with high salinity and could not regulate the accumulated salts of their body;As result,the plants died out.So it must be cautious to establish sand-binding plantation in the regions with shallow groundwater table and high soil salinity as well as not suffered with sand bury.

Key words: Taklimakan Desert, sand bury, sand-binding plantation
