Abstract: A comparison was made on the adaptability,biomass,drough-tolerance,forage composition and nutritive values between 5 psammophyte shrub species and the traditional forage shrub and forage grass species in Wulanbuhe Desert.he results showed that therewere sigriificant differences in height growth and above-ground growth between Hedysaru mscoparium,Haloxylon ammodendron and Calligonum arborescens of different production areas;the above-ground biomass of both ,C.arborescens and H.fruticosum var. monglicum were lower than that of the control(Tamarix ramosissima)by 10.69%and 18.87%,but that of H.scorparium,H.ammodendron and Caragana korshinskii was higher than that of the control by 16.98%,27 04% and 2.64% respectively.The drought tolerance of the selected 5 tree species was higher than that of Populus gansuensis and P.simonii,and the coarse fat,coarse fibre and non-nitrogen exudate of their leaves were higher than those of poplar,willow and ulmus. Their forage composition and nutritive values were also higher than those of the traditional forage crops,so the cultivation of psammophyte shrub species is reliable method to develop animal husbandry.
