Abstract: In order to raise the utilization ratio of forage shrub forest, the characteristics of the shrub species(Caragana intermidia, C.korshinkii,Hedysarum scroparium, H.fruticosum, H.fruticosum Pau. var. Laeve, Atraphaxisbracterate, Tamarix chinensis, Artemisia ordosica) were studied. the results showed that 8 shrubs can resist the cold or extremely hot weather. Their lateral roots were abundant. Their branches and leaves contained many coarse fat, coarse protein, all kinds of nutrient elements and 19 amino acids. The change law of their yield and the relation between yield and site, density, age, size, cutting were also studied.
