Abstract:The influences of different psammophilic shrubs on the physical and chemical properties of aeoliansandy soil were studied in the Hexi Corridor.The results showed that total porosity,aggregate structure,storage capacity,soil organic matter,total N,available P,rapidly available K and CEC,layer thickness,litter accumulation of dry matter,water storage,and maximum water holding capacity of different forest shrubcould be ranked in a descending order as Haloxylon ammodendronforest shrub>Mongolion calligonum herbwith fruit>Hedysarum scoparium Frisch>bare sand(the control).In addition,bulk density,pH value,Ca-CO3and total salt of the soils could be ranked as bare sand(the control)>Hedysarum scoparium Frisch>Mongolion calligonum herb with fruit>Haloxylon ammodendron forest shrub.In short,the Haloxylonammodendronforest shrub could contribute greatly to soil and water conservation because of its high shrubdensity and fast accumulation rate of litters.
