Abstract:At present,in the arid wind-desert region,by the means of constructing forestation,developing to defend and control the sands is the main technical measures by which we can carry on the ecological construction and the preventing and controlling land degeneration.Therefore,through selecting the symbol target of soil structure,the moisture content,the nutrient,the vegetation as the appraisal targets,which showed land degenerated or not,we studied these indexes changes after constructing the artificial Caragana intermedia in the degeneration sand of arid wind-desert region.The results showed: in the arid wind-desert region of Yanchi,Ningxia,constructing suitable density artificial Caragana intermedia(1 665 clump /hectare,2 490 clump /hectare) could increase the vegetation fraction,comprehensively improve the soil physical and chemical property,the soil moisture condition as well as the stability of the vegetation community in the degenerated sand.
