Abstract:: The study on the influence of different species arrangement models on anti-scourability of soil was carried out in Beichuanhe watershed, datong county, Qinghai, through five models of Converting Cropland to Forest selected in low mountain areas and high mountain areas respectively.The main conclusions are as following:in low mountain areas, the index of soil anti-scourability is in evidently direct proportion to the existent masses of litter layer.The index of soil anti-scourability of model D (Hippophae rhamnoides ssp.sinensis) ranks first, up to 1.136 s/g, model E (Caragana korshinskii)is less than others, up to 0.385s/g, in different species arrangement models.In high mountain areas, the index of soil anti-scourability is in evidently direct proportion to the degree of aggregation and the total pore space.The index of soil anti-scourability of model F (Picea crassifolia) ranks first, up to 1.652 s/g, model J (Populus cathayana+Hippophae rhamnoides ssp.sinensis)is less than others in different species arrangement models.
