The resistance to soil erosion on the soil surface is higher than that of the subsurface.The statistical analysis demonstrates that soil volume weight (v), quantity of >0.25mm total aggregate (a) and infiltration coefficient (i) are the main factors that determine soil erodibility(k). the relationship between k and v,a,i can be described by the follwing regression equation; k= 27 .6261-14 9964v -0.1382a-2.5911i.

Besides the weter stable aggregate content is the best air-dry ratio (excluding sandy loam soil) is the next soil anti-erodibility index in eoess Plateau. Other indices based on microaggregate contents do not reflect precisely the soil anti-erodibility in this area. The soil anti-erodibility increases from north to south in the Loess Plateau.
