By multivariate analysis, the anti-erodibility of soils nuder different vegetation forms showed signi -ficant variation. the order of anti-erodibility follows: Peashurd land soil> grassland soil > farm land soil and loess parant material. On the same soil profile, the anti-erodibilty showed deereasing tendency with the depth of the soil, the surface layer is much higher that of the subsoil. On peashrub land, the anti-erodibility of soils increased with the age of the shrubs. The anti-erodibility of ortho dark loessial soil, ortho chestnut soil and ortho sierozem was higher than that of yellow loessial soil and ortho grey-drab forest soil. An increasing tendency was found from the east to the west on hill area of loess plateau. the anti-erodibility of soils also varied correspondingly with the water stable aggregate and organic matter contents. Other indices do not reflect precisely the anti-erodibility of soils.
