After a comprehensive analysis for the influential factors like anti-erodibility chemical constitutes, mineral components and micro-structure characteristics of Pisha-sandstone, by combining AHP grey correlation analysis, quantitative comparison 5 types Pisha-sandstones in Ordos is made on basis multi-layer assessment mode. The result shows that, from point view, order those is: Pink sandstone, celadon purple sandstone commixed sandstone. For evaluation process adopts simple method, direct, reasonable practical given, which also identical to field survey soil rock erosion problems. Consequently, research Pisha-sandstone's issue turned qualitative description stage.
