【Abstract】 This paper firstly divides the back slope of Beiquan into five sample districts according to the diversity of the material composition and structure on the surface by means of on the spot investigation and contrastive anatysis Secondly, five factors are chosen which greatly influenced the back slope stability: geology, topography, climate, vegetation and humanactivity, and seclect ten subfactors which were rnked at four stages on the important hierarchy Thirdly, the gradient analysis is adopted to weight these evalutive factors and subtactors separately Finally, a comprehensrve evamation on the five sample ditricts is carried out更多还原
