【Abstract】 By means of on the spot investigation and contrastive analysis,the back slope of BeiWenquan is divided into five sample districts according to the diversity of the material composition and structure on the surface of the earth.Secondly,five factors,which greatly influenced the back slope stability:geology,topography,climate,vegetation and human activity,are chosed.And the sub factors,which were ranked at four stages on the important hierarchy,are selected.Thirdly,the gradient analysis to weight these evaluation factors and sub factors separately are adopted.Finally,a comprehensive evaluation on the five sample districts is given.更多还原
