摘　　要：本文基于黄土斜坡稳定性的实际资料,利用信息分配、模糊一二级近似推论及信息集中等原因建立了一套黄土斜坡稳定性的评价方法。用这套方法对一些黄土斜坡(非母体)稳定性进行了验证,其结果与实际情况一致。本方法已应用于兰州市滑坡防灾规划和皋兰山三台阁北侧几个滑坡及斜坡稳定性的研究中,效果良好。Ln the paper,authors are rolling the real data of slope stability in loess areas. A set of methods of evaluating slope stability is established by the principles of information distribution,fuzzy inference theory of I , Ⅱ grade and information concentration. The loess slope stability is classified into 4 sorts:stable slope,stable slope in the main,non-stable slope and non-stable slope ex-temely. Evaluated parameters are characters of loess(c,(?) value) ,the angle of slope,the height of slope,the mean value of annual rainfall,the few slope stability and those near San taige. Pagoda on top of Gaolan Mountain in Lanzhou City are evaluated by this method,and this method has also been applied in the landslide prevention planning of Lanzhou City,
