Using the finite element strength subtraction method,from the calculation scope,internal friction angle,cohesive force,soil weight, slopeheight andgradient and other aspect,researched the influence of calculation of sensitivity parameters to mountain slope stability safety coeffi-cient,the results showed that the influence of soil cohesive force,internal friction angle and weight was the most sensitive to slope stability,the influence of slope angle andgradient took second place,the influence of calculation was smaller.%采用有限元强度折减法，从计算范围、内摩擦角、粘聚力、土体重度、坡高与坡度等方面，研究了计算敏感性参数对山区边坡稳定性安全系数的影响，结果表明，土体的粘聚力、内摩擦角和重度对边坡稳定性的影响最为敏感，坡角与坡高的影响次之，计算范围的影响最小。
