| 摘 要： | 综合环境地质学、自然地理学等学科的理论和方法，对野外实地调查及室内整理的数据进行数学模型计算，系统研究了镇雄县滑坡地质灾害的时空分布规律.基于GIS叠加分析功能，得出镇雄县滑坡地质灾害的主要致灾因子，采用滑坡确定性系数（CF）法对滑坡地质灾害各个因子数据进行量比，并根据主要致灾因子数据与滑坡形成有利级别进行多元线性回归模型的建立，最终获得适用于镇雄县滑坡地质灾害主要致灾因子的多元线性回归模型，在此基础上对滑坡地质灾害危险性进行分区，得到各个分区的分布情况.

| Abstract: | Combining multi-disciplinary theories and methods like environgeology and physiography for field investigation and mathematical model calculation of indoor collected data, this paper systematically studies the space-time distribution regularity of the geological disaster of landslide in Zhenxiong County. Based on the GIS overlay analysis function, the major disaster-inducing factors of landslide are obtained. By quantizing each factor with certainty factor (CF) method, a multiple linear regression model with major disaster-inducing factor data and landslide-prone levels which is fit for the landslide in Zhenxiong is established. With the model, this region is zoned by the distribution of risk of landslide. |
