根据地震滑坡数据资料，基于贡献率分析法和极差分析法，分析了坡体组成、坡度、坡型、斜坡坡向与地层倾向差以及斜坡坡角与地层倾角差共五个坡体结构因素对地震滑坡发育的贡献率。研究表明：坡体结构不仅决定着滑坡的空间分布，而且控制着地震滑坡面积、体积及变形长度；斜坡坡角与地层倾角差、坡度的贡献程度最高，坡体组成的贡献程度中等，坡型、斜坡坡向与地层倾向差的贡献程度最低。研究结果可为以后的滑坡研究及防治提供借鉴参考。

The paper refers to the data available concerning the earthquake landslides occurred in the past several years and applies both the contributive-rate analysis and range analysis to look into 5 structural factors-namely slope composition ( M ) ,slope gradient ( α) ,slope type ( T ) ,the difference between the slope aspect and the stratum trend ( θ1 ) ,and the difference between slope gradient and stratum obliquity ( θ2 ) -and their contribution to the occurrence of earthquake landslide. The results indicate that the slope composition affects landslide's spacial distribution,the area,volume and the deformation length. At the same time,it is noticed that the slope gradient and the difference between slope gradient and stratum obliquity are the two most influential factors among all five,followed then by slope composition,while slope type and the difference between slope aspect and the stratum trend are proven to be the least contributive. The study may be of value to the landslide research and its the conclusion of its countermeasures.
