摘要 滑坡灾害的易发性评价方法和模型有很多,不同的学者又对其进行了不同的改进,形成了不同的方法。究竟哪种方法更好,还需要结合实际进行方法的比较分析。论文应用基于专家经验值的二元统计法分析了四川平武高坪铺库区(约32 km2)高程、岩性、与居民点距离、与河流距离、坡度和坡向6种因素对滑坡灾害影响,并在此基础上进行了滑坡易发性评价。 The assessment of landslide susceptibility has variety of motheds and models.This article used the bivariate statistic method based expert experience to analyze the impact of 6 factors for the landslide susceptibility in the Gaopingpu Reservoir area.The 6 factors are the elevation,litho logy,the distance from residential areas,the distance from the river,slope and aspect.The assessment of landslide susceptibility was carried out.
