摘　　要：黄土滑坡、崩塌是黄土地区最为严重的地质灾害.根据统计有1/3的滑坡发生在黄土地区,黄土地区的滑坡、崩塌的发育、发展主要与其地质因素、区域气候、人类工程活动等因素关系密切.调查研究表明黄土滑坡、崩塌地质灾害具有以下几个方面的规律:1)地层层位的选择性;2)地形地貌的特殊性;3)时间分布的周期性;4)人类活动强烈区.Loess landslide and landslip are most serious geology disasters in loess region,1/3 o f which took place in the loess region.The growth and development of loess landslide and landslip are closely related with its geology factor,regional climate and engineering activities of human beings,etc.The distribution regularities are as follows： Through investigate research shows the loess landslide and landslip geology disaster to have several regulations： 1） the selectivity of stratigraphic position;2） the particularity of landform;3） the periodicity of time;4） areas where human beings exercise intensely.
