摘 要: 滑坡的易发性评价对防灾减灾工作有着重要作用,是防灾减灾的主要依据之一,其相关研究是社会发展的必然要求。广泛搜集了已有滑坡易发性评价文献,统计分析了研究中因子选择与因子组合的一般特征,从评价因子选择、因子赋值、因子权重、因子组合等方面进行综述。结果显示,在不同研究背景条件下,所选取的因子有一定差异,总体上工程地质岩组、坡度、高程、坡向是选择比例最高的因子,且为最常用的基础因子组合,随着因子数量的增加,断层距离、水系、人类活动、植被覆盖指数(normalized difference vegetation index,NDVI)、地震动峰值加速度(peak ground acceleration,PGA)等因子依次被考虑。最后分析存在的相关问题并探讨进一步的研究内容。
关 键 词: 工程地质学;滑坡易发性评价;综述;影响因子;统计特征

Abstract: The research of landslide susceptibility assessment plays an important role in the prevention and reduction of natural disasters. It is one of the main basis for disaster prevention and mitigation. The related researches are the necessary requirement for social development. This study is based on the existing researches about landslide susceptibility assessment. Statistics count and analysis of the existing result about factor selection and combination. Summarizing the research of landslide susceptibility impact factor, including factor selection, factor assignment, factor weights, factor combination. The result shows that the selection of impact factor displays certain difference in different background conditions. In total, the selection proportion of geological rock conditions, slope angle, elevation and slope aspect are the highest, followed by distance to fault, water index, human engineering activities, normalized difference vegetation index (NDVI), peak ground acceleration (PGA), are taken into account respectively with the increasing number of impact factor. Lastly, analysis the existing issue, and discuss the issue that need to further study.
Key words: engineering geology; landslide susceptibility assessment; review; impact factor; statistical characteristics
