摘　　要：滑坡作为最常见、最重要的地质灾害类型之一,常常给人们的生命财产安全带来巨大威胁。本文总结了前人基于GIS滑坡灾害易发性评价的研究方法,分析了统计分析法中层次分析法、频率比法、证据加权分析法和逻辑回归,数学模型法中的神经网络模型、模糊综合评判、信息量模型、支持向量机模型等常用方法在应用中的优势和局限性,在此基础上归纳出针对不同形成机理的滑坡易发性评价思路,为滑坡地质灾害评价和预测研究提供参考。As one of the most common and important types of geological hazards,landslide is a huge threat for human life and property.This article summarizes the evaluation methods of former research of landslide hazards based on GIS,analyzes the advantages and limitations in the application,of the methods commonly used,such as statistical analysis method of analytic hierarchy process and frequency ratio method,weights of evidence model and logistic regression,the method of mathematical model of the neural network model,fuzzy comprehensive evaluation,information model,support vector machine model.On the basis of summing up the liability according to different formation mechanism of landslide evaluation idea,provide a reference for landslide geological hazard evaluation and prediction research.
