在比较和分析了目前国内外研究和应用较多的几种地质灾害评价理论和方法的基础上，对汶川县2014年landsat8遥感影像解译并提取了地质灾害信息，利用DEM数据对20014年地质灾害的面积在高程、坡度、坡向等致灾因子进行了统计。采用信息量法、层次分析法、加权信息量对汶川地区地质灾害易发性进行了评价。通过这3种评价方法的结果对比表明：采用单一的信息量法、层次分析法做地质灾害易发性评价时各有优势和不足，将多种易发性评价方法进行合理的综合应用是地质灾害易发性评价的优选方法。

Remote sensing image of 2014 landsat8 in Wen chuan was interoperated and extracted geological hazard information, geo-logical disasters was statistic in elevation, slope, aspect and other hazards in the area of 20014 by using DEM data, Based on compa-ring and analyzing the current domestic and international methods and the application of several geological hazard assessment theory and methods.Information method, analytic hierarchy recess, and reweighted information were used to evaluate geological disaster-prone areas in Wenchuan evaluation.The results of this comparison showed that the three evaluation methods showed:using a single method, such as information and AHP to do logical disaster-prone evaluation had advantages and disadvantages.The multiple sus-ceptibility evaluation methods reasonably comprehensive application is the preferred method to evaluat geological disaster.
