摘要
在详细研究国内外基于GIS的滑坡灾害危险性分析现状的基础上,以GIS为操作平台,选取南水北调西线一期工程区某库区为研究对象,使用信息权法对研究区滑坡进行危险性评价,指出该方法改进了传统信息量模型不考虑因子权重,将变量提供的信息量作为信息权看待的不足,使评价的结果更加合理可靠。
Based on a detailed study of the domestic and international research status about GIS-based landslide hazard＇s risk analysis, with GIS as the operating platform, this article choosed one reservoir area of the first stage of the west route of the South-to-North Water Transfer Project for study. And made landslide risk appraisal of the study area with the law of information weigh. This method improving the traditional information model didn＇t consider the weight of the factor and treated the information provided by variable as the weigh of information, which made the results of the evaluation more reasonable and reliable.
