摘要
通过构建地质灾害发育强度指数和降雨强度指数，最终建立降雨型地质灾害易发程度评价模型，将全省按灾害易发性划分为高、中、低三类区域。借助ArcGis平台，用栅格数据模型（Raster）来表现评价因子的地理分布，进行深入的空间分析和处理。
By quantifying two assessment factors, intensities of geological disaster and rainfall, susceptible assessment model for geological disaster is given. Then the researchful region is zoned into three subregions based on susceptibility. The zonation processes are operated on ArcGIS desktop. The spatial distribution of assessment factors are presented by raster models, which are convenient for processing and analysis.
