摘要
通过构建地质灾害发育强度指数和降雨强度指数,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3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。
Through building the instensity index of geo-hazard development and rainfall and the evaluation model for Geo-Hazard susceptibility of rainfall , the province were classifiled into the higher, the general and the lower level of 3 types. With ArcGis platform and the raster data model to evaluate the geographical distribution and Conduct in depth analysis of space and processing.
