摘要
Abstract
The geo-hazard comprehensive evaluation index system and evaluation models are established by using the results of geo-hazard survey.The index system consists of 2 kinds (the development degree of geohazard,the losses extent and prevention situation of geo-hazard),6 first-grade indexes,12 second-grade indexes,30 third indexes,and 100 evaluation factors.The bottom-up assessment methods are used and evaluation models are set up by factor selection,data correction,normalization processing and weight determination.Using the slope method,the evaluation results are divided into four levels to reflect the geohazards development degree,absolute or relative extent of losses and threat,distribution of types,destructive capacity and disaster situation.It is of a very important significance to improve the standard of geo-hazard monitoring and warning and to raise the level of disaster prevention and mitigation.关键词
