Abstract:The researching on geo-hazards risk indicator model has been the hot spot of related departments and scholars,indicating reliability problems have always been a research difficult point and technology core.Honghe prefecture is one of the most serious areas of geo-hazards in Yunnan Province,but little research about geo-hazards risk indicator has been done in this region.Based on the information value method,a geo-hazards indicator model about Honghe prefecture was established considering the rainfall-induced factors,hazard-formative environment of this region which is the first time using 100 m× 100 m warning unit.Through the verification of historical geological hazard happening,the accuracy rate of warning can highly reach 81.8%.The result indicated that it's workable to integrate meteorological factors and geological environment factors into the indicator model which can be an effective way to improve the level of geo-hazard warning.
