通过对河南省66个县（市）地质灾害调查与区划等相关地质灾害资料分析，认为全省地质灾害类型为滑坡、崩塌、泥石流、地面塌陷、地裂缝、地面沉降，地质灾害具有地域性强、分布集中、一灾为主，多灾并发的特征。采用地质灾害危险度、威胁人数和潜在财产损失来组成地质灾害险情评价模型，将河南省全省划分为6680个单元，在单元险情评价的基础上进行全省地质灾害险情评估，将全省地质灾害险情划分为：险情特大区、险情大区、险情中区、险情小区和险情轻微区。

According to analysis on relevant geological hazard data of geological disaster survey and regional-ization in 66 counties (cities)in Henan province,geological hazard types in the province are considered as land-slide,collapse,mud dock flow,surface collapse,ground crack and ground subsidence.The hazards are featured in strong regionalization,concentrated distribution,centering round one hazard and development with more hazard. An evaluation model for geologic disaster danger is established based on degree of geological hazard danger,number of people could be threatened and potential economic losses.Henan Province is divided into 6680 units.Based on the dangerous condition evaluation of the units,the geological hazard dangerous condition is evaluated in Henan Province and the geological hazard dangerous conditions there are divided into 5 types as extra large dangerous con-dition zone,large dangerous condition zone,medium dangerous condition zone,small dangerous condition zone and slight dangerous condition zone.
