A SINMAP-Based Quantitative Assessment and Model Verification of Regional Landslide Hazard

The regional landslide hazard is evaluated by the factors that affect the stability of the landslope,therefore,the regional landslide hazard evaluation is the landslope stability evaluation.In this paper,Lueyang County,Shaanxi Province is selected as the study area,where the landslide develops typically.By using the quantitative distributed model SINMAP that studies the hillslope stability and 3S(GIS,RS,GPS) technique,the comparison of analogue modeling findings with the most authoritative results of landslide hazard investigation of Chinese cities and counties finds that there are a lot of similarities on the qualitative landslide evaluation,the division of landslide hazard zonation and the criterion of division.It shows that the results of analogue modeling are reliable,and the landslide hazard of the study area are objective,and can give a relative accurate prediction of the potential landslide.Therefore,SINMAP provides a solid foundation for the quantitative analysis of the relationship between study area landslide and the environmental factors and the prediction of the regional landslide.
