Application of Trend Surface Analysis Method in Assessment of the Geo-hazards Susceptibility-Zoning
This study presented the mathematical principle of trend surface analysis method.Based on the features of geo-hazards in Huairen,Shanxi Province,the susceptibility-zoning assessment is made by using trend surface analysis method in GIS program.The results show the consistency with the actual investigation of the geological survey information,which proves that trend surface analysis method is applicable for susceptibility-zoning assessment and can provide a new theoretical approach for geo-hazard zoning.
