摘要
In the matter of geological hazards,Tanchang County is in extraordinarily severe situation in Gansu Province.Through the analysis of the data of regional geological environment,a detailed investigation of geological hazards in Tanchang County is completed by means of remote sensing interpretation and field investigation,in the manner of the combination of point,line,and area surveying.Results from the investigation show that mudslides,landslide,and collapse are the main types of geological hazards with the typical characteristics of geological hazards in loess-bedrock region.Landscape,geological structure,stratum structure,rainfall,and human engineering activity should be considered as the main formation conditions of geological hazards.
