Discussion on the development characteristics and formation conditions of geological hazards in Yongren County,Yunnan Province
This paper takes Yongren County,which is located in the north central Yunnan Province,as the research object.Through data collection,remote sensing survey,ground survey,and comprehensive research methods,the development characteristics of geological disasters in the study area are summarized and analyzed,and the formation conditions are explored according to their development characteristics.Research shows that there are three main types of geological disasters in the area:landslides,collapses,and mudslides,with landslides and mudslides being the main types,followed by collapses.There are a total of 111 geological hazard points in the entire region,mainly small and medium-sized.The geological disasters in this area are formed under the influence of various factors such as topography,geological structure,stratigraphic lithology,rock and soil structure type,rainfall,earthquake,and human activities.Among them,topography,geological structure,stratigraphic lithol-ogy,and rock and soil structure type are the main factors causing the formation of geological disasters,while rainfall,earthquake,and human activities are the inducing factors for the formation of geological disasters.Finally,this paper believes that geological conditions have the greatest impact on the formation of disasters,fol-lowed by rainfall factors and finally human activity factors.Based on the types,development characteristics,and distribution patterns of geological disasters,we should adjust measures to local conditions,strengthen monitoring and prediction,and carry out geological disaster prevention and control work well.
