Assessment and Research on the susceptibility of geological disasters in a certain region based on AHP and ArcGIS
The susceptibility assessment of geological hazards is a quantitative assessment of the susceptibility degree of regional geological hazards,and according to the assessment results,it can guide the prevention and control of regional geological hazards.Taking a region as an example,based on the current geological environment,AHP method is used to assign weight to the assessment factors.Collect the data related to geological hazards in the evaluation area,and assign weights to the assessment factors;The mathematical model of geological hazard susceptibility assessment was constructed by ArcGIS system,and geological hazard susceptibility zoning was carried out.The assessment results show that it is basically consistent with the current situation of the region,and provides scientific basis and prevention suggestions for local planning and construction and geological disaster prevention.
