Study on the Evaluation Method of Geological Disaster Susceptibility in the Southeast Coastal Area of Fujian Province
The aim of this study is to explore the evaluation method of geological hazard susceptibility in the southeastern coastal area of Fujian,with the aim of providing scientific basis for the prevention and control of ge-ological hazards in the region.The method of dividing cells and combining entropy method are used to quantita-tively analyze key influencing factors such as terrain slope,rock hardness,vegetation coverage,annual precipitati-on,and geological activity.The research area includes the surrounding areas of Fuzhou,Quanzhou,and Xiamen.Based on the collected geographical and geological data,a comprehensive evaluation was conducted by establis-hing a weight system.The results showed that the geological hazard susceptibility scores of each evaluation unit were different,among which the average terrain slope of Fuzhou is 25°,Quanzhou is 35°,Xiamen is 15°,and the annual precipitation is 1500,2000,1200 mm,respectively.Based on this,specific geological disaster prevention measures have been formulated.The research conclusion indicates that this evaluation method can effectively i-dentify high-risk areas,providing accurate data support and theoretical basis for local governments and relevant institutions to formulate targeted geological disaster prevention and control strategies.
