Geological disaster risk assessment based on ecological niche model: A case study of Longhui County, Shaoyang City

Geological disaster risk assessment is crucial for the prevention and control of geological disasters. This study focuses on the significant number of geological disasters induced by urbanization construction in Longhui County, aiming to propose effective preventive and control measures. The study considered various disaster-inducing factors and selected 13 assessment criteria from topography and geomorphology, geological structure, engineering geology of geotechnical bodies, and human engineering activities. The MaxEnt model is employed to establish the geological disaster hazard assessment model, while 7 assessment factors are selected from population distribution, economic background, environmental resources development, disaster prevention, and mitigation capacity. The systematic cluster analysis model was then utilized to establish a geological disaster vulnerability assessment model. The results of both assessments were integrated to construct a comprehensive geological disaster risk assessment model fo
