基于信息量模型的滨海地区泥石流风险评价
Risk Assessment of Debris Flows in Coastal Areas Based on Information Quantity Model:Taking Debris Fows in the Mengshuiling area,Lingshui County,Hainan Province as an Example,China
摘要
Abstract
Lingshui County in Hainan Province experiences abundant rainfall with short-duration,and high-intensity.The gullies around the coastal Mengshuiling are well-developed,with steep longitudinal slopes and thick overlying layers,creating favorable conditions for debris flow development.This poses a serious threat to the Donghuan Railway,the Dongxian Expressway,the Xiangshuiwan Tourist Resort,and the marine environment below.Previous studies have primarily focused on the formation mechanisms and movement characteristics of debris flows in Mengshuiling,with limited research on the risk of debris flow occurrence.Based on an analysis of the conditions for debris flow formation in the Mengshuiling gullies,this study evaluates the debris flow risk in Gullies No.5 and No.6 of Mengshuiling using GIS technology and an information value model from the perspective of source material potential.The results indicate that Gully No.5 is largely located in a high-risk zone for geohazards,with high source material potential,a high likelihood of debris flow occurrence,and a high risk level.Gully No.6 is in a medium-risk zone for geohazards,with moderate source material potential,a moderate likelihood of debris flow occurrence,and a medium risk level.The evaluation results can provide technical references for local disaster prevention and mitigation efforts.关键词
