基于模糊层次分析的房山区五丰沟泥石流危险性评价
Risk assessment of debris flow in Wufenggou,Fangshan District based on fuzzy analytic hierarchy process
摘要
Abstract
In July 2023,heavy rainfall triggered multiple landslides and collapses in Wufeng Gully,Fangshan District,leading to a substantial accumulation of loose material in the gully.Combined with the effects of human activity,this has significantly elevated the debris flow risk,posing a serious threat to downstream residents and infrastructure.This study focuses on the Wufeng Gully debris flow.Based on field investigations and an analysis of the regional geological background,formation conditions,and developmental characteristics,a nine-indicator evaluation system was established,encompassing geological,topographic,and hydrodynamic factors.The fuzzy analytic hierarchy process(FAHP)was used to evaluate the debris flow hazard.The results indicate that the debris flow in Wufeng Gully has reached a highly dangerous state,a finding consistent with field observations.This study provides a scientific basis for disaster prevention and mitigation strategies in the area.关键词
