青藏高原东部典型高位泥石流灾害成因机制与研究展望
Formation mechanism and research prospect of typical high-altitude debris flow disasters in the eastern Tibetan Plateau
摘要
Abstract
The high-altitude geological hazards along the eastern Tibetan Plateau has a rising occurrence due to global climate change.Among these,high-altitude debris flows stand out due to their unique traits,including larger magnitudes,greater concealment,longer travel distances,and more devastating impacts compared to con-ventional debris flows.Based on recent global and domestic research,the conceptual definitions,classifications,disaster mechanisms,formation processes,and kinematic features of high-altitude debris flows in this area were comprehensively reviewed in this study.Four dominant disaster-triggering modes were identified,that is rainfall-induced high-altitude debris flows,glacier-ice-rock collapse debris flows,rainfall and snowmelt wa-ter-induced debris flows,and glacial lake outburst debris flows.And the authors conducted a study on the causes and potential risks by taking high-altitude debris flows in three regions as typical cases,revealing the huge risks,hazardness and destructiveness of the high-altitude debris flows in the eastern Tibetan Plateau.On this basis,three research prospects for high-altitude debris flow were proposed,and relevant theorits and methods that can be used for reference in the study of high-altitude debris flows in the eastern Tibetan Plateau were pointed out.Be-sides,the research ideas on equipment development,early warning systems establishment and dynamic evolution models for high-altitude debris flows were also discussed.关键词
