摘　　要：基于国内外研究现状,对漂木的补给、搬运堆积、聚集堵塞、溃决等动力过程进行了详细评述,总结出山洪泥石流中漂木致灾效应包括冲击破坏、堵塞淹没、堵塞冲刷、溃决冲刷4个方面,并着重阐述了现有研究的不足。为应对漂木致灾效应,提出工程措施与管理措施相结合的漂木防灾减灾措施。在此基础上,指出未来研究的主题包括:漂木补给定量评估、漂木运动停积堵塞溃决动力过程、漂木致灾效应与风险评估、漂木灾害调控与减灾措施。Based on the research status,the dynamic processes of drift wood recruitment,transport-accumulation,accumulation-blockage and breakage were reviewed in detail,and the disaster effects of drift wood in flash flood and debris flow were summarized from four aspects of direct impact damage,clogging-submergence,clogging-scouring,and breakage-scouring.In order to deal with the disaster effect of drift wood,the disaster prevention and mitigation measures combined with engineering measures and management measures were put forward.On this basis,it is pointed out that the future research topics on drift wood disaster include quantitative evaluation of drift wood recruitment,dynamic process of drift wood transport-accumulation-clogging-breakage,disaster-causing effect and risk assessment of drift wood,disaster control and mitigation measures of drift wood.
