【摘要】 以广东潮州—揭阳地区为例,在分析泥石流形成条件的基础上,针对其来源提出了"隐形松散堆积物"的概念,并分析了物源的形成过程和机理,重点探讨了台风暴雨与植被以及人类活动对泥石流的影响,认为它们是潮揭泥石流物源形成的重要原因,从而改变了长期以来认为该地区泥石流松散固体物质缺乏的认识,为该类地区泥石流研究提供了一个突破口。更多还原

【Abstract】 Taken the Chaozhou and Jieyang area in Guangdong province as an example and based on the analysis of the formation condition of the debris flow,this paper proposes the concept of the potential incompact solid matter and analyzes the formation condition and mechanism of substance source.In particular,this paper discusses the influence of torrential rain,vegetation and human activities to the debris flow.They are the important factors causing the formation of the debris flow source.The viewpoint that solid matter is shortage in this area can be changed.The research results provide a breach for the debris flow research in this area.更多还原
