温州山地面积大,地形复杂,暴雨频繁,山区遍布村落民居,人类活动频繁,发生泥石流灾害或出现泥石流隐患的可能性很大。通过对温州目前存在的泥石流隐患进行分析,发现如下特征：一是相对高差小、沟床比降大、流域面积小、流域形态独特、两侧山体坡度大;二是大部分泥石流发育在风化强烈的熔结凝灰岩、玻屑凝灰岩、沉积相凝灰质砂岩、沉凝灰岩和侵入岩中;三是多数泥石流多分布在断裂交汇处,其形态与地质构造、地貌格局相一致,主要呈北东向带状分布;四是温州大部分泥石流属于低易发,但是危害大,具有群发性、低频性、猛烈性等活动特征。本文初步总结了温州泥石流的特征,为泥石流治理提供依据。

Wenzhou has the vast area of mountain,as its terrain is complex and has frequent rain storm;villagers are throughout its mountainous area where human activities are frequent,which makes Wenzhou has a high possibility of happening debris flow.By analysis of Wenzhou current existing debris flow hazard,the main characteristics of debris flow were found in four aspects.Firstly,the debris flows generally have a small relative elevation,large ditch bed gradient,small catchment area with special watershed morphology,heavy slope of the mountain both sides.Secondly,the majority of debris flow are developed in strong weathered ignimbrite,vitric tuff,sedimentary tuffaceous sandstone,sedimentary tuff and intrusive rock.Third,the majority of debris flow are distributed in the intersections of sets of fractures,its form is in compliance with geologic structure and morphological pattern,mainly showing northwest zonal distribution.Fourth,The majority of debris flow in Wenzhou is low disaster-prone but with great harm,often with simultaneous occurrence,Low frequency,violent,etc.The writer tries to sum up the characteristics of Wenzhou debris flow,which provides the basis for management engineering.
