摘　　要：白龙江中游千枚岩出露区泥石流分布集中、暴发频繁、灾害严重,生态修复难度大。分别从该区社会经济、气候、地质角度阐述了泥石流生态修复的难点;从水土互相作用与泥石流流体结构、土体与土体结构、沟谷地貌、坡面形态、泥石流沟流域形态揭示了泥石流发育机制,以及植被在其中的作用机制。分析了传统水平台型整地与竹樊保持水土技术、植苗与微圃植树法造林技术、传统造林树种选择与生态公益植被物种选择技术、常规混交造林与毒—刺混交植被植物种类配置模式等4组基本技术的优缺点及其适用范围,分别确定了生态公益植被与经济利用植被的营建技术。最后,根据研究区地貌分异特点和当地社会经济状况,将泥石流沟分为清水区、泥石流形成区、经济利用区、道路工程影响区4个功能单元,分别论述生态修复技术,有机结合新技术与传统技术集成为泥石流生态修复技术体系。In middle reaches of Bailong River,debris flow on bare phyllite outcrop is distributed concentrative,occurred frequently,disasters seriously,and difficult to repair.The article summarized the difficulty of ecological restoration from social economy,climate,geological point of view in this area.Reveals the mechanism of debris flow development,and the mechanism of action of vegetation from the interaction between soil and water conservation and soil structure,soil and debris flow fluid structure,vale landform,slope,debris flow gully watershed.Analyzed the advantages and disadvantages of four groups of basic technology and its applicable scope,the four technology are traditional soil preparation,technique on bamboo hedge delay spread of runoff,micro-nursery and traditional forestation tree species selection and vegetation species selection techniques of ecological commonweal,conventional mixed forestation and poison-mixed vegetation species configuration mode,respectively determined the construction technology of the ecological public vegetation and economic use of vegetation.The last,The debris flow gully is divided into four functional units（clear water area,the debris flow formation area,economic use of area,road engineering influence area） based on the characteristics of morphological differentiation in the study area and the local social and economic conditions,the paper discussed the respectively ecological restoration technology,combined with the new technology and traditional technology for ecological restoration technology of debris flow.
