摘　　要：新时期生态河道工程对低碳、生态材料的需求巨大。基于植物纤维材料已有的研究成果、文献和国内外工程实践案例,该研究分析了植物纤维材料的水利生态功能和水利结构功能,探讨了河道断面设计和施工工艺方面的注意事项。植物纤维毯主要用于河道岸坡完工初期,发挥其保持水土作用,纤维-土壤综合体的形成使得水土保持作用具有一定的持续性。纤维材料通过水土保持、改良土壤、促进植被恢复等作用,促进岸坡生境系统发展。植物纤维材料的形状特征和工作环境,决定了其水利结构功能,具体包括生态护坡、水景观(生态围堰与生态岛)、岸坡护脚和河床护底等。植物纤维毯主要用于土壤能够达到自身稳定的岸坡,其抗冲流速不大于3.0 m/s。植物纤维毯作为一种柔性材料,施工简单方便,多与其他措施配合应用,设计和施工中应注意植物纤维材料功能的时空变化。The ecological river course project in the new period has a great demand for low carbon and ecological materials.Based on the existing research results of plant fiber materials,engineering practice cases and existing literature all over the world,this work analyzed the ecological function of water conservancy and water conservancy structure function of plant fiber materials,and discussed the points for attention in river section design and construction technology.Plant fiber blanket is mainly used in the initial stage of river bank slope completion to play its role of water and soil conservation.The formation of fiber-soil complex makes the role of water and soil conservation have a certain continuity.Through soil and water conservation,soil improvement and vegetation restoration,the development of habitat system on bank slope is promoted.The shape characteristics and working environment of plant fiber materials determine the function of water conservancy structure,including ecological slope protection,water landscape(ecological cofferdam and ecological island),bank slope foot protection and river bed bottom protection,etc.Plant fiber blanket is mainly used in the bank slope where the soil reaches its own stability,and its anti-impact velocity is no more than 3.0 m/s.As a kind of flexible material,plant fiber blanket is simple and convenient in construction.It is often used with other measures.Attention should be paid to the temporal and spatial changes of plant fiber material function in design and construction.
