大型输水渠道渠岸带植物配置模式研究

Research on Models of Plant Arrangement of Eco-embankment Zones in South-North Water Transfer East Route Channel

为解决大型渠道施工中所形成的大面积次生裸地引起的水土流失问题和渠道沿线生产生活垃圾对渠道水质造成的污染问题,有效保障渠道输水质量,实现南水北调工程"清水长廊"的总体目标,提出了生态渠岸带的概念和设计原则。在此基础上,以南水北调工程东线为例,根据治理渠道岸坡水土流失、消滞农田面源污染和绿化美化沿线环境等不同目标,将渠岸带分为非过水断面、堤顶公路、防护堤和缓冲带四个区域,进行其植物配置模式研究,从而形成点线面相结合的渠岸带绿化景观格局,为生态渠岸带的建设提供参考。

In order to solve the soil erosion of large area secondary bare area and pollution of water channels by garbage caused by production and living, guarantee water transfer diversion, attain the goal of ＂clean water way＂ in South-North Water Transfer Pro- ject, this paper presents the conception and design principles. On this basis, according to the goals of controlling the soil erosion in channel banks, reducing the pollution from farmland non-point source pollution and greening the environment, it analyzes the models of plant arrangement of eco-embankment zones in non-cross-section, roads, embankment and the buffer zonesand serves as a reference for the construction of coo-embankment zone.
