济平干渠堤岸带植物修复技术

Study on embankment phytoremediation technology in Ji-ping Channel

为解决大型渠道施工中形成的大面积次生裸地的水土流失问题,减少边界污染物对渠道水质的影响,提出了渠道堤岸带植物修复原则。在此基础上,以济平干渠为例,按照修复目标将研究区域分为植物护坡区、植物防护绿篱和植物削污滞污区3个区域,进行植物配置研究,形成点、线、面相结合的绿化景观格局。在治理水土流失和削污滞污的同时,绿化美化沿线环境,实现"清水长廊"的目标和渠道的可持续发展。

In order to solve the soil and water loss of a large bare area that is part of ongoing large canal construction as well as the effect of boundary poUufion on water quality, the design principles of embankment phytorernediafion are presented. On this basis, using the Ji-Ping Channd as an example, and according to reparation goals, the study area was divided into three regions： a plant slope protection region, a plant hedge, and a diminished and laged contamination region. The plant disposition study was conducted, and a green landscape pattern of combined spots, lines and faces developed. The soil and water loss and the diminished and laged contamination were controlled. Meanwhile, the environment of the channel was beautified. The objectives of creating a clean waterway and sustainable development in the channel were achieved.
