通南高沙土区河道岸坡生态治理模式研究

Study of Ecological Restoration Models of River Bank in Jiangsu Tongnan Area of Soil with High-content Sands

针对通南高沙土区河道水土流失及其硬质化治理引起的生态环境问题,提出从生态修复的角度对河道岸坡采取生态治理的思路.针对硬质化岸坡的生态修复,提出了包括植被岸坡覆盖技术、种植池式垂直绿化驳岸修复技术、景观净污型混凝土组合砌块护岸、活枝捆生态挡土墙垂直驳岸技术、坡面打洞及回填技术等多种方案;针对自然河道岸坡的生态整治,提出了包括植物护岸、木桩植被复合护岸、石笼净水复合护岸、生态袋护岸、植物工程复合护岸等多种方案;并对各种方案的特点、优缺点及其适用类型进行了对比分析,为通南高沙土区河道的生态治理技术选择提供参考依据.

As the serious soil erosion, Jiangsu Tongnan area of soil with high-content sands has being treated as an important area of sol caused to serious ecologica and water conservation. Soil erosion and concreting of river bank in this area have and environmental problems. This paper discusses the countermeasures from the viewpoint of ecological restoration. Five kinds of technologies are recommended to restore bank. Eleven kinds of technologies are recommended to restore the natural river bank of characteristics, advantages and disadvantages of these technologies are comparatively suggestions for ecological restoration models of river bank in this area are presented.
