生态河道的坡岸绿化技术探索与应用

Exploration and Practice of Riverbank Green-planting Techniques on Ecological Rivers

河道生态系统中的河岸侵蚀和滨水缓冲带建设备受关注。以上海市浦东新区机场镇的生态河道示范工程为例,介绍了以生态修复和稳定坡岸为目标的河道生态护坡技术。在不同河段分别采用了全系列生态护坡、土壤生物工程护坡和复合式生物稳定3类生态护坡技术:对比了工程实施后河道坡岸10个月来的坡岸土壤剪切力、生境条件和生物多样性变化。研究和示范工程表明,采用河道生态护坡技术可以稳定坡岸、改善坡岸的栖息地质量、修复河道的生态环境。生态河道的坡岸绿化技术可以在我国各类岸坡的生态修复和边坡绿化中广泛运用。

The erosion of riverbank and the disappearance of riparian buffering strips are among Ihe concerns in river ecosystem In this study, an eirport town in Pudong New Dislrich Shonghgi was taken as an example to study ecological slope prolection.techniques of streams,which could provide an effective means for the slope stabilization and site restoration of stream bank. The application of three ecological slope protection techniques, including all-series vegetated protection, soil bioengineering, and combined biostabilization at different sites of ecological nver, were investigated After 10-month project implementation, significant effectiveness was obtoined on slope stability, hobitat improvement, and ecological restoralion of stream bank. It was concluded that the approach could be widely applied in ecologlcal restoralion and riverbank green planting of all kind of slopes in China.
