河岸带植被重建的生态修复技术及应用

Technology and Application for Ecology Rehabilitation on Riparian Vegetation Restoration

以上海市崇明生态岛的杜鹃河坡岸示范工程为例,探讨了以生态修复和稳定坡岸为目标的植物护岸技术在城镇生态型河道坡岸修复中的应用。在不同河段分别采用了全系列生态护岸、土壤生物工程护岸和复合式生物稳定等3类植物护岸技术;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,在生态型河道中采用植物护岸技术可以稳定坡岸、改善坡岸的栖息地质量、修复河道的生态环境。生态型河道的植物护岸技术可以在我国各类岸坡的生态修复和边坡稳定中广泛运用。

We took the Dujuan River in Chongming ecological island,Shanghai as an example to study the practice and its ecological effect on plant slope protection techniques of streams,which could provide an effective means for the slope stabilization and site restoration of stream bank.We investigated the application of three kinds of plant slope protection techniques,including all-series vegetated protection,soil bioengineering,and combined biostabilization at different sites of ecological river.After 10-month project implementation,significant effectiveness was obtained on slope stability,habitat improvement,and ecological restoration of stream banks.It was concluded that the approach could be widely applied in ecological restoration and riverbank stabilization of all kind of slopes in China.
