Ecological riverway restoration method based on riverbed structure transformation
The invention discloses an ecological riverway restoration method based on riverbed structure transformation. The method comprises a riverbed 1 and a river embankment road 5, wherein a first-stage river bank 2 and a second-stage river bank 3 are sequentially constructed from the riverbed 1 to two sides to the river embankment road 5, and the riverbed 1, the first-stage river bank 2, the second-stage river bank 3 and the natural river embankment road 5 are sequentially connected through inclined protection slopes 4; the heights of the first-stage river bank 2 and the second-stage river bank 3 are set according to hydraulic conditions of a river, aquatic plant reeds are planted on the first-stage river bank 2, xerophyte green bristlegrass and chloris virgata are planted on the second-stage river bank 3, and poplars and willows are planted on the two sides of the river embankment road 5; and a layered soil structure with alternate sandy soil and clay is constructed on a root system layer below the river bank according to the distribution of corresponding vegetation root systems. According to the method, water flow is promoted to advance, water retention, water holding and water storage performance of plant root layer soil can be achieved, and ecological restoration of a riparian zone is facilitated. The method is suitable for ecological restoration of seasonal sandy wide and shallow rivers in plain areas.
本发明公开了一种基于河床结构改造的生态河道修复方法，包括河床1、河堤路5，自河床1向两侧至河堤路5依次构筑第一级河岸2、第二级河岸3，河床1、第一级河岸2、第二级河岸3、天然河堤路5之间依次由倾斜的护坡4连接；第一级河岸2与第二级河岸3的高度根据河流的水力条件进行设置，第一级河岸2上种植有水生植物芦苇，在第二级河岸3上种植旱生植物狗尾草和虎尾草，在河堤路5两侧种植杨树和柳树。河岸下方根系层根据相应植被根系的分布构建砂土和粘土相间的层状土壤结构。该方法有利于推进水流的行进，并能实现植物根系层土壤的保水、持水、蓄水性能，有利于河岸带的生态修复。适用于平原区季节性砂质宽浅河道的生态修复。
