Embodiment 1

[0046] Such as Figure 1 to Figure 5 As shown, a kind of riverbed structure ecological reconstruction method for high seepage seasonal rivers provided by the application adopts the following technical scheme:

[0047] In the first aspect, the present application provides a method for ecological transformation of the geometric structure of the cross-section of the river to restore the ecological environment of the river, and adopts the following technical scheme:

[0048] The invention relates to an ecological reconstruction method for the geometrical structure of the cross-section of the river channel for restoring the ecological environment of the river channel, which includes a river bed, a first-level river bank, a second-level river bank, an inclined slope protection, and a river embankment road. When the water flow is very small, it only travels on the riverbed, and when the water flow is slightly larger, it will overflow the lower first-level river bank, and when the wat...

Abstract

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.

Description

technical field [0001] The invention relates to a river ecological restoration technology, in particular to an ecological river restoration method based on river bed structure transformation. Background technique [0002] The river ecosystem has multiple functions such as water delivery and landscape. With the general reduction of runoff, the river has been dry and dry for a long time, the river bed is exposed, and the ecological environment of the river and the riparian zone has been seriously degraded. Especially in the plain area, the river channel formed by alluvial and flood deposits is higher than the ground, with artificial embankments on both sides. The river channel has the typical characteristics of wide, shallow, sandy and high seepage, and the river presents seasonal and transient characteristics. , the time for water delivery is short, the flow is large, and floods are prone to occur. In addition, there is a groundwater "funnel" phenomenon, the river is out of...
