Description

Technical Field

[0001] This utility model relates to the field of water ecological restoration technology, specifically to an ecological restoration system for habitats in the buffer zone of a reservoir-river bay. Background Technology

[0002] The existing reservoir-river bay buffer zone has low biodiversity and its habitat has been destroyed. Because the reservoir-river bay buffer zone is wide, the water flow is slow, silt is left in the buffer zone, the water quality cannot be purified, the river's biological habitats are monotonous, and the ecological diversity is severely damaged. At the same time, due to the low water volume of urban rivers, the water quality is prone to decay and pollution. The reservoir-river bay buffer zone also serves urban functions such as flood discharge, which can easily cause devastating damage to the river's ecology.

[0003] Therefore, there is a need to provide an ecological restoration system for the habitat in the Kuhe Bay buffer zone to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an ecological restoration system for the habitat of the Kuhewan buffer zone, which can effectively improve the biodiversity of the Kuhewan buffer zone, restore habitat, prevent rainstorm disasters, and reduce flood peak.

A riverbed is provided on the side of the river embankment closer to the center of the reservoir-river bay. Multiple dams are provided on the riverbed and on the other side of the river embankment closer to the center of the reservoir-river bay. Floating beds are provided in the riverbed and downstream of the dams. Aquatic plants are planted around the riverbed and the dams.

[0007] As a further improvement to the above technical solution, the floating bed includes a first floating bed and a second floating bed, wherein the first floating bed is disposed in the riverbed and the second floating bed is disposed downstream of the dam.

[0008] As a further improvement to the above technical solution, the riverbed includes a mother riverbed and a daughter riverbed, and the height of the mother riverbed is higher than the height of the daughter riverbed.

[0019] Reference Figure 1An ecological restoration system for a reservoir-river bay buffer zone includes a reservoir-river bay 1 and a river embankment 2. The river embankment 2 is located on both sides of the reservoir-river bay 1 to prevent flooding and protect the riverside area from flooding. A riverbed 3 is provided on the side of the river embankment 2 closest to the center of the reservoir-river bay 1. Multiple dams 4 are provided on both the riverbed 3 and the other side of the river embankment 2 closest to the center of the reservoir-river bay 1. The multiple dams 4 are relatively staggered to regulate the water flow speed and also play a role in flood storage during floods. Floating beds 5 are provided in the riverbed 3 and downstream of the dams 4. The floating beds 5 provide habitats and breeding grounds for aquatic organisms. Aquatic plants are planted around the riverbed 3 and the dams 4. The whole system forms a multi-layered and comprehensive ecological restoration system, which not only beautifies the environment but also enhances the self-repair capacity of the ecosystem, provides habitats for organisms, and promotes biodiversity.

[0020] Reference Figure 1 In an embodiment of this utility model, the floating bed 5 includes a first floating bed 51 and a second floating bed 52. A still water area is set in the riverbed 3, and the water near the dam 4 is flowing water. The first floating bed 51 is set in the riverbed 3, and the second floating bed 52 is set downstream of the dam 4, providing more precise ecological support for the water flow conditions and aquatic organism needs of different areas.

[0021] Reference Figure 1 In an embodiment of this utility model, the riverbed 3 includes a mother riverbed and a daughter riverbed, and the height of the mother riverbed is higher than that of the daughter riverbed. Normally, the daughter riverbed is used for drainage, while the mother riverbed is left idle. The mother riverbed is paved with pebbles, which helps to regulate the water flow speed, reduce the scouring of the riverbanks by the water flow, and increase the retention time of the water body, which is conducive to the habitat and reproduction of aquatic organisms.

[0022] The sub-riverbed is concave and has multiple still water zones 6. The first floating bed 51 is set in the still water zone 6. The still water zone 6 provides a relatively quiet and slow-flowing living environment for aquatic organisms, which helps to improve biodiversity.

[0023] The river dam 4 is constructed of pebbles, which creates a rapid flow zone after the river water passes through multiple dams 4, increasing the water flow speed, reducing silt accumulation, and improving water quality. The river dam 4 is located on the side of the sub-riverbed near the center of the reservoir bend 1, and is located between two adjacent still water zones 6. This allows the river dam 4 to control the water flow towards the center of the reservoir bend 1, providing a relatively quiet and slow-flowing living environment for the still water zone 6, increasing the complexity and biodiversity of the water body.

[0024] The river dam 4 on the side of the riverbank 2 is staggered relative to the river dam 4 on the side of the sub-riverbed, which can more effectively regulate the water flow, reduce the direct impact of the water flow on the riverbank, reduce silt accumulation, and help improve water quality.

[0025] In addition, a buffer zone 7 is set up upstream of the dam 4. The buffer zone 7 is close to the dam 4 and the riverbank 2 or the riverbed 3, forming a triangular structure, which helps to regulate the water flow speed. At the same time, the buffer zone 7 also provides habitats and breeding grounds for aquatic organisms, increasing the diversity of the ecosystem. The buffer zone 7 is paved with pebbles and soil, with the soil placed on top of the pebbles, and aquatic plants are planted on the soil to further improve water quality through the absorption and degradation of aquatic plants.

[0026] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
