River bank ecological restoration device and restoration method suitable for characteristics of mountain river

Abstract

The invention discloses a river bank ecological restoration device suitable for characteristics of a mountain river in the technical field of river bank ecological restoration. The river bank ecological restoration device suitable for the characteristics of the mountain river comprises vertical columns arranged on a slope surface of a river bank, wherein the vertical columns are arranged in multiple layers from top to bottom along the slope surface, a stone blocking rope net is connected between every two adjacent vertical columns in the same layer, gravel protection feet are piled on the lower sides of the vertical columns on the lowermost layer, gravel foundation layers are piled between the vertically adjacent stone blocking rope nets, soil layers are laid on the tops of the gravel foundation layers and the gravel protection feet, waterfront plant layers are planted on the soil layers, hygrophyte layers are planted on the gravel protection feet and a river channel surface, herbaceous plants and arbors are planted on the upper part of the river bank. According to the river bank ecological restoration device suitable for the characteristics of the mountain river, the mode that the vertical columns and the stone blocking rope nets are combined is adopted, and the gravel foundation layers are intercepted and placed; compared with the mode that a gabion is adopted in the prior art, the use environment is more flexible, operation is easier, and the river bank ecological restoration device is especially suitable for the conditions that the mountain river bank is large in curvature and too many in bends.

Description

technical field [0001] The invention relates to the technical field of river bank ecological restoration, in particular to a river bank ecological restoration device and restoration method suitable for the characteristics of rivers in mountainous areas. Background technique [0002] The riparian zone refers to the river bed between the high and low water levels of the river and the area above the high water level until the influence of the river water completely disappears, including the non-permanently submerged river bed and the floodplain area above it. The riparian zone is an interlaced zone of land and water, which has obvious edge effects, plays a significant role in ecosystems and landscapes, and is characterized by ecological fragility, biodiversity, periodic changes, and frequent human activities. The riparian zone of mountainous rivers is an ecological transition zone between rivers and highland vegetation. Due to the temporal and spatial unevenness of rainfall in ...

Problems solved by technology

[0005] Although the above-mentioned device has the function of stabilizing the river bank and providing a porous habitat for microorganisms and aquatic organisms, and is cheap and easy to operate, but the river bank in some mountainous areas has a large degree of curvature and many bends, and it is difficult to make the gabions stacked neatly and efficiently by using gabions. The stacking process is more troublesome, which increases the difficulty of ecological restoration of rivers in mountainous areas
