River channel structure capable of ecologically preparing river flowing into lake in lake basins

Abstract

The invention belongs to the field of ecological repairing of water environments in lake basins and particularly relates to a river channel structure capable of ecologically repairing a river flowing into a lake in lake basins. The river channel structure comprises a river channel base, a river channel bank slope and river channel buffering belts. A layer of vegetation form ecological blanket is laid on the river channel base. Aquatic plants are planted on a river channel bank slope. The river channel bank slope comprises a river channel revetment and a river channel land area side bank, wherein the river channel revetment is a step type revetment and sequentially comprises a first-step ecological embankment, a second-step ecological embankment, a third-step ecological embankment, a fourth-step ecological embankment and a fifth-step ecological embankment from bottom to top. Terrestrial plants and herbaceous plants which are reasonably matched are planted on the river channel buffering belts, and the river channel buffering belts include the first buffering belt, the second buffering belt and the third buffering belt. The river channel structure is simple in structure and low in construction cost, the ecological environment of the river flowing into the lake in the lake basins can be repaired, the water quality of the river is improved, the ecological system of the river is recovered, and the self-cleaning capability of the river is improved.

Description

technical field [0001] The invention belongs to the field of ecological restoration of the water environment in lake basins, and in particular relates to a channel structure capable of ecological restoration of lake-flowing rivers in lake basins. Background technique [0002] Because people pay more attention to economic development but ignore the protection of the environment, environmental problems are becoming more and more prominent. As a link between land and lakes or oceans, rivers are increasingly polluted. The environmental problems of the river course are mainly manifested in the following aspects: 1) water and soil erosion, etc. cause the river channel to be blocked and silted, and the flood control capacity is reduced; Substances, heavy metals, etc., under certain conditions, they will dissolve from the sediment and re-enter the water body to form a pollution source, which will cause a sharp decrease in the species of aquatic plants, animals, and microorganisms i...

Problems solved by technology

The environmental problems of the river course are mainly manifested in the following aspects: 1) water and soil erosion, etc. cause the river channel to be blocked and silted, and the flood control capacity is reduced; Substances, heavy metals, etc., under certain conditions, they will dissolve from the sediment and re-enter the water body to form a pollution source, which will cause a sharp decrease in the species of aquatic plants, animals, and microorganisms in the water body, and the vicious cycle of the river ecosystem will greatly reduce the self-purification ability of the river. Polluted water bodies are not purified
