Abstract

The invention provides a riverway ecological restoration system and restoration method, and belongs to the technical field of riverway restoration. The riverway ecological restoration system comprisesa riverway, the riverway comprises shoals and deep pools, the shoals comprise slow flow shoals and rapid flow shoals, a spur dike (1) is arranged at each rapid flow shoal, a bottom protection fixinggroove (2) is arranged at each deep pool, and aquatic plants (3) are planted at the slow flow shoals. According to the riverway ecological restoration system, by changing the waterpower condition of the riverway, the topographic characteristic that deep pools and shoals are alternated is formed, animals can inhabit conveniently, a healthy food chain of the river can be constructed, a riverway foodnet is formed, and the biodiversity of the riverway and the surroundings is enriched. The restoration method of the riverway adopts an ecological means, so that the ecological system of the riverwayis kept in a balanced state, the biodiversity is maintained, and the method is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of river course restoration, and in particular relates to a river course ecological restoration system and restoration method. Background technique [0002] A river course is a complex ecosystem including land, animals, plants, and water bodies. It has the functions of regulating runoff, regulating water volume, removing toxic and harmful substances in water, and providing habitats for aquatic and terrestrial animals. The characteristics of vegetation are obviously different from those of the land on both sides. High levels of species diversity. At present, river restoration projects in my country mostly consider the water conservancy conditions of the river. The common river regulation projects are as follows: 1. Heighten the embankment; 2. Use reinforced concrete and block stone structures; 3. Artificialize and channelize the river course; However, the adoption of the above methods will greatly affect the...
