Abstract

The invention relates to a method for recovering the vegetation diversity of a river channel. The method comprises the following steps of surveying geographic conditions and hydrologic conditions, surveying local aquatic plants, screening the aquatic plants, improving substrates at a river bottom, planting the aquatic plants and performing follow-up management on the planted aquatic plants. In addition, the invention further discloses a multi-layer natural material river bed. Besides, the multi-layer natural material river bed is adopted in the step of improving the substrates at the river bottom in the method for recovering the vegetation diversity of the river channel. According to the scheme disclosed by the invention, the bottom substrates at the river channel of an urban inland river with ecosystem degradation are improved, the local aquatic plants with high climate adaptability and prominent dirt removing capacity are in optimal configuration, the vegetation of the river channel of the urban inland river is specifically recovered and rebuilt, the biological diversity in the river channel is rapidly and effectively improved, and water quality is purified.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration engineering, and in particular relates to a method for restoring river channel vegetation diversity and a multi-layer natural material river bed. Background technique [0002] A river is a complex system composed of terrestrial riparian aquatic systems, aquatic ecosystems, wetlands and swamp ecosystems. The urban inland river passing through the city once assumed the important functions of water supply and transportation. At the same time, the two sides of the urban inland river can often become natural and cultural landscapes with local characteristics. With the improvement of people's ability to transform nature, the importance of river transportation has been declining, and the massive exploitation of groundwater has also reduced the status of the core water source of the river. With the development of industry and the further expansion of cities, the original features of river l...
