People's demand for a beautiful living environment close to mountains and waters is rising. The treatment of urban and rural river channels has gradually developed from simple river channel excavation and filling and water environment treatment to multi-faceted and multi-angle ecological restoration of river fish habitats, so as to make the river water ecological environment more environmentally friendly, green, healthy and sustainable. The restoration degree of fish habitats is also the basis for the stability of river aquatic ecosystems and an important indicator to measure the health of urban and rural river ecosystems. At present, the constructed river bank revetments or slope protections are more for the purpose of river bank safety and landscape beautification, and simply from the perspective of hydraulic engineering, lacking consideration of the survival condition factors of river organisms, especially fish. To a certain extent, river restoration has not achieved significant effects in the ecological aquatic biological environment. Summary of the Invention
