Siltation promotion device and natural coastline generation method

The invention provides a siltation promotion device and a natural coastline generation method, and relates to the technical field of coastal zone regulation remediation technologies. The siltation promotion device provided by the invention comprises first bank strengthening assemblies and a first culture medium; the first bank strengthening assemblies are connected with the first culture medium and are used for adsorbing reef-building organisms; and the first culture medium is used for breeding algae. Through the siltation promotion device provided by the invention, the technical problem thatecological siltation promotion underwater construction is difficult to conduct is solved, the reef-building organisms can diffuse and grow on the first bank strengthening assemblies, an organic reef body is formed, water flow resistance can be increased, silt deposition is facilitated, and a matrix and nutriment are provided for the algae; the algae and the organic reef body act together, thus, the water flow resistance c
