The present invention relates to multifunctional artificial reefs for marine ecosystem restoration, A reef sphere having a polygonal horn shape inclined from the bottom of the reef to the top part, a large side fish moving passage formed with moving passages of fish on each side and top and bottom of the reef sphere, a small side fish moving passage, and a vertical fish moving passage And a fish habitat space part in which the fish are freely typed in the inside of the reef sphere and form a habitat, spawning and avoiding space to form a nest of fish, and a marine plant on the top, the side, and the bottom of the reef sphere. Uneven parts for easy habitating and growth of marine plants by providing a smooth space for easy spore implantation and stable root immobilization of plants, and are installed at the bottom of the large lateral fish passage, octopus, squid, octopus Multifunctional composite artificial reef for marine ecosystem restoration comprising a marine small animal habitat comprising a growth space for molluscs, such as Bars, In the artificial reefs, a vertical fish movement passage penetrating the sphere in the form of a circular column in the center, a vertical fish movement passage penetrating the four surfaces of the bottom of the fish sphere, and four of eight surfaces of the fish sphere are opened to free the movement of the fish. Large lateral fish migration passage, hollow structure inside the reef sphere, a fish habitat part that provides a space for growth, habitat and spawning, easy spore implantation of marine plants on the side of the reef sphere, stable roots of plants Alternative to artificial reefs, consisting of uneven parts to facilitate the habitat and growth of marine plants by providing a smooth space for achieving immobilization, The artificial fish weighing apparatus according to any one of claims 1 to 3, wherein the artificial fish candle has a triangular hollow structure, Which is an irregular part for facilitating the habitat and growth of marine plants by providing a smooth space for stabilizing the roots of the plant, In the artificial reefs, hollow hollow cubes are formed inside, and cross-shaped reinforcement pillars are formed on each side, and easy spore implantation of marine plants at the upper and lower ends of the reef spheres, of plants Providing a smooth space to achieve stable root immobilization to facilitate the habitat and growth of marine plants, the plant chain effect according to the activation of marine plants in the downward direction of the top and bottom of the reef spherical spheres, providing a place to avoid the fish and Alternative to artificial fish reef consisting of semi-circular fish spawning part with a smooth spawning place; The bottom side of the block, the left and right sides of the block, and the central bottom surface are provided with erosion preventive rests in the form of protrusions for preventing the erosion of the reef erosion and improving the resistance to current flow in the seabed bottom composed of sandy ground and clay ground. And a protector protruding upward in order to prevent breakage due to collision with a ground formed by the rock when the reef is released in the sea, and the marine benthic organism living part is provided with a hollow space capable of avoiding over- The laminated cylindrical bodies are wrapped with a binding band to be fixed. The uneven portion is made of a porous porous concrete material. Accordingly, the multifunctional artificial artificial reef for the restoration of marine ecosystem of the present invention can provide an optimal habitat by providing a habitat and a growing space for various fish and shellfish and marine plants for early restoration of the damaged coastal ecosystem, And to provide a multifunctional composite artificial reef for marine ecosystem restoration that can realize excellent marine ecosystem restoration performance at the same time.
