Under the conditions of better growth vigor and proper distribution, the coral reef can provide better disaster prevention and reduction functions for extreme disasters such as storm surge and the like. However, coral reefs are subject to threats including global climate change, human activity, pollution, excessive fishery, etc., nearly half of the coral reefs have been severely degraded, and two-thirds of the coral reefs are severely threatened. However, restoration of the coral reef ecosystem is an extremely complex and lengthy process. At present, in the aspect of repairing the coral reef ecosystem, the manual intervention is the most direct and quick-acting means, and in the manual intervention means, more artificial reefs are put in. The artificial reef part put in at present is broken when encountering extreme weather due to the reasons of structure or materials, and the artificial reef part is washed away by ocean currents. The ocean currents may wash away the reef body and may also wash away the coral reef on the reef body. In addition, the external surface of the artificial reef body has few designs for promoting the attachment of coral worms or transplanting coral seedlings, so that the repair effect is poor. As disclosed in patent CN103960179a, the body is a concrete block with vertical perforations, and no steel bar or other metal reinforcing ribs are contained in the body but micro silicon powder is doped in the body; the body is a table-shaped object with a small upper part and a big lower part; the side of the body is provided with a plurality of holes penetrating through the vertical perforation and a plurality of pits.
