The invention discloses a star-like radial allocation method for artificial reefs, which is characterized in that a cubic reef form with the side length of 1 to 2 meters is used as a main reef, 3 to 8 auxiliary reefs with the height of 80 to 120 centimeters are uniformly distributed on the circumference which uses the main reef as the central point, the main reef and each auxiliary reef are connected through a stone connection bridge with the length of 3 to 6 meters, and the categories of the adjacent auxiliary reefs are diverse. The artificial reefs are closer to the reality and are favorable for the balance of the ecological system, and the stone connection bridge serving as a radiation belt provides a bridge for the movement of rare seafood among the reefs and plays a role in sheltering. Through on-site sea area tests, the rare seafood such as sea cucumber, sea hedgehog, abalone and the like can rest in gaps among the main reef, the auxiliary reefs and the stone connection bridges or on the surfaces; the good growth condition of algae on the reefs provides baits for the rare seafood, so the proliferation effect of the rare seafood is obvious; and reef-associated fishes such as hexagrammos otakii, sebastes schlegeli and the like rest in the main reef and the auxiliary reefs, so the whole reef group structure is stable and forms a good small ecosystem.
