The release of artificial reefs can rebuild the ecological community in the sea area, and play an important role in the restoration of the marine ecological environment and the conservation of fishery resources. The analysis of the construction of artificial reefs through scientific evaluation can ensure that the construction of artificial reefs is reasonable and feasible. Considering both the natural environment and the social environment, 20 evaluation factors including hydrology, water quality, sediments, marine ecology, geological landforms, and marine functional zoning are selected to establish evaluation criteria for single-factor suitability evaluation of the evaluation factors. Determine the weight of each evaluation factor, build a comprehensive evaluation model for the suitability of artificial reef construction, and analyze the suitability of artificial reef construction in the 155 km2 aquaculture sea area around Xingshutun, Dalian. The results show that there are 2 areas most suitable for artificial reef construction in this aquaculture sea area, and 1 area that is more suitable for artificial reef construction. The research shows that the comprehensive conditions in the northeast and southeast of the aquaculture sea area are good and suitable for the construction of artificial reefs.
