The enhanced key-food-web offshore restoration technique by wall roughening is proposed in this approach. Three kinds of wall roughening, i.e. artificial reefs, hard slope roughing and the integration of artificial reefs and hard slope roughing are applied to enhance the original key-food-web offshore restoration technique. The effects of ecological rehabilitation of the proposed enhanced key-food-web offshore restoration technique are predicted by the models of Ecopath model and ocean health index. The results indicate that the ecological rehabilitation of the enhanced key-food-web offshore restoration technique with different wall roughening is better than that of the original one. Among them, the enhanced key-food-web offshore restoration technique with the integration of artificial reefs and hard slope roughing is the best. After using it, the restored offshore ecosystem is the most mature, and the ocean health index is increased to 87.1 or 87.3 with respect to the case of 2% or 0.57% artificial reef for the conservative or optimistic analysis.
