Rocky reef habitat is an essential part of marine ecosystems because it boasts complex plant and animal communities,high biomass,stable material cycles and energy flows.However,human ac-tivities and frequent weather disasters have caused rocky reef habitat loss and biodiversity loss.There-fore,restoring degraded rocky reef habitats is considered a top-priority action.In this paper,we applies ecological theories such as ecological niche theory,succession theory,edge effect theory and disturb-ance-stability theory to restore the concrete rock reef ecosystem.As eco-concrete has a complex pore structure,rough surface and high strength,its application can offer an attachment base and habitat for marine organisms.Therefore,eco-concrete can be used to restore oyster reefs,algal reefs,coral reefs and ecological seawalls,to build an ecosystem with engineering values,to purify water,to provide bio-logical habitat,to maintain biodiversity and to resist wave erosion and to achieve sustainable develop-ment.We aimed to protect and restore ecology by conducting research on eco-concrete in terms of its design,production,and construction technology.By doing so,the reef ecosystem survey technology,and an eco-concrete reef ecosystem modular restoration technology system were established,which should improve the management of the eco-concrete reef ecosystem.
