Application of eco-concrete in rocky reef ecosystem restoration and associating prospects
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.
