摘要
岩礁生境具有复杂的动植物群落、较高的生物量、稳定的物质循环和能量流动,是组成海洋生态系统的重要生境.高强度的人类活动和频繁的气候灾害,造成岩礁生态系统退化或丧失,生物多样性降低.生态位理论、演替理论、边缘效应理论、干扰-稳定性理论等生态学理论为生态混凝土岩礁生态系统修复提供了理论依据.生态混凝土具有复杂的孔隙结构、粗糙的表面和较高的强度,为海洋生物提供了附着基和栖息地.利用生态混凝土修复藻礁、牡蛎礁、珊瑚礁和生态海堤,建设具有净化水质、提供生物栖息地、维护生物多样性和抵御海浪侵蚀等生态功能和工程价值复合的生态系统,满足了人与 自然可持续发展的要求.生态混凝土修复岩礁生态系统要以生态保护修复为核心,加强生态混凝土设计、制作和建设技术研究,构建岩礁生态系统调查技术,建立生态混凝土-岩礁生态系统模块化修复技术体系,完善生态混凝土-岩礁生态系统的管理.
Abstract
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.
