Abstract：The seagrass bed ecosystems of coastal wetlands have important ecological functions in slo-wing down water flow,purifying water and fixing carbon.In this paper,the carbon sink effect,heavy metal absorption and enrichment effect of seagrass beds are reviewed,the sources of organic carbon in seagrass beds,the absorption,transferring and tolerance mechanisms of seagrass heavy metals are ex-plored,the impact of seagrass on the distribution of heavy metals in sediments,and the potential appli-cation of seagrass as indicator species of heavy metals in the environment are analyzed,and the environ-mental factors affecting the accumulation of organic carbon are explained.The research prospects on the carbon sink estimation of seagrass bed,seagrass monitoring and management,heavy metal form,source and ecological risk analyses,interaction studies between sediment organic carbon and heavy met-als,and application potential of seagrass as the pioneer species of ecological restoration are put for-ward.
