摘　　要：Seagrass is not only known for its ecological role,but also for its high capacity on the carbon sequestration.Although the area of seagrass meadows was less than 0.2% of the world’s oceans,the yearly organic carbon burial of seagrass reached 10% of that in the ocean.Anthropogenic activities in the past two decades and the climate change have led to a significant decrease of seagrass meadow.Since seagrass is widely distributed along the coastline of China,it is necessary to put more efforts on the seagrass conservation and restoration,which will consequently be a suitable nature based solution for mitigating the climate change.This paper provides a comprehensive review on the following five aspects:1)the seagrass distribution in China;2)the role that seagrass plays in the climate mitigation;3)carbon sequestration of seagrass in China;4)loss of seagrass habitats and 5)the restoration of seagrass habitat in China since 2013.Current research gap and prospective research direction were also pointed out in this study.海草床作为近岸海域重要的生态系统,不但具有生态功效,而且具有较高的固碳能力。海草床虽只占不到0.2%世界海洋面积,但海草床每年有机碳埋藏量占海洋每年有机碳埋藏量的10%。近二十年来,人类活动的加剧和气候变化导致海草床面积显著减少。由于海草广泛分布于中国海岸带,因此进行海草床的修复和保护有助于减缓全球气候变化。本文从以下五个方面进行了综述:(1)中国海草床的分布;(2)海草床在应对气候变化中的作用;(3)中国海草床的固碳作用;(4)海草生境的丧失;(5)2013年以来中国海草床的生态修复工作。文章的最后指出了目前研究的空白和未来的研究方向。
