| 摘要: |
| 海南岛拥有我国最典型的热带海草床资源，凭借独特的热带气候与近岸海洋环境，其碳汇功能在我国热带沿海生态保护、区域蓝碳布局及全球气候变化应对中具有不可替代的战略价值。本文系统梳理了海南岛海草床碳汇功能的研究进展，构建了“机理—现状—影响因素—增汇路径”的综合分析框架。首先，阐述了海草床碳汇功能的形成机理；其次，评估了海南岛海草床碳汇的现状特征，分析了其分布格局、碳储量空间异质性及评估方法中的不确定性；再次，剖析了影响碳汇功能的关键因素，区分了自然背景条件(水文动力、沉积环境)、人为干扰(富营养化、海岸开发)及气候变化等多重胁迫；最后，从生态修复、适应性管理、政策与市场机制等方面提出了提升海南岛海草床碳汇功能的路径与策略。本文旨在为海南岛海草床碳汇资源的科学保护、系统修复与可持续管理提供理论依据，助力区域蓝碳发展与“双碳”目标的实现，并指出未来应重点在长期生态过程观测、精准监测技术、适应性管理框架、生态产品价值实现及区域协同创新5个方面深化研究。 |

| Abstract: |
| Hainan Island boasts China's most typical tropical seagrass bed resources.Because of the unique tropical climate and coastal environment,its carbon sink function plays an irreplaceable strategic role in China's tropical coastal ecological protection,regional blue carbon planning,and response to global climate change.This paper systematically reviews the research progress regarding the carbon sink function of seagrass beds in Hainan Island and constructs a comprehensive analytical framework covering the mechanisms,current status,influencing factors,and enhancement pathways.Firstly,it elaborates on the formation mechanisms of seagrass bed carbon sinks.Subsequently,it evaluates the current characteristics of carbon sinks in Hainan Island's seagrass beds,analyzing their distribution patterns,spatial heterogeneity of carbon stocks,and uncertainties in existing assessment methods.This paper then explores the key factors influencing the carbon sink function,differentiating between natural background conditions (hydrodynamics and sedimentary environment) and anthropogenic disturbances (eutrophication and coastal development),as well as climate change.Finally,it puts forward pathways and strategies to enhance the carbon sink function of Hainan Island's seagrass beds,focusing on ecological restoration,adaptive management,policy tools,and market mechanisms.This review aims to provide a theoretical basis for the scientific conservation,systematic restoration,and sustainable management of seagrass bed carbon sink resources in Hainan Island,thereby supporting the development of regional blue carbon and facilitating the achievement of the “dual carbon” goals.Future research should focus on five key areas:long-term ecological process observation,precise monitoring technologies,adaptive management frameworks,realization of ecosystem product value,and regional collaborative innovation. |
