摘　　要：珊瑚礁生态系统在全球碳循环和气候变化中发挥着重要作用。珊瑚礁生态系统是潜在的蓝色碳汇,我国珊瑚礁总面积约占全球的11%,每年的固碳量大约在3.5×10^(6)~4.5×10^(6)t之间。珊瑚礁生态系统的总储碳量非常巨大,同时珊瑚礁生态系统作为碳库在碳交易中具有非常大的潜在应用价值。文章综述了珊瑚礁生态系统中的固碳过程及储碳机制,包括碳酸盐泵、生物泵和微型生物碳泵,阐述了三种碳泵的研究进展。同时,针对目前研究存在的不足和问题,提出未来研究方向,以期为南海岛礁珊瑚礁生态系统的保护和管理提供科学依据。Coral reef ecosystems play a crucial role in global carbon cycling and climate change.They serve as potential blue carbon sinks,with coral reefs in China covering approximately 11%of the global area.The annual carbon sequestration of these reefs is estimated to be 3.5×10^(6)~4.5×10^(6) t.The total carbon storage capacity of coral reef ecosystems is immense,and they have significant potential value as carbon reservoirs in carbon trading.This article provides a review of carbon sequestration processes and storage mechanisms in coral reef ecosystems,including carbonate pumping,biological pumping,and microbially-mediated carbon pumping.The research progress on these three carbon pumps is discussed.Additionally,the article highlights the limitations and challenges in current research and proposes future research directions,aiming to provide scientific basis for the conservation and management of coral reef ecosystems in the South China Sea.
