Carbon sequestration process and carbon storage mechanism of reef ecosystem in South China Sea
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 3.5×106～4.5×106 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.
