摘要:

红树林、滨海盐沼和海草床是典型的滨海蓝碳生态系统,具有相当可观的固碳能力。植被碳库和沉积物碳库是蓝碳生态系统有机碳的主要载体,其变化过程决定了生态系统的整体固碳能力。本文尝试从碳库相互作用的角度出发,通过文献梳理,总结不同植被碳库之间、不同沉积物碳库之间以及植被碳库和沉积物碳库之间相互作用的研究进展,指出物种竞争、外源碳输入以及生物地貌学过程在碳库相互作用中所起到的重要作用,并提出滨海蓝碳生态系统碳库研究中存在的问题和未来研究的方向。

Abstract:

Mangroves, coastal salt marshes and seagrass beds, as the typical coastal blue carbon ecosystems, have been widely recognized for their remarkable capacity in carbon storage. Vegetation carbon pool and sediment (or soil) carbon pool were considered to be the major carbon pools within the coastal blue ecosystems and their variations determined the overall carbon sequestration of the ecosystems. From a perspective of carbon pool interactions, this study summarized the previous research work based on literature review, including the interactions within various vegetation carbon pools and within various sediment carbon pools, as well as the interactions between vegetation and sediment carbon pools. Interspecific competition, allochthonous carbon input and biogeomorphology were found to be the key to understand the carbon pool interactions. Finally, a perspective on the current state-of-the-art of blue carbon pool study is offered, with challenges and suggestions for future directions.
