Abstract

The blue carbon function and carbon sequestration potential of coastal ecosystems, such as salt marshes, mangroves and seagrass beds, have emerged as one of the long-term solutions to mitigate global climate change. However, the blue carbon sequestration technology has been neglected in most ecological protection and restoration projects of coastal ecosystems. Besides, in the process of project implementation and management, the dynamic monitoring and systematic evaluation of carbon sink are imperfect. This study proposes the concept of enhancement of coastal blue carbon, focusing on four key technologies of soil carbon emission reduction technology, plant carbon sequestration technology, soil microbial carbon sequestration technology, and carbon deposition and burial technology, to explore the technology system and approach to enhance coastal blue carbon. This study suggests accelerating forward-looking layout and system research, mainly by developing technologies of coastal blue carbon sequestration, achieving synergies between ecological conservation and restoration and carbon sequestration, strengthening the monitoring and evaluation of carbon sequestration and sink enhancement, and establishing a longterm management mechanism for the development of coastal blue carbon sink, which would provide theoretical and technical support for the formulation of coastal blue carbon and the enhancement of carbon sink function, and play an active role in enhancing ecological carbon sink capacity and achieving the goal of carbon peak and carbon neutrality in the future.
