Measurement method of blue carbon sink and its potential assessment

Climate change is an important issue facing the world today, which restricts the sustainable development of human economy and society. As the richest and most active carbon source sink on the planet, the blue ocean plays a decisive role in the global ecosystem. This paper discusses the blue carbon measurement method and monitoring system for mangroves, tidal flat wetlands, fisheries, salt marshes and seagrass restoration from the perspective of methodology. It evaluates the blue carbon potential in China's oceans so as to promote the integration of blue carbon into climate change governance mechanisms in the direction of internationalization, standardization, and specialization. It provides reference for the implementation of blue carbon measurement standards and their methodological applications.
