On January 7, at the Yellow and Bohai Sea Blue Carbon Monitoring and Assessment Research Center located in the Yantai area of the Shandong Pilot Free Trade Zone, researchers are analyzing the carbon storage of wetland vegetation, interpreting satellite remote sensing and drones of salt marsh wetlands and seagrass beds Data, through professional laboratory instruments and equipment, assess the carbon storage and distribution area of different survey areas. The staff told the reporter: "Yantai is rich in blue carbon resources such as shellfish farming and seagrass beds, and has the conditions to achieve breakthroughs in developing the 'blue carbon economy' and promoting the transformation and upgrading of the marine economy."
The so-called "blue carbon" refers to the processes, activities and mechanisms that use ocean activities and marine organisms to absorb carbon dioxide in the atmosphere and fix and store it in the ocean. Its biggest premise is the rich marine resources. In recent years, the Yantai area has taken the development of the blue carbon economy as an important entry point for the transformation and upgrading of the marine economy, striving to transform the advantages of the ocean into ecological advantages and development advantages, actively serving the national strategy of "carbon peaking and carbon neutrality", and striving to create a marine economy A national model of high-quality development.
In April last year, the Marine Disaster Reduction Center of the Ministry of Natural Resources signed a cooperation agreement with the Shandong Provincial Oceanic Bureau, relying on the Shandong Provincial Institute of Marine Resources and Environment to jointly build the "Yellow Bohai Sea Blue Carbon Monitoring and evaluation Research Center" and the Marine Ecological Early Warning Field Scientific Observation and Research Station . The platform will focus on the monitoring and evaluation of various carbon sink background values in the Yellow River Delta region, expand the potential ways and means of increasing blue carbon sinks in Shandong Province, carry out pilot monitoring and evaluation of estuaries, wetlands and seagrass beds, and conduct monitoring and evaluation of marine biological carbon sequestration , marine ecological early warning new technology research and other series of work.
At present, the platform has carried out field surveys in the distribution area of Long Island islands and reefs, and the distribution area of seagrass beds in Xikou Bay, Chang Island-Miao Island, to determine the types of seagrass and reefs, and to obtain relevant data information and image materials. In the mouth of the Yellow River, the carbon storage survey of the salt marsh ecosystem and the monitoring of the distribution of seagrass beds in Shandong Province were carried out, and the "Research Report on the Investigation and evaluation of Carbon Storage of Salt Marsh Ecosystems and Seagrass Beds in Shandong Province" was compiled, which was the first to achieve "carbon peaking" for Shandong , carbon neutrality” provides strong support.
At the same time, relying on the Provincial Key Laboratory of Marine Ecological Restoration, the platform carried out technical surveys and blue carbon assessments. With the goal of "verifiable, reportable, and measurable", the platform evaluated the total carbon storage and annual carbon in the Yantai area of the free trade zone. Sinks, an overall grasp of the blue carbon ecosystem distribution, current status and changing trends, find out the background of blue carbon resources, and provide data support for effectively exerting the role of coastal wetlands and oceans in sequestering carbon, and improving the capacity of marine ecological carbon sinks.
"The construction of this platform is of great significance for the Yantai Free Trade Zone to explore the use of marine organisms for carbon sequestration, establish and improve the ecological compensation mechanism, and promote energy conservation, emission reduction and ecological environment protection. important basic data.” said Xu Xishui, member of the Party Committee of Yantai Development Zone Marine Economic Development Bureau and director of the Marine Economic Division.
