On October 29, the reporter learned from the Institute of Atmospheric Physics of the Chinese Academy of Sciences (Institute of Atmospheric Physics, Chinese Academy of Sciences) that the latest research by Liu Yi’s research team and colleagues in the United Kingdom and the United States found that China’s terrestrial ecosystem has a huge carbon sequestration capacity, but it has been seriously underestimated in previous studies , Which actually absorbs about 45% of anthropogenic carbon emissions.
This important research paper in the ecological field was published online by the internationally renowned academic journal Nature in the early morning of the 29th Beijing time.
The research team believes that the latest research adopts a method system based on atmospheric greenhouse gas concentration to calculate emission fluxes, which will provide a strong scientific basis for China's "carbon neutral" accounting and international negotiations.
The results of the study found that from 2010 to 2016, China’s terrestrial ecosystems absorbed approximately 1.11 billion tons of carbon per year, absorbing 45% of human carbon emissions during the same period.
The huge carbon sink of China's terrestrial ecosystem is mainly due to the contribution of carbon sequestration in China's important forest areas, especially the southwest forest area. At the same time, it was found that the northeast forest area also has a very strong carbon sink capacity in summer.
This is also the result of China's huge investment in restoring natural forest vegetation and strengthening plantation cultivation in the past 40 years.
Liu Yi’s research team stated that the results of the study relied to a certain extent on the new ground observation data, but due to anthropogenic emissions and large temporal and spatial changes in terrestrial ecosystems, existing observations are still insufficient.
In the future, satellites will further enhance their observation capabilities to make up for the lack of current observations, thereby establishing a more comprehensive observation system, providing more accurate carbon budget data, and providing scientific and technological support for China's "carbon neutral" goal.
