[Abstract]:In order to achieve the Paris Agreement of April 2016, which aims to achieve global anthropogenic carbon emissions equal to ecosystem carbon sinks by the second half of 21th century, the precise measurement of carbon fluxes in different parts of the globe is required, And the global carbon assimilation system is an effective technology. The National key R & D Plan "Global change and response", deployed by the State Ministry of Science and Technology during the 13th Five-Year Plan, has funded the project "High Resolution Global carbon assimilation system Research based on Multi-source Satellite remote Sensing". Multi-source remote sensing cooperative inversion system for key parameters of biosphere and atmosphere, Multi-source satellite and ground observation data are combined with carbon assimilation algorithm, and then a high-resolution global carbon assimilation system coupled with ecosystem model is established. The key parameters of ecosystem model, photosynthesis and respiration carbon flux, are optimized by combining assimilation of multi-source observation data. The carbon fluxes from anthropogenic sources in key regions reveal quantitatively the temporal and spatial patterns of anthropogenic carbon fluxes in global terrestrial ecosystems and key regions, and the driving mechanism of carbon sources and sinks in ecosystems. Provide technical and data support for the achievement of global change and response goals and national decision-making.
