摘　　要：2016年4月签署的"巴黎协定"的目标是到21世纪下半叶全球人为碳排放与生态系统碳汇持平,为了实现这一目标需要精确计量全球不同地区的碳通量,而全球碳同化系统是有效的技术手段。为此,国家科学技术部在"十三五"期间部署的国家重点研发计划"全球变化及应对"专项资助了"基于多源卫星遥感的高分辨率全球碳同化系统研究"项目。将发展生物圈和大气圈关键参数多源遥感协同反演技术体系、多源卫星与地面观测数据联合碳同化算法,进而建立耦合生态系统模型的高分辨率全球碳同化系统,联合同化多源观测数据,优化生态系统模型关键参数、光合和呼吸碳通量、重点区域人为源碳通量,定量揭示全球陆地生态系统和重点区域人为源碳通量时空格局、生态系统碳源汇驱动机制,为全球变化与应对专项目标的实现和国家决策提供技术与数据支持。The Paris agreement signed in April, 2016 aims to balance global anthropogenic carbon emissions and terrestrial carbon sinks by the middle of the 21st century. To fulfill this goal, it is necessary to calculate carbon fluxes of different regions reliably. The global carbon assimilation system is an effective technique for achieving this goal. The Ministry of Science and Technology of China supports the project entitled as study on the global carbon assimilation system based on multisource remote sensing data through the national key research and development programs for global change and adaptation during the thirteen-five period. This project will develop synergic inver- sion techniques for retrieving key parameters of biological and atmospheric cycles and for assimilating multisource remote sensing and ground based data. Then, the high resolution global carbon assimilation system coupled with an ecological model will be constructed. This system is able to assimilate jointly multisource observation data and to optimize key model parameters, photosynthesis and respiration carbon fluxes of global terrestrial ecosystems, and anthropogenic carbon emission fluxes of key regions. This system will be used to study quantitatively the spatial and temporal patterns of carbon fluxes of global terrestrial ecosystems and anthropogenic carbon emission fluxes of key regions and to identify the mechanisms driving the global terrestrial carbon sinks and sources. The outputs of this study wilI be helpful for the fulfillment of the key research and development programs for global change and adapta- tion and provide valuable data and technical support for the decision-making in China.
