摘　　要：大气中CO2浓度上升是全球气候变暖的重要原因,陆地生态系统碳汇显著减缓了大气中CO2浓度上升和全球变暖的速度,但具有明显的时空变异性。全球碳同化系统是精确监测全球不同地区陆地生态系统碳汇的有效技术手段。本文将介绍全球碳同化系统的发展动态,国家重点研发计划项目“基于多源卫星遥感的高分辨率全球碳同化系统研究”的目标和主要研究内容,以及已经取得的主要进展,并展望了未来应用前景。Increase of atmospheric C02 concentration is the main driver for global warming.Terrestrial carbon sink plays an important role in retarding increase of atmospheric C02 concentration and global warming.However,this sink has large spatial and temporal variations.The global carbon assimilation system is an effective technique for reliably monitoring terrestrial carbon sink in different regions of the globe.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.This paper will introduce the main objectives,research focuses and main achievements of this project.The prospect of this system will also be highlighted.
