全球/区域生态系统碳循环研究具有多台站联网观测、多源异构数据、多模型综合分析、跨领域科学家协同工作等特点。以中国陆地生态系统通量观测研究网络（ChinaFLUX）为基础平台,论述建立碳循环科研信息化环境（e-Carbon Science）的迫切性,系统阐述e-Carbon Science的目标、组成、关键技术及研究进展,构建了由＂四环境（碳循环数据集成与服务环境、模型模拟环境、可视化分析环境、科研协同工作环境）、三系统（站点、区域、全国尺度陆地生态系统碳收支评估应用系统）＂组成的ChinaFLUX e-Carbon Science,形成ChinaFLUX通量数据采集—传输—存储—管理—处理—可视化—共享服务的一体化系统,实现不同尺度的碳收支快速评估与模拟,支撑并促进我国陆地生态系统碳循环研究和生态信息学发展,对我国野外台站网络信息化起到引领和示范作用。“,”Global and regional ecosystem carbon cycle research is characterized by multi-stations observation networks,multi-sources data with heterogeneous structure,multi-models meta-analysis,and collaboration of scientists across different disciplines.Based on the Chinese Terrestrial Ecosystem Flux Research Network（ChinaFLUX）,we proposed an e-Carbon Science with its goals,components,and key techniques and reported current progress.ChinaFLUX e-carbon science consists of four environments（the carbon cycle data integration and service environment,the model simulating environment,the visual analysis environment,and the collaborative scientific research environment） and three application systems（terrestrial carbon budget assessment system at local,regional,and national scales）.We developed an integration system of flux data acquisition-transportation-storage-management-processing-visualization-service sharing.ChinaFLUX e-carbon science made rapid carbon budget assessment and simulation possible,promoted the development of terrestrial ecosystem carbon cycle research and eco-informatics in China,and played an exemplary role in constructing the informatization of field station networks.
