Research on carbon cycle and carbon balance has always been one of the hot spots of global attention, and forest ecosystems, as the largest carbon reservoir in terrestrial ecosystems, are of great importance to the global carbon cycle. As an important component of forest ecosystems, the study and analysis of carbon fluxes in coniferous forest ecosystems is key to understanding the impact of global climate change on the carbon cycle. However, traditional carbon flux data management suffers from lack of data and untimely sharing. Therefore, based on the observation of ecosystem carbon fluxes, this paper designs and studies a carbon flux data management information system to unify the data management, improve the processing and analysis of carbon fluxes, provide data support and services for the carbon cycle of coniferous forest ecosystems, and also help predict future climate change trends, which is the key to cope with global changes.
