Mechanistic responses of phosphorus-limited forests to CO2 enrichment

在人类排放的推动下，二氧化碳继续在大气中积累。全球森林碳汇可显著减缓大气中二氧化碳的增加，有助于减缓气候变化，但对其未来命运的了解仍然很少，阻碍了减缓和适应规划。一个关键的差距与磷的作用有关，磷对限制澳大利亚林地和热带森林的生产力至关重要。基于桉树林中CO2 x P交叉实验（EucFACE）结果的模型-数据融合将有助于缩小这一重要的知识差距，并在用于气候和排放评估的领先全球模型中利用新的机制知识。

Carbon dioxide continues to accumulate in the atmosphere, driven by human emissions. The future fate of the global forest carbon sink, which significantly slows CO2 increase in the atmosphere, helping to dampen climate change, remains poorly constrained, hindering mitigation and adaptation planning. A key gap concerns the role of phosphorus, crucial in limiting the productivity of Australian woodlands and tropical forests. Model-data fusion based on the results of a crossed CO2 x P experiment in Eucalyptus forest - EucFACE - will help close this vital knowledge gap, and leverage new mechanistic knowledge in a leading global model used for climate and emissions assessment.
