简介刘济，副研究员，欧盟玛丽居里学者，德国洪堡学者，中国科学院高层次人才计划。2021年毕业于中国科学院大学（亚热带农业生态研究所）获博士学位，致力于生源要素的耦合循环与平衡研究，以第一/通讯作者身份在Nature Geoscience、Nature Communications、Global Change Biology等期刊发表论文18篇，并参与撰写英文专著Soil Constraints and Productivity。现任 Global Change Biology（编委） 、Journal of Ecology（副主编）、Functional Ecology（副主编）、ENGINEERING Agriculture（学科编辑）等期刊编委。主持过欧盟地平线框架计划、德国洪堡基金、中国科学院高层次人才计划、国家自然科学基金（面上项目与青年项目）等科研项目。
研究方向生态化学计量及碳氮磷耦合循环，旨在阐明维持化学计量平衡的动态内稳态调控机制，并揭示全球变化下化学计量偏移对生态系统韧性、养分利用效率及可持续性的级联反馈效应。1）系统证实海洋C:N:P计量比在过去半个世纪呈现显著的时空漂移，该发现为重新审视经典的Redfield比恒定假设提供了关键实证依据；2）基于长期野外观测建立土壤-水体计量定量传递关系，识别出触发水质响应的关键计量阈值（C:P>97.8）与景观阈值（2000 ha），推动流域治理从“负荷管控”转向“源头诊断-阈值识别”的精细化范式；3）揭示农业普遍计量失衡及养分利用效率低于50%的格局，并识别中美玉米带为全球最大氮磷盈余区，提出基于计量平衡的“增产-固碳-减排”协同调控框架，形成“诊断-溯源-预测-优化”技术体系。
