主要研究兴趣
1. 区域与全球生态学:整合多尺度生态系统联网观测、遥感监测和全球数据库,揭示陆地生态系统结构、功能及关键生物地球化学过程的时空演变规律,阐明生物多样性、气候与土壤环境对生态系统碳、氮、水循环及其耦合关系的协同调控机制,探索生态系统功能对全球变化的非线性响应与临界转变,为理解和预测全球陆地生态系统的演变提供科学依据。
2. 全球变化生态学:依托全球变化野外控制实验和长期定位观测,研究气候变化与人类活动对陆地生态系统结构、功能及稳定性的影响,揭示植物–土壤–微生物相互作用对生态系统碳、氮、水循环及其耦合过程的调控机制,阐明生态系统对全球变化的响应路径、适应机制及其环境依赖性,为理解生态系统功能维持与碳汇可持续性提供理论支撑。
