(1) 解析了全球变化背景下土壤碳库的变化特征：发现尽管冻土融化会造成青藏高原气候敏感区土壤碳库减少(Environmental Research Letters, 2018, 共同一作)，但至今尚未造成全球尺度土壤碳损失(Global Change Biology, 2015, 第一作者)，未形成对气候变暖的正反馈。该发现并不支持经典正反馈假说中“气候变暖会导致土壤有机碳丢失”的传统观点，丰富了学术界对碳循环与气候变化之间反馈关系的认识。

(2) 阐明了土壤碳分解及其激发效应的调控因素：发现表层土壤碳分解释放的空间变异主要受底物可分解性控制，而深层土壤则主要取决于微生物的相对丰度(Nature Communications, 2016, 第一作者)。进一步研究发现，底物可分解性和土壤物理化学保护是导致高寒草地表层土壤碳激发效应空间变异的关键因素，其作用超过了传统的植被、土壤和微生物属性(Nature Communications, 2019, 共同一作)。这些结果明确了土壤碳稳定性机制和土壤微生物在有机质分解中的重要作用，为发展地球系统模型提供了重要启示。

(3) 揭示了氮素调控土壤碳动态的微生物机制：发现土壤碳激发效应的强度沿冻土融化形成的自然氮梯度呈现下降趋势，且该梯度的变异主要取决于微生物代谢效率，但不受微生物胞外酶活性调控 (Nature Communications, 2018, 第一作者)。该发现突破了学术界以往关于“激发效应强度主要受微生物酶活影响”的传统认识，为准确理解全球变化背景下碳-氮交互作用提供了新视角。
