研究方向

高寒生態系統碳循環與全球變化

主要研究成果

圍繞全球變化背景下陸地生態系統碳匯變化機制，聚焦大氣CO2濃度升高和植物可利用氮變化對陸地生態系統碳匯功能的影響，開展了如下研究：（1）構建植被-土壤碳庫周轉理論模型，以此為紐帶，結合控制實驗觀測和過程模型模擬，定量揭示了1960年代以來大氣CO2濃度升高，通過光合作用底物增加效應，對北溫帶和全球陸地碳匯增加的貢獻，指出考慮了氮過程的模型平均高估了氮對植物生長的限制作用（發表於Nature Geoscience）。（2）大氣CO2濃度升高不僅增加植物光合作用底物，還與其他溫室氣體共同導致氣候變暖，繼而影響植物生長。基於遙感觀測、大氣反演、模型模擬數據解析了陸地植被固碳對氣候變暖回響的季節分異及其空間格局。觀測和模型結果均表明，在熱帶地區，氣候變暖降低各季節植被固碳速率；然而，在高緯度生態系統，升溫促進春季植被固碳，卻降低夏季植被固碳速率，存在季節補償效應。（發表於Journal of Climate、Journal of Geophysical Research-Biogeosciences等）。（3）針對模型模擬不確定性較大的高寒地區，基於觀測揭示青藏高原無機氮濕沉降量、空間格局和傳輸路徑，並發現氮沉降增加非線性地促進高寒植物群落水平碳吸收，但植物生長氮限制特徵存在種間差異，且高寒植物生長氮限制還受水分條件和草原管理共同調節（發表於Atmospheric Chemistry and Physics、Plant and Soil、Science of the Total Environment、Catena等）。
