主要成就

科研成就

吳朝陽主持自然基金委青年基金、面上基金、優秀青年基金、傑出青年基金、重點研發課題等項目。第一或通訊發表SCI論文60餘篇，主要包括 Nature Climate Change，Nature Communications，PNAS，Global Change Biology，Global Ecology and Biogeography，Remote Sensing of EnVIronment， Agricultural and Forest Meteorology等期刊

構建了植被物候精細刻畫模型——構建了考慮溫度、降水、積雪等氣候變化因子的物候變化精細刻畫模型，提出了物候模型引入氣候變化因子的方法；建立了基于溫度時間變化的常綠林物候模拟算法，解決了現有方法在常綠林物候變化模拟中無法應用的問題；構建了不同分辨率數據物候精細刻畫的轉化模型，揭示了地表異質性對降低物候數據不确定性的決定作用

揭示了氣候變化與植被物候作用機制——揭示了冬季低溫冷激對植被春季物候提前的制約作用，對春季物候提前的趨勢提出了新的認識；發現了晝夜增溫對植被秋季物候變化的反向驅動作用，從機制上解釋了晝夜升溫不對稱性對秋季物候的影響；提出了風速減弱對高緯度植被秋季落葉期的推遲作用，揭示了風速變化對秋季物候的影響

提出了物候對生态系統碳循環影響觀點——建立了植被冠層光合作用組分的物候變化信息分解模型，提出了物候研究中應該關注有效光合作用組分信息的觀點；研發了基于降水累積效應的物候改進算法，支撐定量分解氣候變化因子對碳循環的貢獻；闡述了落葉林、常綠林對氣候變化響應敏感性差異的機制，揭示了植被秋季物候對生态系統碳循環年際變化的決定作用
