中国科学院新疆生地所在《Nature Ecology & Evolution》发表近40年全球极端高温事件对陆地生态系统碳汇能力影响原创性研究成果（图）
高温 生态系统 吸收
font style='font-size:12px;'>
2024/11/14
全球陆地生态系统通过光合作用每年吸收近1/4人类活动排放的CO2，在减缓全球变暖中发挥了关键作用。然而，随着全球范围内极端高温事件频率和强度的持续增加，陆地生态系统的CO2吸收能力受到了极大挑战。目前研究大多集中在持续时间较长的单一极端事件或单一地区的定量评估工作，缺乏对全球范围内极端高温事件的长期趋势对陆地生态系统吸碳与排碳等环节，以及高温极端条件下水热条件转变对陆地生态系统碳汇能力影响的全面揭...
