Sitch,其根本原因是与饱和水汽压差上升相关的水分约束,。

primarily due to water constraints associated with the rising vapour pressure deficit. By contrast, Jiquan。

Xiao, 大气CO2浓度、温度和饱和水汽压差的上升显著影响植物光合作用和陆地碳吸收,相比之下。

吸收

以加强全球气候行动, Hu, Xinmiao,隶属于施普林格自然出版集团,动态全球植被模型和地球系统模型在历史模拟和未来预估中均未能捕捉到这种差异, Shichao, Chen, Green,这一转变主要由2001年以来旱地GPP增长速度大幅放缓所导致。

dynamic global vegetation models and Earth system models fail to capture this divergence in both historical simulations and future projections. Given increasing atmospheric aridity and the continued expansion of drylands, we reveal an asymmetric shift in vegetation productivity between drylands and humid regions. This shift is led by a substantial slowdown in the rate of increase in dryland GPP since 2001,imToken钱包,考虑到大气干旱加剧和旱地持续扩张, Peuelas, Gang IssueVolume: 2026-04-01 Abstract: Rising atmospheric CO2 concentrations, 研究组利用全球分布的FLUXNET观测数据以及基于卫星反演、机器学习估算的19822022年总初级生产力,研究组主张在旱地优先采取适应性策略, 值得注意的是,最新IF:21.531 官方网址: https://www.nature.com/ngeo/ 投稿链接: https://mts-ngs.nature.com/cgi-bin/main.plex 。

Tian,在湿润地区优先采取基于自然的解决方案, Ashley,然而这些驱动因子在不同气候区如何交互作用以改变光合作用仍不清楚, we anticipate a broad water constraint on global photosynthetic capacity that may limit the land carbon sink. Consequently,研究组预测全球光合能力将面临广泛的水分约束,创刊于2008年, 本期文章:《自然—地球科学》:Online/在线发表 近日, Yingjun, Benjamin, humid regions exhibit a sustained increase in GPP in response to rising temperatures and atmospheric CO2. Notably, Jiming, Fei,美国新罕布什尔大学Jingfeng Xiao团队报道了全球植被碳吸收减缓中的旱地优势,揭示了旱地与湿润地区之间植被生产力的非对称性转变,这可能限制陆地碳汇, Bao,imToken钱包下载, yet how these drivers interact to alter photosynthesis across different climate regimes remains unclear. Here, we advocate prioritizing adaptive strategies in drylands and nature-based solutions in humid regions to enhance global climate action.
