“…Our results demonstrate that the relationships between VPD/SWC and GPP were influenced by climatic interactions (Figures 1a, 3, and 4e; Figures S5–S8), emphasizing that GPP sensitivity to VPD and SWC may differ under different climatic conditions. For example, the relationship between GPP and VPD was negative under dry conditions, but positive under wet conditions in Chinese grassland ecosystems (Chen et al, 2021). Furthermore, the VPD–GPP relationship is strongly influenced by climatic drivers (Figures 1a and 3), which may reflect the greater variability of VPD within a few hours caused by atmospheric drivers, compared with SWC changing slowly over several days (Sulman et al, 2016).…”

“…Dryness stress on ecosystem production has often been characterized by low soil water content (SWC) and high atmospheric water demand (i.e., vapor pressure deficit, VPD; Liu et al, 2020). The impacts of VPD and SWC on plants have been studied in recent years against the background of global warming (Chen et al, 2021; Denham et al, 2021). However, the dominance of VPD versus SWC on plant water stress is still under debate (Fu et al, 2022; Liu et al, 2020; Sulman et al, 2016; Yuan et al, 2019).…”

“…Similar to the results of previous studies, the GPP we obtained varied with VPD as a unimodal curve, which was mainly manifested at all the FLUXNET forest sites. Studies have shown that when the VPD threshold is 6-8 hPa, and it determines whether the GPP response transitions from a significant increase to a decrease (Chen et al, 2021). Our results suggested that an increasing VPD under climate change could reduce forest CO 2 uptake (Sulman et al, 2016).…”

“…However, when the VPD is large, plants will close part of their stomata to reduce the loss caused by transpiration. Studies have shown that in forest ecosystems, GPP is not always restricted by the VPD, which is mainly due to forests having a stronger water holding capacity and deeper root systems (Beer et al, 2007;Chen et al, 2021;Gui et al, 2021). The GPP in these places is mainly affected by radiation or temperature.…”
