| 英文摘要 | Drought significantly constrains vegetation growth and reduces terrestrial carbon sinks. Currently, the spatiotemporal patterns and mechanisms of the differential impacts of soil and meteorological droughts on vegetation productivity remain inadequately understood. In this study, we analyzed soil moisture (SM), vapor pressure deficit (VPD), and gross primary productivity (GPP) to investigate their spatiotemporal patterns and the combined effects on GPP over China. The results revealed that: (1) Soil drought and meteorological drought generally exhibited temporally synchronous trends across China. (2) GPP was predominantly affected by the combined and synchronous effects of both SM and VPD, although their effects displayed directional variability differences in certain regions. (3) SM demonstrated a greater relative importance on GPP than VPD across more than half of the regions in China, whereas deciduous broadleaf forests were the only vegetation type primarily affected by VPD. (4) Under the lag effects, both SM and VPD exhibited bidirectional Granger causality with GPP, with the interaction between VPD and GPP proving more pronounced than that of SM. Our research provides valuable insights into the mechanisms through which SM and VPD influence GPP, contributing to improved predictions vegetation productivity and implementing ecological restoration. |
