abstract = "{Groundwater is a crucial water resource of the Qinghai-Tibet Plateau
(QTP), accounting for about 85\% of the total water resources.
However, the scarcity of data on groundwater storage (GWS)
changes limits our understanding of its response to climate
warming and cryosphere degradation. In this study, we combined
GRACE/GRACE-FO satellite gravimetry, ICESat-2 altimetry, GLDAS
land-surface model outputs, and in situ groundwater observations
to quantify spatiotemporal GWS changes across the QTP from 2004
to 2020 and analyse the controlling factors of GWS changes.
Results indicate that internal and external factors jointly
control GWS on the QTP. With the Pamir{\textendash}Karakoram{\te
xtendash}Gangdise{\textendash}Tanglha{\textendash}Hengduan
Mountains as the boundary, GWS exhibits an increasing trend in
northern QTP and a decreasing trend in southern QTP. Accelerated
permafrost degradation both increases soil permeability and
enhances its water-holding capacity. In the gently sloping
central{\textendash}northern region, abundant glacier-snow
meltwater combined with favourable topography creates conditions
for GWS to rise. Conversely, the pronounced relief of the
southern, western, and eastern sectors restricts effective
meltwater recharge to aquifers. At the same time, higher
evapotranspiration and reduced precipitation in the south and
west may also lead to declines in groundwater storage. These
findings highlight the heterogeneous impacts of climate change
on groundwater resources across different hydrogeological zones
of the QTP. The results provide important scientific support for
regional water resource management and adaptation planning in
the face of ongoing environmental change.}",
