abstract = "{This study investigated the attribution of terrestrial water storage
(TWS) variations across China to changes in groundwater and
human water use. As one vital storage component, the groundwater
storage (GWS) derived from the Jet Propulsion Laboratory's GRACE
(Gravity Recovery and Climate Experiment) mass concentration
solution compared reasonably well with the in situ groundwater
table depth, with the correlation coefficients ranging from
-0.83 to -0.18, all of which were statistically significant at
the 95\% confidence level. About 71\% of the trends in derived
GWS had the same sign as those of observations, without
systematic deviation, across China. The GWS variation
contributed a large portion of the TWS trend in most regions of
China, and the majority of contribution values reached
50\%-150\% in the Hai River basin, the Loess Plateau, and the
middle portion of the Yangtze River basin. The dominant role of
GWS is closely related to the detected long-term ``memories'' in
both TWS and GWS. The increase of irrigation consumption
accelerated the TWS depletion trend by 13.4\% in the Huai River
basin, while the decrease of consumptive agricultural water use
alleviated the TWS decline rate by 4.1\% in the Hai River basin.
Importantly, the correlation coefficients reached 0.74-0.95
between the TWS change and the residual of precipitation,
evapotranspiration, flow into the sea, and irrigation
consumption in the four river basins of particular interest. The
findings of this study are helpful for understanding regional
water cycles in China.}",
