     abstract = "{Groundwater is the world's largest freshwater resource after ice caps
        and glaciers, and its over-exploitation can disrupt regional
        hydrological cycles, leading to issues such as land subsidence
        and salinization. Identifying hotspots and drivers of
        groundwater storage changes is essential for sustainable water
        management and climate change mitigation. This study uses
        GRACE/GRACE-FO satellite data to identify groundwater storage
        change hotspots in mainland China over the past two decades,
        employing Pettitt-test and temporal stability analyses. To
        ensure reliability, we cross-validated the GRACE/GRACE-FO-
        derived groundwater storage against Watergap Global Hydrological
        Model and available well records, the correlation coefficient
        distribution is 0.76{\textendash}0.88. The hotspots are
        categorized into loss (I, II, III) and gain (IV, V) categories.
        The severity of both gain and loss conditions increases with the
        level. Additionally, the study quantifies the contributions of
        natural and anthropogenic factors by integrating climatic and
        socio-economic variables. The results indicate that loss
        hotspots dominate in North China, Loess Plateau, Northwest
        China, Northeast China, and Qinghai-Tibet Plateau. In the
        Qinghai-Tibet Plateau region, the combined proportion of Level
        I, II, and III loss hotspots exceeds 60\%, whereas in other
        regions, the combined proportion of these loss hotspots is over
        75\%. In contrast, surplus hotspots are prevalent in South
        China, Ch-Yu region, Middle-Lower Yangtze River, and Yun-Gui
        Plateau, where level IV and V gain hotspots exceed 60\%.
        Groundwater changes in the Qinghai-Tibet Plateau and Loess
        Plateau are primarily influenced by land use, whereas economic
        factors play a more significant role in other regions. This
        study offers valuable insights into regional groundwater changes
        across China and provides a scientific foundation for effective
        water resource management.}",
