     abstract = "{Mountains represent important water towers and thus are the primary
        water suppliers for downstream areas. However, divergent trends
        in terrestrial water storage (TWS) in water towers and their
        driving factors have not been clarified. This study investigated
        water tower units (WTUs) in Northwest China (NWC) and used
        GRACE/GRACE FO and multi source remote sensing data to analyze
        the spatiotemporal changes in TWS over the past 20 years. Based
        on correlation analysis and structural equation modeling, the
        effects of precipitation (PRE), evapotranspiration (ET),
        temperature (TEM) and NDVI on TWS were revealed. The results
        showed that TWS decreased in the WTUs of the Junggar and Ili
        River basins while increasing in the Qaidam and Yellow River
        basins. Glacier retreat and snowmelt were the components that
        contributed the most to TWS changes in the WTUs of the Tarim,
        Junggar, Ili River, and Irtysh River basins, while lake
        expansion, groundwater, and soil moisture contributed the most
        in the remaining WTUs. Additionally, the dominant roles of
        climate and vegetation factors on TWS changes varied
        significantly among the WTUs. For example, glacial retreat and
        increased ET caused by climate warming and vegetation greening
        exacerbated the TWS reductions in WTUs of the Junggar and Ili
        River basins, whereas vegetation greening dominated TWS changes
        within the Yellow River basin by affecting groundwater storage
        and soil moisture. These findings are crucial for understanding
        changes in the hydrological cycle of water towers and optimizing
        future watershed water resource management strategies.}",
