        (LMRB), the spatio-temporal differentiation of total water
        resources and the natural-human influence need to be clarified.
        This work investigated LMRB's terrestrial water storage anomaly
        (TWSA) and its spatio-temporal dynamics during
        2002{\textendash}2020. Considering the effects of natural
        factors and human activities, the respective contributions of
        climate variability and human activities to terrestrial water
        storage change (TWSC) were separated. Results showed that: (1)
        LMRB's TWSA decreased by 0.3158 cm/a. (2) TWSA showed a gradual
        increase in distribution from southwest of MRB to middle LMRB
        and from northeast of LRB to middle LMRB. TWSA positively
        changed in Myanmar while slightly changed in Laos and China. It
        negatively changed in Vietnam, Thailand and Cambodia. (3) TWSA
        components decreased in a descending order of soil moisture,
        groundwater and precipitation. (4) Natural factors had a
        substantial and spatial differentiated influence on TWSA over
        the LMRB. (5) Climate variability contributed 79\% of TWSC in
        the LMRB while human activities contributed 21\% with an
        increasing impact after 2008. The TWSC of upstream basin
        countries was found to be controlled by climate variability
        while Vietnam and Cambodia's TWSC has been controlled by human
        activities since 2012.}",
