     abstract = "{Net primary productivity (NPP) is an important parameter reflecting
        vegetation growth, and water is one of the necessary factors for
        vegetation growth. Investigating the mutual influence between
        NPP and water is significant for ensuring the stable development
        of the ecological environment. This study focuses on the Yangtze
        River Basin (YRB) as the research area, and based on medium-
        resolution imaging spectrometer (MODIS) data, climate data, and
        gravity recovery and climate experiment (GRACE) data, the
        spatiotemporal evolution characteristics of vegetation NPP and
        terrestrial water storage (TWS) in the YRB from 2000 to 2022 are
        explored and analyzes the mutual influence of NPP with climate
        factors and TWS. The results show that vegetation NPP (4.10
        gC{\textperiodcentered}m$^{‑2}${\textperiodcentered}a$^{‑1}$)
        and TWS (0.55 mm) in the YRB have exhibited an increasing trend
        from 2000 to 2022, with a strong correlation between the two,
        which is related to recent environmental policies. Analysis of
        the impact of climate factors on NPP reveals that temperature
        and TWS significantly positively impact NPP changes.
        Furthermore, comparisons between NPP and TWS indicate that
        changes in TWS substantially promote plant growth. In addition,
        the comparison between NPP and TWS indicates that changes in TWS
        have an important promoting effect on plant growth. Surface
        water (SWS) and soil water (SM) have a significant promoting
        effect on plant growth, but with a strong lag, while the
        consumption of groundwater (GWS) has been promoting plant growth
        without significant lag.}",
