英文摘要Global warming and vegetation greening profoundly affect the hydrological cycle worldwide. Investigating the impact of climate change and vegetation dynamics on streamflow components, especially baseflow, is vital for understanding the hydrological response to ecosystem changes. In this study, the baseflow separation method with the highest stability and accuracy was conducted to extract baseflow in 24 catchments of the Yellow River Basin (YRB). Eight factors including phenology metrics were adopted for analyzing the spatiotemporal changes in vegetation dynamics and climate change from 1982 to 2020. Furthermore, methods that account for nonlinearity, temporal autocorrelation, and spatial heterogeneity were applied to assess the contribution of factors to baseflow and baseflow index (BFI). Results indicated that: (1) The start of the growing season (SOS) advanced, the growing season length (GSL) extended, the mean NDVI during the growing season (NDVIGS), temperature (TEM), and evapotranspiration (ET) increased while the end of the growing season (EOS) delayed, and precipitation (PRE) and soil moisture (VSW) decreased. These changes were more pronounced from the upper to the middle reaches. (2) The baseflow at the outlet of the research area decreased by -3.98 +/- 3.34 m3/s per year while the BFI increased by (9.15 +/- 3.91) x 10-4 per year, with a corresponding different distribution dominated by changes in PRE and vegetation dynamics. (3) TEM, GSL, NDVIGS, SOS, and VSW were responsible for the magnitude of decreased baseflow with contributions of 18.38 %, 18.13 %, 17.27 %, 14.29 %, and 13.63 %, respectively; SOS and TEM drove the baseflow increase in the upper reaches while TEM, VSW, NDVIGS, and PRE drove the baseflow decrease in the middle reaches, revealing the indispensable effect of vegetation dynamics on the baseflow changes. This study could improve the understanding of the determinants of hydrological changes and provide scientific guidance for rational catchment management.
