Subfigures (a, b, d, e) showcase the spatial distribution of dominant drivers in regions experiencing groundwater quality deterioration from 2020 to 2050 under the four scenarios; Here, a corresponds to Scenario I, b to Scenario II, d to Scenario III, and e to Scenario IV; Subfigure c displays the dominant drivers in regions experiencing groundwater quality improvement from 2020 to 2050 in Scenario II, and the insets in (a–e) presents the area ratios of regions with different dominant drivers over China; Subfigure f shows the contributions of each driver category to changes in the PGQ area ratio from 2020 to 2100 in China. Here, “C”, “E”, “L”, and “P” represent climate, exploitation, land use, and pollution drivers, respectively.
