Overview maps of study regions. a Global map of closed basins and locations of closed basins of the Qilian Mountains. The shaded parts show global drylands where aridity indexes are lower than 0.65 and the gray bars indicate global closed basins where there are no outflows to the oceans. b Detailed map of closed basins of the Qilian Mountains and locations of sampling sites. The Roman numerals represent various closed drainage basins, I: Shiyang River drainage basin, II: Heihe River drainage basin, III: Shule River drainage basin, IV: Qaidam drainage basin; V: Qinghai Lake drainage basin
