The pie chart represents the location of the critical zone units considered in this study. The different colors within the pie charts represent the bedrock concentrations of the elements. Each critical zone unit has a meteorological observation station at the center with a radius of 20 km. the net primary productivity (NPP, g Cm-2 yr-1) is divided into five levels, i.e., I: 0.00–319.83, II: 319.83–513.40, III: 513.40–740.65, VI: 740.65–1060.48, V: > 1060.48.
