Fig. 3: Variations in potassium (K) density (g m–2) among plant organs across different vegetation types on the Tibetan Plateau.
From: High precipitation rates increase potassium density in plant communities in the Tibetan Plateau
The four values at the top of the picture represent the average K density of different organs, different lowercase letters indicate significant differences among the organs in each column at P < 0.05. Different color columns in the map represent K densities in different organs of different vegetation types (green: leaves, pink: branches, blue-violet: trunk, and brown: roots). Vegetation zoning is based on the dominant vegetation type with reference to vegetation types found in China. The XY coordinate system of the map is the projection coordinate system of WGS_1984_Albers. Dleaf: leaf K density (g m–2); Dbranch: branch K density (g m–2); Dtrunk: trunk K density (g m–2); Droot: root K density (g m–2). EBF evergreen broad–leaved forest, ECF evergreen coniferous forest, DBF deciduous broad–leaved forest, MF coniferous and broad–leaved mixed forest, EBS evergreen broad–leaved shrubs, ECS evergreen coniferous shrubs, DBS deciduous broad–leaved shrubs, AMG alpine meadow grassland, ATG alpine typical grassland, ADG alpine desert grassland.
