The root biomass distribution in alpine ecosystems (alpine meadow, alpine steppe, desert
grassland and alpine desert) was investigated along a transect on the northern Tibetan
Plateau in 2009. The results showed that roots were mainly concentrated in the 0–20 cm
layer, and root biomass decreased exponentially with increasing soil depth. Root biomass
was estimated to be 1,381.41±245.29 gm− 2 in the top 20 cm soil, accounting for 85% of the
total root biomass. The distribution pattern of the root biomass proportion along the soil …
