- •
Soil P biogeochemistry across 7 altitudes with 6 vegetation types was studied.
- •
The TP stock was higher in 3838–4235 m than that in 2032–3614 m.
- •
Labile P showed a parabolic trend with an altitude that was inverse with HCl-Pi.
- •
Variation of labile P along the gradient was mainly impacted by soil pH and vegetation type.
- •
Temperature is an additional factor affecting change of labile P in 3060–4235 m.
