^†

MAP, mean annual precipitation; MAT, mean annual temperature; TN, soil total nitrogen content; TC, soil total carbon content. MAP and MAT are cited from Shen et al. [25]. Soil samples are collected at 0–10 cm depth.

^‡

Means with different lowercase letters differ significantly among elevations (P<0.05).
