  1. Values are the mean ± standard error (n = 8). PF P. massoniana forest; MF coniferous and broadleaved mixed forest; BF monsoon evergreen broadleaved forest. Different lowercase letters indicate significant differences among three depths in the same forest (p < 0.05). Different capital letters indicate significant differences among three forest types of the same depth (p < 0.05)
