Note: Capital letters indicate that there are significant differences (P < 0.05) between vegetation types under the same soil layer (n = 12). The error is the standard error.

Table 3. Two-factor ANOVA analysis was used to test the differences in soil organic carbon components (MBC, EOC, POC, SOC) and enzyme activities (amylase, catalase, urease, and invertase). VT: vegetation type, SD: soil depth.
