XS: Xanthoceras sorbifolia ; HR: Hippophae rhamnoides ; CK:Caragana korshinskii ; GL: Grassland. 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 (microbial biomass carbon,
MBC; easily oxidized carbon, EOC; particulate organic carbon, POC; soil
organic carbon, SOC) and enzyme activities (amylase; catalase; urease;
invertase). VT: vegetation type, SD: soil depth.
