Effect of land use type on (a) soil microbial biomass carbon content, (b) soil microbial biomass nitrogen content.
Values represent the mean of three replicates. Lower case letters: significant differences (P < 0.05) at different land use patterns in the same soil depth. Superscript letters: significant differences (P < 0.05) at different soil depths in the same land use pattern.

Correlation analysis of soil nutrients and soil microbial biomass carbon, soil microbial biomass nitrogen.
Note: *** indicates p < 0.001. ** indicates p < 0.01. * indicates p < 0.05. The color depth and circle size reflect the size of the correlation coefficient.

Note:Arrows represent hypothesized causal directions, with the numbers next to the arrows indicating the strength of standardized path coefficients. Green arrows indicate positive relationships, while red arrows denote negative relationships. Only statistically significant relationships are shown (* P < 0.05, ** P < 0.01, *** P < 0.001). The percentage below the ellipses represents the proportion of variance in MBC and MBN explained by the model.
