Note: Values are mean ± 1 s.e.m., Means within a column with different lowercase letters are significantly different from others at the same depth (P < 0.05). Means within a column with different capital letters are significantly different from others at the same damage level (P < 0.05). MBC, microbial biomass carbon; WSOC, water-soluble organic carbon; ROC, readily oxidizable carbon; TOC, total soil carbon concentration.
