Table 2 Analytical results of the factors affecting Rs, Rh, Ra, and soil labile organic carbon. In the table, asterisk represents statistical significance, in which *P < 0.05, **P < 0.01, and ***P < 0.001. Rs, soil respiration; Rh, heterotrophic respiration; Ra, autotrophic respiration; SOC, soil organic carbon; DOC, soil dissolved organic carbon; MBC, microbial biomass carbon; LFOC, light fraction organic carbon; ROC, readily oxidized carbon
