Redundancy analysis (RDA) to determine the effects of the selected soil organic carbon factor (black arrows) on soil respiration (red arrows). SOC, soil organic carbon; DOC, soil dissolved organic carbon; MBC, microbial biomass carbon; LFOC, light fraction organic carbon; ROC, readily oxidized carbon; Rs, soil respiration; Rh and heterotrophic respiration; Ra, autotrophic respiration. 27a, 27-year-old stand; 36a, 36-year-old stand; 48a, 48-year-old stand
