Fig. 6From: Effects of stand density on soil respiration and labile organic carbon in different aged Larix principis-rupprechtii plantationsCorrelations between the Rs, Rh, Ra, and the SOC and soil labile organic carbon for different aged stands. 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, heterotrophic respiration; Ra, autotrophic respiration. 27a, 27-year-old stand; 36a, 36-year-old stand; 48a, 48-year-old standBack to article page
