Fig. 5From: Effects of stand density on soil respiration and labile organic carbon in different aged Larix principis-rupprechtii plantationsVariation of SOC and soil labile organic carbon with stand density in different aged stands. Error bars show the standard deviation (SD). Shaded areas represent the confidence intervals. SOC, soil organic carbon; DOC, soil dissolved organic carbon; MBC, microbial biomass carbon; LFOC, light fraction organic carbon; ROC, readily oxidized carbon. 27a, 27-year-old stand; 36a, 36-year-old stand; 48a, 48-year-old standBack to article page
