Fig. 4: The relative importance of the response ratio (lnRR) of influencing factors in affecting the lnRR of particulate and mineral-associated organic carbon (POC and MAOC, a and b) temperature sensitivity (Q10) derived by Random Forest model.

POC or MAOC r1620/(2850 + 2920): ratio of peak value at 1620 cm−1 to the sum of peak values at 2850 cm−1 and 2920 cm−1 from FTIR spectrum of POC or MAOC; POC B: the fundamental microbial respiration rate of unit OC at 0 °C of POC; RB: root biomass. n = 12, where the POC or MAOC r1620/(2850 + 2920), POC or MAOC bacterial and fungal Shannon parameters represent composite samples of the sampling sites, and the other parameters represent the mean values of replicate samples from the sampling sites.
