Soil microbial biomass stoichiometry homeostasis is essential for microorganism survival and ecosystem stability. Despite its importance, research on soil in Natural World Heritage Sites (NWHS) lacking. This study analyzed ecological surface (0–20 cm) subsurface (20–40 soils across various vegetation types Fanjing Mountain, an NWHS China. The objective was to explore relation identify key influencing factors. Results indicated that higher than 5 types, mirroring nutrient but contrasting enzyme stoichiometry. Vector length (VL) suggests C limitation all while vector angle (VA) shows P of certain N types. Random forest analysis revealed the carbon-nitrogen ratio (MB C/N) mainly contributed by C/N (14.11 %), SOC (12.31 pH (10.52 NH4+-N, SWC, NO3--N soil, (15.74 altitude, SOC, whereas carbon-phosphorus C/P), altitude (12.16 SWC (9.86 AP were main contributing factors (10.49 C/P, TP. provides insights into stoichiometry, homeostasis, limitations aiding balance management NWHS.
