Relationship between bacterial community composition and soil properties under different soil types. Structural equation model in NS (a), HS (b), DS (c) and PS (d). Random forest analysis in NS (e), HS (f), DS (g) and PS (h). CO2: carbon dioxide emissions; IOC: Insoluble organic carbon; ION: Insoluble organic nitrogen; NO3−: nitrate nitrogen; NH4+: ammonium nitrogen; C/N: IOC/ION; BCN: Bacterial copy number.
