- Intervention effect Tree species mixing management significantly enhanced the overall functional efficiency of the ecosystem in Cunninghamia lanceolata plantations.
- Intervention effect Tree species mixing improved stand features.
- Intervention effect Tree species mixing reduced competition intensity among trees.
- Intervention effect Tree species mixing increased the α-diversity of each vegetation layer.
- Intervention effect Tree species mixing decreased the β-diversity of each vegetation layer.
- Intervention effect Tree species mixing increased litter layer thickness and soil available phosphorus content, with the magnitude varying across management stages.
- Observation Soil bacterial α-diversity (Shannon) was reduced by 2.7%.
- Observation The soil core microbial community showed an enrichment of oligotrophic bacteria (Acidibacter, +29.1%).
- Observation The soil core microbial community showed an increase in core fungal taxa.
- Mechanism The authors attribute to the microbial shift enhanced decomposition of organic matter (litter thickness +27.8%).
- Mechanism The authors attribute to the microbial shift enhanced transformation of nutrients (available nitrogen +32.6%).
- Mechanism Structural equation modeling indicated that tree species mixing mainly drives soil carbon accumulation via the tree diversity-core bacterial community-microbial biomass pathway.
