Urban forest plant diversity affects soil organic carbon by regulating functional genes in Nanning

Key Points

• Soil organic carbon levels increase with diverse plant species in urban forests, which helps in carbon cycling.
• Functional genes linked to carbon processing are positively influenced by higher plant diversity, indicating specific ecological interactions.
• Observational analysis of urban forests in Nanning shows a clear relationship between plant diversity and soil health metrics.
• Understanding these interactions may enable better urban planning and environmental conservation strategies moving forward.
