Path analysis among habitat factors, non-tree vegetation community structure, and specific leaf area. “*” indicate P < 0.05. “**” indicate P < 0.01. ALT (Altitude), SD (Species diversity), VC (Vegetation coverage), STN (Soil total nitrogen), SLA (Specific leaf area). In the path diagram, the standardized beta coefficient represented the total effect. The table below the diagram presented the direct and indirect effects among various factors within different vegetation types.
