Overview

Meta-analysis reveals enhanced soil organic carbon stabilization via aggregate stability in restored karst landscapes, highlighting the role of soil structural recovery.

Key Points

  • To evaluate how vegetation restoration types and environmental conditions alter aggregate-size distribution, aggregate stability, and soil organic carbon accumulation in degraded karst landscapes.
  • Conducted a meta-analysis of 213 paired observations compiled from 57 studies in southwest China.
  • Assessed cropland conversion into abandoned land, cash crops, grassland, shrubland, and forest.
  • Applied piecewise structural equation modeling to identify causal pathways connecting environmental drivers and aggregate stability to soil organic carbon response.
  • Vegetation restoration shifted aggregate-size distribution from smaller (< 1 mm) to larger (> 1 mm) fractions and enhanced soil organic carbon, with the largest increases occurring under forest and shrubland.
  • The 2–5 mm aggregate fraction demonstrated the most consistent relative importance for soil organic carbon across restoration types.
  • Piecewise structural equation modeling confirmed aggregate stability as a key mediating pathway driving soil organic carbon accumulation.
