Other claims from this paper (17)
- Observation Alopecurus aequalis raised soil shear strength to 28.83 kPa, compared with 16.73 kPa for bare soil.
- Observation Hedyotis chrysotricha raised soil shear strength to 42.53 kPa, compared with 16.73 kPa for bare soil.
- Observation Dicranopteris dichotoma had the highest stabilization efficiency, 232.32% higher than bare soil in soil shear strength.
- Association Root architecture significantly influenced terrace wall stability (path coefficient 0.56).
- Association Root additional cohesion significantly influenced terrace wall stability (path coefficient 0.29).
- Association Soil aggregate stability significantly influenced terrace wall stability (path coefficient 0.24).
- Association Soil moisture content significantly reduced terrace wall stability (path coefficient -0.37).
- Association Root architecture indirectly improved soil aggregate stability (path coefficient 0.58).
- Association Root architecture indirectly improved root additional cohesion (path coefficient 0.78).
- Observation Topological index and fractal dimension were key contributors to root architecture.
- Observation Root architecture emerged as the primary stabilizer for terrace walls.
- Observation Fine roots under 0.9 mm diameter predominantly contributed to root tensile strength.
- Observation High soil moisture content significantly reduced terrace wall stability.
- Recommendation Selecting species with a high topological index (for example D. dichotoma) is recommended to enhance root-soil interlocking.
- Recommendation Promoting fine roots under 0.9 mm diameter is recommended to increase tensile strength.
- Recommendation Effective drainage systems should be implemented to mitigate moisture-induced destabilization.
- Recommendation Soil aggregate stability should be preserved for terrace wall stability.
