Three-Dimensional Vegetation Mat: Principles, Installation Process, and Applications

Working Principle

The three-dimensional vegetation mat is a multi-layered polymer mesh with structural strength and flexibility. When installed on slopes, it creates an optimal environment for plant growth by:

1. Erosion Control: Preventing soil loss and reducing water runoff impact.

2. Vegetation Support: Providing anchorage for seeds while promoting root development. Plant roots synergize with the mesh to reinforce slope stability and achieve dual-purpose protection/greening.

Installation Procedure

1. Slope Preparation

• Clear debris, rocks, and weeds; grade to ≤1:1.5 slope ratio.

• Install drainage systems (e.g., intercept ditches) to prevent waterlogging.

2. Mat Deployment

• Roll mats top-to-bottom, ensuring full contact with slope (no wrinkles/sagging).

• Secure at crest/toe (embed ≥30cm) and mid-slope (anchors every 1–1.5m).

• Overlap adjacent mats (≥10cm) and fasten with wire/nylon ties.

3. Hydroseeding

• Spray seed-fiber slurry (10–20g/m²) using drought-resistant species (e.g., Bermuda grass, ryegrass) mixed with fertilizers/soil amendments.

4. Geotextile Covering

• Lay non-woven fabric to retain moisture and protect seedlings; remove after germination.

5. Maintenance

• Water 1–2x daily initially, tapering as plants establish.

• Fertilize bimonthly (10–15g/m² composite fertilizer).

• Prune regularly and monitor for pests/diseases.

Advantages

✔ Superior Erosion Resistance – Withstands heavy rainfall and soil displacement.
✔ Rapid Greening – Accelerates vegetation coverage for immediate ecological benefits.
✔ Cost-Effective – Simple installation with minimal equipment.
✔ Durability – 10–20 year service life through UV/chemical resistance.

Applications

• Transportation Infrastructure: Highway/railway embankments (stabilization + aesthetics).

• Mine Rehabilitation: Restores vegetation on post-mining slopes.

• Riparian Protection: Prevents riverbank erosion while improving water quality.

• Engineered Slopes: Landfill caps, construction sites, etc.
