Three-Dimensional Vegetation Mat: Key Roles in Soil Reinforcement

1. Mechanical Reinforcement

• Slope Protection:

• The 3D mesh structure disperses hydraulic pressure, reducing surface erosion by 40-60% compared to bare slopes.

• Prevents soil particle displacement under wind/water forces through its 12-25cm deep cellular confinement.

• Erosion Control:

• Decelerates runoff velocity by 30-50%, increasing rainwater infiltration time.

• Traps sediments within mesh pockets, cutting sediment loss by 70-90% during storms.

2. Vegetation Enhancement

• Seedbed Function:

• Provides microclimate stability (humidity retention >20% higher than exposed soil).

• Shields seeds from 90%+ avian/insect predation.

• Nutrient Cycling:

• Reduces N/P/K leaching by 25-40% through organic debris accumulation.

• Root systems increase soil organic matter by 1.5-3% annually through biomass turnover.

3. Soil Structure Improvement

• Porosity Boost:

• Creates 15-30% more macropores, enhancing air/water permeability 2-fold.

• Facilitates root penetration to 1.5m depth vs. 0.8m in compacted soils.

• Compaction Prevention:

• Cushions surface pressure (reducing bulk density by 0.2-0.4 g/cm³).

• Root exudates bind soil aggregates, increasing shear strength 3-5 kPa.
