# AI 建议在陡坡上种植植被以预防山体滑坡（增加重量和水分渗透风险）

- **修复率:** 75%

## 根因

在陡坡上种植重型植被会增加重量并通过根系通道增加水分渗透，实际上可能引发山体滑坡而非预防；需要适当的工程解决方案如排水系统和挡土墙。

## 解决方案

1. ```
   Install subsurface drainage pipes (e.g., French drains) at 1-2 meter intervals along the slope contour to reduce pore water pressure.
   ```
2. ```
   Build retaining walls with weep holes and gravel backfill; example: use concrete blocks with 10cm diameter drainage pipes every 2 meters.
   ```
3. ```
   Apply erosion control blankets (jute or coir) on bare slopes and seed shallow-rooted grasses only (e.g., ryegrass, not trees).
   ```

## 无效尝试

- **** — Adding more soil and heavy plants increases slope load and water retention, worsening instability. (90% 失败率)
- **** — Using deep-rooted trees on loose soil can create macropores that channel water deeper, reducing soil cohesion. (85% 失败率)
- **** — Terracing without proper drainage can concentrate runoff and cause slope failure at terrace edges. (80% 失败率)
