Why is preventing erosion important in land reclamation?

Preventing erosion is crucial in land reclamation because it helps to maintain soil stability and health. When erosion occurs, it can lead to the loss of topsoil, which is rich in nutrients essential for plant growth. This nutrient-rich layer supports vegetation regeneration, which is vital for restoring the ecosystem after mining activities. Additionally, stable soil prevents further erosion, thereby protecting the newly restored landscape and ensuring that the plants can establish roots and contribute to overall soil health.

In contrast, increasing mining output, reducing traffic in reclamation areas, and lowering operational costs, while important in other contexts, do not directly address the long-term ecological goals of land reclamation. The focus after mining operations is on creating a sustainable environment, and preventing erosion fundamentally supports this goal by ensuring the land can recover effectively and maintain its ecological integrity.
