Introduction
1. Standard Overview
The National Standard of the People's Republic of China GB/T 43933-2024 "Technical Specifications for Land Reclamation and Ecological Restoration of Metal Mines" was issued in 2024. It aims to guide the scientific restoration of geological environmental damage, land damage and vegetation damage caused by metal mines during the mining process, so as to achieve the safety and stability of the mine geological environment and the restoration and improvement of the ecosystem function.

3. Implementation suggestions
Case study: Ecological restoration practice of a metal mine
When implementing land reclamation and ecological restoration of metal mines, it is recommended to take the following steps:
- Basic investigation and problem identification: Comprehensively understand the natural conditions, socio-economic conditions and geological environment status of the mining area.
- Reference ecosystem establishment: Set restoration goals based on the characteristics and functions of the surrounding undamaged ecosystem.
- Soil reconstruction and vegetation reconstruction: Give priority to the use of local plants, and combine spraying, vegetation blankets and other technologies to improve survival rates.
- Landscape construction and function improvement: Enhance biodiversity connectivity through wetland reconstruction and ecological corridor design.
4. Analysis of technological evolution
In recent years, mine land reclamation and ecological restoration technologies have gradually developed from single engineering measures to systematic and intelligent directions. The application of new technologies such as geographic information systems (GIS) has significantly improved the accuracy and implementation efficiency of restoration plans. In addition, the application of bioengineering technology in vegetation reconstruction has also achieved remarkable results, especially in the restoration of heavy metal contaminated sites.
