GB/T 43935-2024 in English

Standard Background and Technical Evolution

This standard was jointly compiled by the Ministry of Natural Resources and 8 scientific research institutions, integrating the technical requirements of 21 current national standards and 14 industry standards. Compared with earlier standards such as TD/T 1036-2013, 8 innovative indicators such as ecosystem service function evaluation and carbon sink measurement were added, reflecting the technical upgrade from single land reclamation to comprehensive management.

Interpretation of core content

Key technical points

1. Principles of monitoring point layout

Adopt "point-line-surface" three-dimensional network layout:

• Intensified point layout in geologically sensitive areas (spacing ≤500m)
• Mandatory monitoring in basic farmland protection areas
• The proportion of reference ecosystem plots ≥15%

2. Innovative evaluation methods

Implementation suggestions

1. Differentiated monitoring schemes: Metal mines focus on monitoring heavy metal migration, while coal mines focus on hydrological monitoring of subsidence areas
2. Multi-source data fusion: Combine InSAR remote sensing and ground sensors to build a space-ground integrated monitoring network
3. Dynamic adjustment mechanism: Optimize monitoring indicators every 3 years, and establish a PDCA cycle with reference to ISO 14001

Application value of standards

After implementation, it is expected to increase the acceptance rate of reclamation by 30%, reduce the cost of later management by 45%, and provide a standardized measurement basis for carbon sink trading. The application of a demonstration project in Hebei shows that the recovery rate of ecosystem service value has reached 82%.
