Carbon neutral path planning and carbon sink accounting method for open pit mining
露天矿区碳中和路径规划与碳汇核算方法

摘要

露天矿区在资源开发过程中排放大量温室气体，实现碳中和已成为可持续发展的关键目标。本文以矿区碳中和路径规划为主线，构建低碳能源替代、绿色工艺优化与生态修复协同推进的系统框架。在路径设计中引入碳排放清单与减排情景模拟，形成可操作的分阶段实施方案。针对碳汇核算，提出基于矿区植被恢复、土壤碳储量与区域生态系统功能的综合测算方法，实现碳排与碳汇的平衡评估。研究表明，该方法不仅能提高碳中和路径的科学性与可行性，还为矿区绿色转型提供定量化依据。

Abstract

Open-pit mining areas emit substantial greenhouse gases during resource extraction, making carbon neutrality a critical objective for sustainable development. This study establishes a systematic framework integrating low-carbon energy substitution, green process optimization, and ecological restoration to guide carbon-neutral pathway planning in mining regions. The design incorporates carbon emission inventories and emission reduction scenario simulations to develop actionable phased implementation plans. For carbon sink accounting, we propose a comprehensive methodology that evaluates vegetation recovery, soil carbon storage, and regional ecosystem functions to achieve balanced carbon emission-sink assessments. Research demonstrates that this approach not only enhances the scientific rigor and feasibility of carbon neutrality pathways but also provides quantitative evidence for green transformation in mining areas.
