Research on Comparison and Optimization Strategy of Carbon Fixing Capacity of Mine Ecological Restoration Technology under the Target of Carbon Neutralization

Mine ecosystem, as one of the largest carbon “pools” in the world, is of great significance for carbon fixation and sink enhancement. Under the background of the “carbon neutrality” strategy, in order to strengthen the carbon sequestration in mining areas and achieve the goal of “carbon neutrality”, the mechanism, evaluation methods and technical measures of carbon sequestration in mining areas were systematically sorted out, aiming at providing a scientific basis for carbon sequestration and exchange in mining areas. Firstly, this paper analyzes the international situation of mine restoration, summarizes the mechanism of carbon sequestration in mines and the calculation and evaluation methods of carbon sink, and points out the application of four basic measures of carbon sequestration in mining areas, such as mine waste treatment, landform reconstruction, soil reconstruction and vegetation restoration, as well as the application of collaborative restoration technology and intelligent monitoring in enhancing carbon sink in mining areas. At the same time, in view of the shortage of current carbon sink technology, the promotion strategies of multi-technology collaborative repair and intelligent repair is prospected. It is expected to provide reference for perfecting the technical system, promoting the perfection of carbon sink market and interdisciplinary research, realizing negative emissions in mining areas and realizing the transformation from "carbon source" to "carbon sink".
