A Bibliometric Study on the Restoration and Carbon Sink Potential of Damaged Ecosystem in Mining Area
[Objective]Mining activities have a detrimental impact on the environment,both in China and globally,leading to pollution,ecosystem damage,and risks to human health.The restoration and remedi-ation of damaged ecosystems in mining areas present significant challenges,particularly in the context of China's commitment to carbon neutrality.[Method]This study analyzed 914 literature published between 2010 and 2022,focusing on four key aspects of ecological restoration in mining areas:evaluation of dam-aged ecosystems,ecological restoration technology,carbon source/sink potential,and monitoring techno-logy.[Result]There had been a shift in the approach to restore damaged ecosystems in mining areas.Earlier emphasis on"engineering restoration"had given way to a more holistic approach known as"sys-tem ecological restoration".There was a transition from solely addressing fragmented and isolated areas to considering the restoration of the entire regional ecosystem.Additionally,study on the carbon source/sink in mining areas and the carbon cycle mechanisms of the regional environment is progressing.The applica-tion of big data technologies,such as remote sensing,played a significant role in advancing monitoring and evaluation systems for mining rehabilitation.The effectiveness of restoration efforts in degraded min-ing areas was influenced by various factors including improvements in laws and regulations,system con-trol systems,multi-disciplinary integration,and striking a balance between production and living ecology.[Conclusion]This study clarifies the current dilemmas and challenges in the research and application of damaged ecosystem restoration and carbon sequestration potential in mining areas and provides refer-ence for future ecological restoration management and monitoring and evaluation in mining areas.
