基于CiteSpace的甲烷管控技术研究进展和热点分析

Research advances and hotspot of methane management and control technology based on CiteSpace analysis

  • 摘要: 为了更好地掌握国内外甲烷管控技术研究的发展动态和趋势,通过文献计量分析方法,从中国知网(CNKI)和Web of Science数据库中分别收集了2011—2021年间的24 358篇和50 020篇文献,从文献的发文数量、研究力量、研究热点等方面对甲烷管控技术研究进展进行了总结分析。结果表明:2011—2021年甲烷管控技术研究的发文数量总体增长了2.2倍;中国和美国发文数量大幅领先于其他国家和地区,占据甲烷管控研究领域的第一梯队位置;甲烷管控技术研究主要围绕煤炭、油气、农业、废弃物处置等行业领域开展,其中煤矿瓦斯的穿层钻孔、卸压增透、厌氧发酵、产甲烷菌等关键词具有较高的出现频次;生物燃料产甲烷、微生物种间电子转移、甲烷重整将是甲烷管控领域的前沿科学问题,各国研究的侧重点呈现多元化。研究结果揭示了甲烷管控研究的知识基础、热点及前沿趋势,可为开展甲烷管控技术研究和支撑碳减排管理提供理论和实践参考。

     

    Abstract: To keep track of the worldwide research trends of methane management and control technology, 24 358 and 50 020 articles from 2011 to 2021 were selected from China National Knowledge Infrastructure (CNKI) and Web of Science databases, respectively. Through bibliometric analysis, the research progress of methane management and control technology was summarized and analyzed from the aspects of the quantity of published papers, research teams and research hotspots. The results show that the number of articles on methane control technology research has increased by 2.2 times. The number of published papers in China and the United States significantly exceeds other countries and regions, occupying the first-tier in the related field. The research on methane management and control technology is mainly focused on the fields of coal, oil and gas, agriculture, waste disposal and other industries. The keywords such as cross-layer borehole, pressure relief and antireflection, anaerobic fermentation and methanogens appear in a higher frequency. Prospectively, methane production from biofuels, interspecies electron transfer, and methane reforming would become the frontier issues in the future. In general, there are diversified trends in the research interest of various countries. This article reveals the knowledge basis, hotspots and frontier trends of methane management and control research, providing theoretical and practical reference for carrying out research on methane management and control technology and supporting the management of carbon emission reduction.
