Current status and prospects of research on MICP: a bibliometric analysis

摘要:

目的 系统梳理微生物诱导碳酸钙沉淀(microbially induced calcium carbonate precipitation, MICP)领域近25年的研究动态，通过文献计量学方法揭示其发展趋势、研究热点及学术影响力分布，为相关研究人员提供数据参考，并对未来MICP的重点研究方向提出建议。方法 基于Web of Science核心数据库筛选出1999-2024年的1 947篇文献，综合运用文献计量学与CiteSpace可视化分析工具，对发文量、作者、国家、机构及关键词等进行量化统计，结合时间序列与网络图谱解析该领域发展脉络。结果 MICP领域年度发文量持续增长，中国以显著贡献成为主导出版国，发文量占全球总量的47.71%；南洋理工大学、中国科学院、东南大学和重庆大学在发文量及引用频次等方面展现较强的学术影响力；研究热点集中于土体改良、自愈合混凝土及生物修复等方面，关键词聚类表明环境岩土工程与生物材料应用为交叉前沿。结论 MICP研究已形成多学科融合的快速发展态势，中国在该领域处于全球领先地位。未来需强化生物-矿物相互作用机理的基础研究，推动MICP技术在环境修复与智能材料等新兴场景的应用突破，同时关注绿色可持续工艺的研发，以拓展其在碳中和与生态工程中的实践价值。

Abstract:

Objective This study systematically reviews the research trends in microbially induced calcium carbonate precipitation (MICP) over the past 25 years. Through bibliometric analysis, we aim to elucidate the developmental trajectory, research hotspots, and academic impact distribution of MICP, offering data-driven insights for researchers and proposing strategic priorities for future studies.Methods A comprehensive dataset of 1 947 publications was extracted from the Web of Science Core Collection (1999-2024). Bibliometric analysis and CiteSpace visualization tools were employed to quantify publication volume, authorship patterns, country/institutional contributions, and keywords dynamics. Time-series analysis and network mapping were integrated to decode the evolutionary pathways and interdisciplinary frontiers of the field.Results Annual MICP publications exhibit sustained growth, with China emerging as the dominant contributor, accounting for 47.71% of global output. Leading institutions such as Nanyang Technological University, Chinese Academy of Sciences, Southeast University, and Chongqing University demonstrate strong academic influence through high publication output and citation frequency. The research hotspots are primarily concentrated in soil improvement, self-healing concrete, and bioremediation. Keywords clustering analysis reveals emerging interdisciplinary frontiers at the intersection of environmental geotechnics and biomaterials applications.Conclusion MICP research has entered a phase of rapid multidisciplinary integration, with China leading global advancements. Future efforts should prioritize fundamental studies on bio-mineral interaction mechanisms, accelerate MICP applications in environmental remediation and smart materials, and develop green, sustainable processes to enhance its role in carbon neutrality and ecological engineering.
