采用 CiteSpace 软件对近 22 年来中国知网(China national knowledge infrastructure，CNKI)和 Web of Science(WOS)数据库中收录的有关蓝藻厌氧处理方向的文献，进行了年度发文量、作者、机构、国家、关键词共现、突现、聚类等可视化分析。通过人工剔除不相关文献，共筛选出339篇有效文献。蓝藻厌氧处理研究从2007年开始，但近几年学者对该领域关注度不高，该领域进入新的瓶颈期。其中，中国和美国学者是此领域重要的研究力量。中国是发文量最多的国家，中国科学院是发文量最多的机构;研究热点集中于蓝藻的厌氧消化、产沼气潜力、资源化利用、预处理、藻毒素的降解、与其他物质共消化以及用微藻为原料生产可再生能源。认为在双碳目标的大背景下，蓝藻厌氧处理有广阔的发展前景，厌氧发酵产酸很可能成为新的研究热点。通过可视化的方式解析了蓝藻厌氧处理研究发展态势，提出了未来重点研究方向，可为水体富营养化控制与可持续发展的提供重要的理论基础。
Bibliometric and Visual Analysis of Cyanobacteria Anaerobic Treatment Research Literature Based on Citespace
In this paper,CiteSpace software was used to analyze the literature on the anaerobic treatment of cyanobacteria in the database of Chi-na national knowledge infrastructure(CNKI)and Web of Science(WOS)in the past 22 years.Visual analysis such as annual publication a-nalysis,author analysis,institutional analysis,national analysis,keyword co-occurrence,burst,and cluster analysis.Finally,a total of 339 valid literatures were screened out by manually eliminating irrelevant literatures.The research on anaerobic treatment of cyanobacteria has flour-ished since 2007,but in recent years,scholars have not paid much attention to this field,and this field has entered a new bottleneck period.A-mong them,Chinese and American scholars are important research forces in this field;China is the country with the largest number of publica-tions,and the Chinese Academy of Sciences is the institution with the largest number of publications.The research focuses on anaerobic diges-tion of cyanobacteria,biogas production potential,resource utilization,pretreatment,degradation of algal toxins,co-digestion with other sub-stances,and production of renewable energy from microalgae.Under the background of double carbon target,anaerobic treatment of cyanobac-teria has broad development prospects,and anaerobic fermentation to produce volatile fatty acid is likely to become a new research hotspot.In this paper,the development trend of cyanobacteria anaerobic treatment is analyzed by visualization,and the key research directions in the future are put forward,which can provide an important theoretical basis for the control of water pollutants and the sustainable development.
