为解析反硝化细菌的研究进展和动态,基于Web of Science核心数据库,使用VOSviewer、Citespace等工具,分析了 1990-2022年反硝化细菌领域研究概况和发展趋势.该领域经历起因、探索、发展三个过程;涉足国家较多但合作关系较弱,欧洲国家区域性合作较强且发文质量较高;中国虽起步晚但发展迅速,发文量多但影响力不够;核心作者中中国彭永臻院士发文最多;核心作者之间合作交流较少.关键词呈现出"工具—对象—方法"三种类型,当前的研究主要关注生物脱氮性能以及致力于提高污废水的脱氮效能.未来的研究更注重在氮氧化物的排放、新型反硝化细菌的筛选及反硝化菌剂的研制和应用、同步硝化反硝化研究以及硝酸盐氮的去除等方面的深化和扩展.
Research Status and Development Trend of Denitrifying Bacteria Based on Web of Science Database
In order to analyze the research progress and dynamics of denitrifying bacteria,we analyzed the research overview and development trend of denitrifying bacteria from 1990 to 2022 based on the core database of Web of Science,using tools such as VOSviewer and Citespace.The field has experienced three processes of origin,exploration and development.There are many countries involved but the cooperation is weak,among which the European countries have stronger regional cooperation and higher quality of publications;although China started late,it has developed rapidly,with a large number of publications but insufficient influence;among the core authors,academician Peng Yongzhen of China has published the most articles;and there is less cooperation and communication among the core authors.The keywords present three types of"tool-object-method",and the current research is mainly concerned with the performance of biological denitrification and dedicated to improving the denitrification efficiency of wastewater.Future research will pay more attention to the deepening and expansion of nitrogen oxide emission,the screening of new denitrifying bacteria,the development and application of denitrifying agents,research on simultaneous nitrification and denitrification,and removal of nitrate nitrogen.
