基于CNKI数据库的人工湿地文献计量分析

人工湿地是污水处理过程中重要的生态技术之一。了解人工湿地的发展过程和研究热点对于今后人工湿地的研究工作具有重要意义。本文使用文献计量学方法,自CNKI数据库采集数据,通过Citespace软件,从刊文数量、机构、主要作者、研究热点等方面对人工湿地研究进行可视化分析。结果表明：1987-2019年我国人工湿地的研究可以分为三个阶段,分别为起步阶段1987-2000年、快速发展阶段2001-2010年、稳定发展阶段2011-2019年。国家自然科学基金委是人工湿地研究的主要基金提供者,同济大学、东南大学和中国科学院水生生物研究所是发文量最多的学术机构,吴振斌等10名学者发表文章数占总发文量的5.5%,国内各机构及学者之间均有较为紧密的联系,研究热点体现在处理河流和污水处理厂尾水、工艺组合、植物耐寒和根系研究、发掘新兴基质等。本文提出了今后的研究方向为人工湿地生物膜理论的丰富、堵塞和冬季高效运行技术的工程化应用、人工湿地设计和运行管理维护的标准化等。

Bibliometric Analysis of Constructed Wetlands Based on the CNKI Database

Constructed wetland is one of the important ecological technologies in sewage treatment. Understanding the development process and research hotspots is of great significance to the future research of constructed wetland. This paper used bibliometric method and CiteSpace software to visually analyze the constructed wetlands in China. The data were collected from CNKI database and analyzed from the number of research papers published, institutions, main authors and research hotspots. The results showed that the research of constructed wetlands in China from 1987 to 2019 can be divided into three stages, namely, the initial stage of 1987-2000, the rapid development stage of 2001-2010, and the stable development stage of 2011-2019. National Natural Science Foundation of China was the main fund provider of constructed wetland research. Tongji University, Southeast University and Institute of Hydrobiology, Chinese Academy of sciences were the most published academic institutions. The number of articles published by 10 scholars led by Prof. Wu Zhenbin, accounted for 5.5% of the total number of published papers. Domestic institutions and scholars have close contact and cooperation, and the research hotspots focused on treatments of polluted river and sewage treatment plant tail water, process combination, plant cold tolerance and root system research, emerging matrix development, etc. The future research directions were also proposed including of enrichment of constructed wetland biofilm theory, the engineering application of blocking and overwintering efficient operation technology, the standardization of constructed wetland design and operation management and maintenance.
