Abstract:

The paper aims to understand the latest research progress, hot spots and development trends in the field of constructed wetlands at home and abroad, and to provide data basis and reference for relevant researchers. The literature related to constructed wetlands from 2000 to 2019 in the core database of Web of Science was used as the data source, we conducted a bibliometrics analysis with the package ‘bibliometrix’ in R. The results showed that the number of literature related to constructed wetlands generally increased during 2000 to 2019. The journal Ecological Engineering had the most publications in this study field. The most frequently cited article was published by Vymazal in Science of the Total Environment in 2007. China, USA and Spain were the top three countries in the world for the number of publications, and the Helmholtz Center for Environmental Research in Germany was the most prolific research institute. The removal of pollutants such as nitrogen and phosphorus and the performance of constructed wetlands have always been the hotspots of research in this field. The field of constructed wetland research is still in a rapid development stage.

Key words: constructed wetland, bibliometrics, R language, research progress, research hotspot
