Abstract: Based on database provided by Web of Science, literature of the research results of wastewater treatment that had been used by constructed wetlands in recent 16 years were analyzed both in China and abroad in order to understand the development of wastewater treatment in constructed wetlands. The results showed that the publication quantity of international research findings was fluctuated with years from 2001 to 2016, and in general they were in an uptrend. The top five countries in terms of publication quantities were China, USA, Spain, Canada and Germany, among which China contributed the most, accounting for 21.1% and showing a great growth in publication quantities after 2007. Compared to western countries, China was low in citing rates of literature and in short of articles with high impact factors, which indicated the level and depth of China research remained to be further improved. This paper briefly analyzed the present research situation of wastewater treatment that had been used by constructed wetlands in China, and looked into the future development with positive anticipation.
