Abstract:

Water pollution and eutrophication have become a prominent problem in global water environment governance. Plant purification of water quality has become the core technology of ecological restoration due to its green, economic and sustainable characteristics. However, there was a lack of panoramic knowledge map and frontier trend combing in the field for a long time. To clarify the development context, research core, and trends in the field of plant purification of water quality, a bibliometric analysis was conducted based on 1904 relevant literatures on plant water purification, which retrieved from 1995 to 2024 from the Web of Science database using CiteSpace Software. The research status, core themes, distribution of research forces, and frontier trends were systematically reviewed in this domain. The results showed a phased growth in annual publications from 1995 to 2024, with a rapid expansion commencing after 2016. This trend reflected that this field had become a research hotspot driven by the demand for ecological environment management. China had made the most prominent contribution to research on plant purification of water quality with 491 publications, among which the Chinese Academy of Sciences served as the core institution. Countries such as the United Kingdom and France also played important roles in international cooperation. Keyword co-occurrence and cluster analysis indicated that the research focused on water purification and pollutant removal, covering topics such as constructed wetlands, nitrogen and phosphorus removal, and ecosystem services, forming a multi-level correlation system. Research frontiers had shifted from basic technical studies toward refined governance and comprehensive consideration of ecological benefits. This study can provides references for the development and application of plant purification of water technologies, contributing to water pollution control and ecological restoration practices.
