Abstract
Based on the VOSviewer software and bibliometric visualization analysis, with 4636 published papers from 2000 to 2021 included in the Web of Science (WOS) Core Collection and China National Knowledge Infrastructure (CNKI) database, this study reviewed the literature on the effects of droughts and floods on phosphorus through three aspects: publication date, keywords, distribution of research discipline, etc. The results show that the research has risen rapidly in recent 20 years, and the average annual literatures in the WOS database increased 18.44 times faster than that in the CNKI database. The main keywords contain growth, responses, plants, tolerance, climate change, eutrophication, soil fertility, management, etc. The research in this field has the characteristics of interdisciplinary development. The paper aims to systematically review the effects of droughts and floods on phosphorus in soil-plant ecosystems, which could guide study trends in the future, such as quantitative evaluation, impact mechanism and adaptation countermeasures.
