This review provides a comprehensive analysis of the application of the Braun-Blanquet approach in ecological research, based on 1168 studies identified through a systematic review using PRISMA guidelines and VOSviewer software. The number of publications on the Braun-Blanquet approach has been growing exponentially, indicating increasing scientific interest and ongoing development. Key research areas include improving the conceptual and methodological foundations of the approach, enhancing regional vegetation classifications, expanding geographical coverage, updating phytosociological databases, and addressing the continuity and discreteness of vegetation in ecological classifications. The top 20 most cited journals and authors are identified, revealing a concentration of high-impact research in Eurasia. The analysis of the bibliometric network shows changing relationships over time, with most researchers publishing only one to three papers. The Braun-Blanquet approach is integrated into forest typologies, enhancing their ecological validity and environmental relevance. The approach is effective for identifying climatic influences on vegetation distribution and is used in various classifications, including the Biogeoclimatic Ecosystem Classification in Canada and the Russian genetic typology. The approach is also applied in vegetation mapping, which is crucial for biodiversity conservation and sustainable land use. Despite its strengths, challenges remain, including the need for more comprehensive data analysis and the integration of remote sensing technologies. The Braun-Blanquet approach is particularly valuable for studying dynamic vegetation and its response to environmental changes. The review highlights the importance of the approach in ecological classification and its potential for further development in addressing global environmental challenges. The study emphasizes the need for continued research to refine and expand the application of the Braun-Blanquet approach in environmental science.This review provides a comprehensive analysis of the application of the Braun-Blanquet approach in ecological research, based on 1168 studies identified through a systematic review using PRISMA guidelines and VOSviewer software.
