摘要

Recent research on phosphorus in saline-alkali soils has garnered significant attention, leading to numerous publications. This study systematically explores the historical development, current status, and future trends of the field. Data were sourced from the Web of Science and analyzed by the software CiteSpace and VOSviewer. Through in-depth scientometric analysis of 550 publications, the most influential journals, countries, institutions, authors, and publications were identified, and collaboration networks, co-citation networks, and keyword networks were constructed. The journal with the highest publication output is Agronomy Basel. China leads in paper output, while France excels in research collaboration networks. The Chinese Academy of Sciences leads among institutions in publication count. Literature co-citation and clustering analysis reveal the mainstream research content and directions, encompassing biochar addition, soil aggregates, soil remediation, composting technology, stress factors, enzyme activity, and microbial diversity. Keyword clustering and burst detection highlight current hotspots: improving plant salt tolerance, organic carbon-driven ecological restoration, and water dynamic regulation. Research hotspot visualization further reveals four potential future hot directions: multi-factor synergistic regulation of phosphorus availability, microbe-mediated phosphorus cycle mechanisms, precision agriculture technology, and ecological restoration and carbon sequestration. Several suggestions for future research are proposed. This study effectively eliminates subjective judgment biases and provides readers with a clear presentation of the latest advancements and development trends in saline-alkaline soil phosphorus research.
