Abstract:

To address the issue of intensifying soil acidification threatening agricultural production, this study systematically reviews the current status and trends of research on soil acidification regulation in China. Based on 386 Chinese core journal articles from the CNKI database (2004-2024) focusing on soil acidification regulation strategies, bibliometric analysis was conducted using CiteSpace 6.4R1 software from the perspectives of annual publication volume, research institutions, author collaboration, and keyword clustering. The results show that: (1) the development of this research field can be divided into three stages: slow growth from 2004 to 2015, stable fluctuation from 2016 to 2021, and rapid growth from 2022 to 2024. (2) Collaboration among institutions and authors presents a pattern of “local concentration but overall dispersion,” with Huazhong Agricultural University (18 articles) and Fujian Agriculture and Forestry University (9 articles) as core research institutions. Author collaboration is mainly characterized by small-scale clusters, reflecting relatively weak overall coordination. (3) Keyword clustering formed 14 core themes, including “lime amendment,” “biochar application”, “straw return”, and “microbial regulation”. In recent years, “biochar”, “microbial inoculants”, and “calcium-magnesium fertilizers” have emerged as research hotspots. Research on soil acidification regulation in China has shifted from a single chemical amendment approach to an integrated chemical-organic-biological regulation paradigm. Current studies focus on technological pathways and crop planting patterns adapted to different acidified soil characteristics, providing important bibliometric references and technical support for the precise management of soil acidification, cultivated land quality protection, and sustainable agricultural development in China.
