摘　　要：在稻田湿地生态系统中,土壤对磷的吸附和释放特征在作物生长以及环境保护中发挥着重要作用,利用CiteSpace软件对1992—2022年中国知网(CNKI)数据库中有关磷的吸附和释放方面的研究文献进行可视化和计量分析,总结了稻田湿地磷的输入与输出概况、梳理磷的吸附和释放研究的发展脉络、利用普赖斯理论计算核心作者群体以及追溯探讨磷的吸附和释放在稻田湿地中的主要研究热点与应用情况。结果显示,1992—2022年有关磷的吸附和释放研究有1130篇文献,发文量整体趋势呈波浪式上升状态,大量学者对该领域愈发关注。对核心研究人员进行分析发现,以上海海洋大学林伟健、詹艳慧等为中心的研究团队发文量居于榜首,但不同作者之间合作较少。对关键词进行聚类分析后可将磷的吸附和释放研究内容分为4类,主要涉及在磷形态分布、磷的吸附和释放的影响因素、土壤吸附和释放磷能力的评估以及利用数学模型探讨磷的吸附和释放过程4个方面。稻田湿地中磷的迁移转化与磷流失的环境风险问题成为该领域的研究热点,覆盖技术和生物炭的使用是今后的研究趋势,将成为大量学者重点研究方向。有关磷的吸附释放研究愈发受到重视,发文量以及研究方向不断上升和扩散,在稻田湿地中的应用研究还不够广泛,各研究机构和学者之间要不断加强进一步的合作探讨,利用新技术促进稻田湿地的农业资源利用和推动生态环境的可持续发展。In paddy wetland ecosystems,soil phosphorus adsorption and release characteristics play an important role in crop growth and environmental protection.CiteSpace software was used to visualize and econometrically analyze the research literature on phosphorus adsorption and release in CNKI database from 1992 to 2022,summarized the input and output of phosphorus in paddy wetlands,sorted out the development context of phosphorus adsorption and release research,used price theory to calculate the core author group,and retrospectively explored the main research hotspots and applications of phosphorus adsorption and release in paddy wetlands.The results showed that there were 1130 articles on phosphorus adsorption and release from 1992 to 2022,and the overall trend of publication volume was rising in waves,and a large number of scholars were paying more and more attention to this field.An analysis of core researchers found that the research team centered on Lin Weijian and Zhan Yanhui of Shanghai Ocean University ranked first in the number of articles,but there was little cooperation between different authors.After cluster analysis of keywords,the research content of phosphorus adsorption and release could be divided into four categories,mainly involving four aspects of phosphorus morphological distribution,influencing factors of phosphorus adsorption and release,evaluation of soil adsorption and phosphorus release capacity,and the use of mathematical models to explore the adsorption and release process of phosphorus.The migration and transformation of phosphorus in paddy wetlands and the environmental risk of phosphorus loss had become research hotspots in this field,and the use of covering technology and biochar were future research trends and would become the key research direction of a large number of scholars.In general,the research on the adsorption and release of phosphorus had received more and more attention,the number of papers and research directions continued to rise and spread,and the application research in
