矿物肥施用对土壤生态效应的影响研究热点及趋势的文献计量分析

为全面了解矿物肥对土壤生态效应影响的研究现状，该文检索了Web of Science核心数据库1995—2021年关于矿物肥施用对土壤生态效应影响的研究论文，并利用文献可视化软件VOSviewer和CiteSpace对检索到的相关文献的年发文数量、文献被引频次、核心作者与国家(地区)、学科分布及关键词进行分析，追溯探讨了矿物肥对土壤生态效应影响研究的发展概况及热点方向.研究结果表明：1995—2021年间矿物肥对土壤生态效应影响研究的发文数量不断增加；中国总发文量位居世界第1,但相关研究创新性仍需进一步提高；核心作者组内联系较紧密，中国科学院是发文数量最多的研究机构.矿物肥对土壤生态效应影响的研究涉及环境科学、林学和农学等多个学科，研究热点集中在土壤养分循环、重金属污染土壤修复、土壤微生物群落结构变化等方向.未来应加强矿物肥对土壤碳循环、土壤生态系统稳定性的影响等方向的研究.

The Bibliometric Analysis of Research Hotspots and Trends in the Effects of Mineral Fertilizer Application on Soil Ecological Effects

In order to comprehensively understand the research status of the impact of mineral fertilizer on soil ecological effects,the research papers on the impact of mineral fertilizer application on soil ecological effects from 1995 to 2021 in the Web of Science core database are searched,and the literature visualization software VOSviewer and CiteSpace are used to analyze the annual number of publications,citation frequency,core authors and countries,subject distribution and keywords of the retrieved relevant literature.The development overview and hot directions of the research on the impact of mineral fertilizer on soil ecological effect were discussed retrospectively.The results show that the number of publications on the influence of mineral fertilizers on soil ecological effects has been increasing during 1995—2021.China accounts for the largest number of publications in the world,but the innovation of related research still needs to be further improved; the core authors are closely connected within the group,and the Chinese Academy of Sciences is the research institution with the largest number of publications.The impact of mineral ferti-lizers on soil ecological effects involves many disciplines such as environmental science,forestry and agronomy,and research hotspots focus on soil nutrient cycling,remediation of heavy metal contaminated soil,and changes in soil microbial community structure.In the future,the research on the impact of mineral fertilizer on soil carbon cycle and soil ecosystem stability shall be strengthened.
