微塑料（粒径<5 mm）作为新型环境污染物污染土壤生态环境。为全面了解微塑料在土壤环境中的研究现状和发展趋势，采用VOSviewer和Cite space可视化分析软件分析工具，对Web of Science核心合集数据库中2012~2023的土壤环境领域的文献进行可视化统计分析。结果表明：自2017年以来，与土壤微塑料领域相关的研究迅速增长；中国在土壤微塑料领域进行了大量的研究，发文量明显高于其它国家；土壤微塑料研究领域发文量最多的期刊为Science of the total environment（92篇），为平均每篇被引量最高的期刊；通过关键词分析，土壤微塑料领域的研究内容包括对土壤环境中微塑料的提取与检测、微塑料的降解以及微塑料与其他物质（重金属、有机污染物等）的复合污染，此外还包括微塑料在土壤中的迁移和对植物、微生物的影响以及对生态环境的影响。目前热点逐渐从大尺寸的微塑料单一污染物对环境的影响等变化为对土壤环境中赋存的小尺寸纳米塑料展开研究，以及微塑料与其他污染物（重金属等）的复合污染等更深层次的研究中。为土壤微塑料后续的研究方向提供科学依据，并为其在环境领域的应用提供有力的参考。
Microplastics (particle size less than 5 mm) as a new type of environmental pollutant, and the soil ecology were polluted. In order to comprehensively understand the research status and development trend of microplastics in soil environment, VOS viewer and Cite space were used to visual analysis software analysis tools. The literature in the field of soil environment from 2012 to 2023 in the core collection database of Web of Science was visually analyzed. Results indicate that for the research related to the field of soil microplastics had grown rapidly since 2017. China had carried out a lot of research in the field of soil microplastics, and the number of publications was significantly higher than that of other countries. The journal with the largest number of publications in the field of soil microplastics research was Science of the Total Environment (92 papers), and it was also the journal with the highest number of citations per article. The research in the field of soil microplastics included the extraction and detection of microplastics in the soil environment, the degradation of microplastics, and the compound pollution of microplastics and other substances (heavy metals, organic pollutants, etc.)were analyzed. It also included the migration of microplastics in the soil and the effects on plants, microorganisms, and the ecological environment. At present, the focus had gradually changed from the process changes such as the impact of a single pollutant of large-sized microplastics on the environment to the small-sized nanoplastics occurred in the soil environment, as well as the composite pollution of microplastics and other pollutants (heavy metals, etc.) and other deeper research. It was provided that a scientific basis for the follow-up research direction of soil microplastics, and a strong reference for its application in the environmental field.
