Plastic pollution has become a global and persistent challenge, posing threats to ecosystems and organisms. In recent years, there has been a rapid increase in scientific research focused on understanding microplastics in the soil‒plant system. This surge is primarily driven by the direct impact of microplastics on agricultural productivity and their association with human activities. In this study, we conducted a comprehensive bibliometric analysis to provide an overview of the current research on microplastics in soil‒plant systems. We systematically analysed 192 articles and observed a significant rise in research interests since 2017. Notably, China has emerged as a leading contributor in terms of published papers, closely followed by Germany and the Netherlands. Through co-authorship network analysis, we identified 634 different institutions that participated in publishing papers in this field, with the Chinese Academy of Sciences having the most collaborations. In the co-occurrence keyword network, we identified four clusters focusing on the diversity of microplastics within the agroecosystem, transportation, and quantification of microplastics in soil, analysis of plastic contamination type and impact, and investigation of microplastic phytotoxicity. Furthermore, we identified ten research priorities, categorized into the effects of microplastics in "soil" and "plant". The research hotspots were found to be the effect of microplastics on soil physicochemical properties and the synergistic phytotoxicity of microplastics with other pollutants. Overall, this bibliometric analysis holds significant value, serving as an important reference point and offering valuable suggestions for future researchers in this rapidly advancing field.
塑料污染已成为全球性和持久性的挑战，对生态系统和生物构成威胁。近年来，人们对土壤-植物系统中微塑料的研究兴趣迅速增加，这主要是由于微塑料对农业生产力的直接影响以及与人类活动的关联。在本研究中，我们进行了全面的文献计量分析，以提供土壤-植物系统中微塑料研究的概述。我们系统地分析了 192 篇文章，发现自 2017 年以来研究兴趣显著增加。值得注意的是，中国在发表论文方面处于领先地位，其次是德国和荷兰。通过合著网络分析，我们确定了 634 个不同的机构参与了该领域的论文发表，其中中国科学院的合作最多。在共同出现的关键词网络中，我们确定了四个重点关注农业生态系统中微塑料多样性、微塑料在土壤中的迁移和定量、塑料污染类型和影响分析以及微塑料植物毒性研究的集群。此外，我们确定了十个研究重点，分为微塑料在“土壤”和“植物”中的作用。研究热点在于微塑料对土壤物理化学性质的影响以及微塑料与其他污染物的协同植物毒性。总的来说，这项文献计量分析具有重要价值，为该快速发展领域的未来研究人员提供了重要参考点和有价值的建议。
