| 为深入了解塑料地膜研究的发展现状，本研究以 2000—2019年 Web of Science 数据库收录的1 895篇论文为数据来源，采用文献计量学方法，结合运用Excel、VOSviewer等软件对该领域发文量、主要发文国家和机构、研究主题、研究前沿等进行了统计分析。结果表明:该领域发文量呈上升趋势，2013年后发文量迅速增长；从国家研究实力上来看，中国、美国、意大利为发文量较高的国家；以西北农林科技大学、中国科学院、中国农业大学为主的中国研究机构在该领域发文量最高；该领域的研究方向主要包括:塑料地膜在农业上的应用(包括覆膜对农产品产量、土壤水分、温度的影响等)，地膜的高分子材料分析、生物可降解地膜的研发与应用，地膜的生物降解，塑料残膜对土壤环境、生态环境的影响等方面；从研究趋势上看，鉴于农业残膜在土壤中的大量残留，未来研究热点可能会趋于塑料残膜对生态环境、土壤质量的影响，尤其是塑料残膜中增塑剂及降解后的微塑料对土壤食物链安全、生态系统和人体健康的风险值得进一步探究。研发新型生物地膜替代传统塑料地膜，并及时评估其农业应用效果、尽早大范围推广至关重要。 |

| Abstract: |
| In order to have an overall understanding of the research in plastic mulching film, this study takes the data of 1 895 papers collected from the Web of Science database from 2000 to 2019 as the data source, based on the method of bibliometrics, combined with the software such as Excel and VOSviewer, the number of published papers in plastic mulching film research, major countries and institutions where issued the publications, research topics and research frontiers were analysis. The results showed that: there was an increasing trend on the number of published papers in this field. Since 2013, the number of publications has been increasing rapidly. From the perspective of national research abilities, China, the United States and Italy contributed most of publications, Chinese research institutions contributed the highest number of papers in this field, as Northwest A&F University, Chinese Academy of Sciences and China Agricultural University; The research directions in this field include the application of plastic mulching film in agriculture(including the influence of film on agricultural output, soil moisture, temperature, etc. ), polymer material analysis of mulching film, development and application of biodegradable mulching film, biodegradation of mulching film and influences of plastic residual film on soil environment and ecological environment. From the perspective of research trends, as large residual of mulching film remains in soil, the future hotspots of the frontier may be biased towards the impacts of plastic film residual on the ecological environment and soil quality. Especially the effects of plasticizer and microplastics on soil food chain safety, ecosystems, and human health deserve further investigation. At the same time, it is important to develop biodegradable mulch films to replace traditional plastic mulch films, evaluate the effects of agricultural applications in time, and promote the biodegradable mulch films on a large scale as soon as possible. |
