基于文献计量分析中国全生物降解地膜研究发展态势

为深入了解全生物降解地膜研究的发展现状、研究热点和趋势，整理并筛选了1990—2022-08CNKI数据库、万方数据库和Web of Science核心合集收录的全生物降解地膜的论文，采用文献计量学方法，结合Citespace对该领域发文量、主要发文机构和试验省份、试验作物和高引文献等进行了可视化分析。结果表明:该领域发文量呈上升趋势，2011年后发文量迅速增长；从发文机构来看，西北农林科技大学、中国农业科学院和石河子大学为主要的研究机构，在该领域发文量最高；主要试验省份集中在西北地区，涉及试验作物包括马铃薯、棉花和花生等；研究趋势主要集中在全生物降解地膜本身降解性能和对作物产量、土壤水分、水分利用率影响及其应用效果等方面。鉴于全生物降解地膜在不同地区的使用效果不同，不同配方的全生物降解地膜对作物产量影响不同，未来研究热点应是全生物降解地膜替代普通地膜进行农田应用以及不同颜色、厚度和成分的全生物降解地膜对增温保墒除草的影响。

Development situation analysis of biodegradable mulch film based on bibliometric analysis in China

In order to gain an in-depth understanding of the development status, research hotspots and development trends of biodegradable mulch film research, this research systematically sorted and screened the papers of the total biodegradable mulch film included in the CNKI database, Wan Fang database and Web of Science from 1990 to August 2022. Combining bibliometric analysis with Citespace method, this study visually analyzed the number of articles published in the field, main publishing institutions and test provinces, experimental crops and the highly cited literature. The results showed that: The number of articles published in this field displayed an upward trend, and the number of articles published in this field increased rapidly after 2011. From the perspective of major publishing institutions, Northwest A & F University, Chinese Academy of Agricultural Science and Shihezi University were the major research institutions with the highest amount of publication in this field; The main experimental provinces were concentrated in the northwest region, and the main crops were potato, cotton and peanuts. In conclusion, the application process of the biodegradable mulch film in the application process of the farmland is roughly the same as the ordinary mulch film in heat, preservation and crop yield improvement. The degradation of biodegradable mulch film is greatly affected by natural conditions, soil environment and its own composition, the future research on biodegradable mulch film in China needs to be strengthened.
