基于文献专利计量的重大植物疫情领域态势分析

对2011—2020年国内外重大植物疫情领域期刊论文和专利进行分析，深入了解植物疫情研究现状及前沿动态，以期为国内该领域创新发展、植物疫情防控体系构建提供有价值的参考。采用文献计量学方法对2011—2020年Web of Science核心数据集中国内外重大植物疫情领域国家、期刊、被引频次等进行梳理，由关键词分析得到研究前沿及热点，采用专利计量对地区分布及技术领域等进行分析。全球重大植物领域科技创新稳定发展，发文量和专利数持续上升。中国论文发表总量和专利数位居世界第一，但国际合作程度和论文篇均被引频次较低，国内高发文量作者数目较多但作者间国际合作程度较低。该领域研究热点主要集中在疫病识别及其防治，病虫害化学生态学如抗药性监测、农药风险评价，以及生物功能基因层面研究等方面。中国虽在该领域研发实力较强，但需加强国内外优势领域交流学习提高自身影响力，积极开展国际技术研究合作，为长期有效控制植物疫情发展提供有力支撑。

Current Status of Research on Major Plant Epidemic Based on Bibliometrics and Patentometrics

This study analyzed journal papers and patents in the field of major plant epidemic at home and abroad from 2011 to 2020, explored current situation and cutting-edge trends of plant epidemic research, aiming to provide valuable reference for the research innovation in this field and the construction of plant epidemic prevention and control system in China. The bibliometric method was used to sort out the paper publishing countries, journals and cited frequencies in the field of major plant epidemics at home and abroad from 2011 to 2020 in Web of Science core collection, and the research frontiers and hotspots were obtained by keyword analysis. The regional distribution and technical fields were analyzed by patentometrics. Scientific and technological innovation in major plant fields in the world developed steadily, and the number of published papers and patents continued to rise. China ranked first in the total number of published papers and patents in the world, but the degree of international cooperation and the citation frequency of papers were low. China had a large number of authors with high publication volume, but the degree of international cooperation among authors was low. Research hotspots in this field mainly focused on disease identification and control, and chemical ecology of diseases and pests, such as drug resistance monitoring, pesticide risk assessment, and research on biological functional genes. Although China has strong research and development strength in this field, it still needs to improve exchanging and learning ability in domestic and foreign advantageous fields to enhance its influence, and actively carries out international technical research cooperation, so as to provide strong support for the development of long-term effective control of plant epidemic.
