基于CiteSpace的水稻病虫害研究热点与发展趋势分析

Research Hotspots and Development Trend of Rice Disease and Insect Pests Based on CiteSpace

对水稻病虫害的研究回顾是一个繁杂但重要的长期工作,目前已经有部分研究从不同角度对处在不同发展阶段的水稻病虫害知识进行综述回顾,但主要是利用定性分析及传统的文献计量法总结水稻病虫害阶段性技术的发展,难以清晰地呈现海量知识单元间的联系与发展。基于此,采用可视化文献计量分析研究工具CiteSpace,以近30年的中文核心论文为来源,分别对水稻病虫害的文献分布、合作情况、研究热点进行知识图谱构建与数据挖掘分析。结果显示:相关文献数量与质量逐年提升;发文作者间的合作常以“当地植保机构+其他科研机构”的形式出现,但跨地域间作者的合作较少;目前水稻病虫害的研究热点围绕“绿色”和“防治”开展。基于此,对未来水稻病虫害的研究进行了展望,即跨区域交流、绿色防治以及同防治主题相结合的新技术应用将会是未来对水稻病虫害研究的主要方向。

The research review of rice diseases and insect pests is a complicated but important long-term work,at present,some researches have reviewed the knowledge of rice diseases and insect pests in different development stages from different perspectives,however,which mainly use qualitative analysis and traditional literature measurement methods to summarize the development of phased technology of rice pests and diseases,it is difficult to clearly show the connection and development of massive knowledge units.Based on this,CiteSpace,a visual bibliometric analysis research tool,was used to construct knowledge map and data mining analysis on literature distribution,cooperation and research hotspots of rice diseases and insect pests on the basis of Chinese core papers in the past 30 years.The results showed that the quantity and quality of relevant literature increase year by year;the cooperation between authors is often in the form of'local plant protection institutions+scientific research institutions',but there is less cooperation between authors across regions;at present,the research focuses of rice diseases and insect pests are green and control.Based on this,the future research trend on rice diseases and insect pests was forecasted,that is,cross-regional communication,green control,and application of new technologies combined with control will be the main directions of rice disease and insect pest research in the foreseeable future.
