印度梨形孢文献计量学研究态势分析

为进一步了解和明确印度梨形孢(Piriformospora indica)的全球现状和研究热点,基于Web of Science平台科学引文索引扩展板(Science Citation Expanded,SCIE)数据库,对2008—2018年印度梨形孢领域的SCI文献进行计量学分析,探讨此领域的研究重点以及未来的发展趋势。结果显示：2008—2018年印度梨形孢研究论文数量共392篇;文献产出量总体呈上升趋势,2017年文献数量最高;德国、印度、美国、中国、伊朗文献数量居世界前5位,其中德国文献数量最多,为118篇;吉森大学和耶拿大学的发文量居世界研究机构前两位;最有学术影响力的核心作者来自印度;主要核心期刊是《SYMBIOSIS》、《MOLECULAR PLANT MICROBE INTERACTIONS》、《NEW PHYTOLOGIST》;主要学科是植物科学、微生物、生物技术。综合来看,德国和印度在印度梨形孢研究领域处于优势地位,中国在印度梨形孢的研究还处于初级阶段,有待更多学者关注这一领域。

Bibliometric study of Piriformospora indica

To further clarify the global status and research hotspots of Piriformospora indica, based on the Science Citation Expanded (SCIE) database of Web of Science platform, the bibliometric analysis of SCI literature in P. indica field from 2008 to 2018 is carried out, and the research focus and future development trend in this field are discussed.
