Abstract [Objective]To help Nangao pear researchers to understand the current research direction and focus in the Nanguo pear.[Method] Chinese core journals about Nanguo pear of CNKI database in 1990-2019 were selected as the data sample,as well as degree papers of master and doctor and SCI(Science Citation Index).Based on bibliometrics,with knowledge mapping as the research vector,Excel,CiteSpace and other analysis software were used as the tools.Clustering analysis of subject words and key words of the selected data was carried out.And at the same time,data analysis and mapping of Nanguo pear was established.[Result]The research on Nanguo pear started in 1992 and reached its peak in 2009.The key words of Nanguo pear research were mostly 1-MCP (1-methylcyclopropylene),aroma and refrigeration.The core authors in the research field of Nanguo pear in China included Ji Shujuan,Li Juncai,Wang Jiazhen,Xin Guang,Cai Zhongmin,Liu Yanji.Among the research institutions,Shenyang Agricultural University had the largest number of published papers,cooperative relations and master and doctoral dissertations in journal papers.[Conclusion]In recent years,the research hotspots and trends of key words might be Nanguo pear,salicylic acid,1-methylcyclopropene,gene expression,refrigeration and so on.

南果梨是秋子梨系统梨属蔷薇科中最优良的品种之一,原产辽宁鞍山,已有150多年的栽培历史[1],是辽宁省鞍山等地的特产水果[2]。南果梨的果实品质、丰产措施以及产品加工等研究一直是科研学者关注的重点,科研试验屡见不鲜,因而对南果梨进行文献计量学统计分析有一定必要性。文献计量学就是以文献体系和计量特征为研究的对象,运用数学、统计学等计量方法,研究文献的分布、数量、变化和管理,进一步探讨科学技术的某些结构、特征和规律的一门学科[3]。……
