Knowledge Map and Topics Analysis on the Research of Lycoris Research based on the Perspective of Literature Metrology

摘要

[Objective]In order to reflect the relationship between literatures quickly and efficiently and reveal the evolutionary path and hotspot,and predict the future trend of Lycoris researches.[Methods]In 19902019,CiteSpace software was used for visual graphic analysis authors,institutes and key words related to Lycoris research based on data sources of WOS and CNKI.[Results](1)Domestic researchers have formed a core group of authors in East China,but the cooperation between the different teams is relatively dispersed.(2)From the perspective of international cooperation level,the cocontribution in China is the largest.Among them,the Chinese Academy of Sciences published has the largest number of papers,and higher research level.(3)The research on Lycoris has experienced three stages:slow accumulation period,rapid growth period and stable growth period.And its research direction develops along the route of“interspecific relationship within genuspropagation and cultivationpharmacology and pharmacodynamicscytology and molecular biologycross breeding”.[Conclusion]The research of Lycoris mainly distributed in Asian countries such as China and Japan.On the whole,its research direction is developing from macro to micro.
