基于CiteSpace竹子功能性状研究的可视化分析

Visual Analysis of Functional Traits of Bamboo Based on CiteSpace

植物功能性状体现植物与环境的密切关系,能够对不同环境作出相应的影响或响应。以中国知网作为数据来源,利用CiteSpace对竹子功能性状的研究进展、热点和趋势以及主要力量进行可视化分析。结果显示,研究力量以中国林业科学研究院、国际竹藤中心和南方各大林业高校为主,团队内部交流较为密切,但团队之间合作较少,跨地域、机构合作有待加强。关键词中观赏竹、生物量、毛竹林、竹纤维、土壤养分、干旱胁迫等中心性较高,应该重点关注;研究热点主要集中于光合作用、根际土壤养分以及抗逆性。竹子功能性状领域的研究方法已经趋于完善,随着全球气候变化日益严峻,通过竹子功能性状反应所处气候的变化以及群落生态系统功能可能是未来该领域的热点。

Plant functional traits reflect the close relationship between plants and their environment,and can have corresponding effects on or responses to different environments.Using CNKI as a data source,the research progress,hotspots,trends and main research institutions of bamboo functional traits were visualized and analyzed by CiteSpace.The results showed that the main research institutions included the Chinese Academy of Forestry(CAF),the International Centre for Bamboo and Rattan(ICBR)and major forestry colleges and universities in southern China.The internal communication within teams was relatively intense,but the cooperation between teams occurred less frequently,and trans-regional and inter-organizational collaboration had yet to be strengthened.As for the keywords,ornamental bamboo,biomass,Moso bamboo forest,bamboo fiber,soil nutrient,drought stress and so on were highly centralized,which warranted more attention of scientists.The research hotspots were primarily concentrated on photosynthesis,rhizosphere soil nutrients and stress resistance.The research methods in the field of bamboo functional traits are quite sophisticated.As global climate change worsens,it may be promising in the future to reveal the local climate change and the community ecosystem function through bamboo functional traits.
