基于CiteSpace的桉树混交林发展现状分析

Analysis of Development Status of Eucalypt Mixed Plantations Based on CiteSpace

为了解桉树混交林研究现状和发展趋势,以CNKI数据库为文献来源,采用文献计量法对1978—2022年桉树混交林相关文献进行分析。结果表明:桉树混交林领域研究可分为缓慢起步、平稳增长和急剧上升3个阶段;前沿主题包括土壤养分、林分生长;研究趋势主要集中在桉树树种、伴生树种、生物量、混交造林等;农林类高校及科研院所、林场、林业局等单位是文献产出的主要机构,总体表现为省(自治区)内部合作较多、跨省(自治区)之间合作较少;作者主要来自科研机构或者高校,不同机构间交流和合作较少。

In order to understand the research status and development trend of mixed species plantations involving eucalypts,the CNKI database was used as the literature source,and the related literature from 1978 to 2022 was analyzed by bibliometric methods.The results showed that research on eucalypts in mixed species plantations could be divided into three stages,namely slow start,steady growth and sharp rise.Frontier topics include soil nutrients and stand growth.The research trends mainly focus on eucalypt species,associated tree species,biomass,mixed afforestation and so on.Agricultural and forestry universities,research institutes,forest farms,forestry bureaus are the main institutions involved in producing the published reports.The overall performance is that there is more cooperation within provinces(autonomous regions)and less cooperation between provinces(autonomous regions).The authors are mainly from scientific research institutions or universities,and it seems communication and cooperation between different institutions is relatively low.
