摘要
【目的】通过检索分析根系构型相关研究数据库,以期为进一步研究提供新视野新思路。【方法】基于Web of Science数据库收录2011—2020年有关根系构型研究的相关文献753篇,采用Citespace信息可视化手段对根系构型研究年发文量、研究国家与机构、关键词、研究主旨进行分析,旨在归纳当前研究热点与趋势,总结研究现状,展望未来研究方向。【结果】结果表明,2011—2020年10 a间根系构型文献发表量呈快速上升趋势;主要学科涉及植物科学、农学、土壤科学。中国在该研究发文量占全球总的28.69%;主要关键词为根系生理、根系构型、植物类型等3个聚类,热点关键词为“干旱”和“耐受性”;研究方向可分为探测技术、环境影响、根系生长特性、自身调控等4个聚类,其中环境影响为热点研究方向。研究方向自探测技术和根系生长特性(2011—2013年)、植株自身调控及根系生长特性(2014—2017年)至环境影响(2018—2020年)逐步过渡。【结论】鉴于目前研究多集中于根系本身或根系周围环境对土壤微生物、土壤水分生态及土壤养分生态的影响,推断地上部响应根系构型变化以适应全球气候变化可能会成为未来研究热点。
【Objective】This study was conducted to provide new vision and new ideas for further research through analyzing the related research data of plant root system architecture.【Method】Synthesis research was conducted to illustrate the research outline of root system architecture based on 753 pieces of literatures in the database of Web of Science from 2011 to 2020 with the subject of“root system architecture”.Citespace information visualization method was used to analyze the annual number of literatures,countries and institutions,keywords,and research themes in the field of root system architecture,aim to summarize current research hotspots and trends,summarize the current research status,and prospects for future research directions.【Result】The result showed that the number of literature publications was continually increased from 2011 to 2020.The main subject categories were plant science,agronomy,and soil science.China contributed 28.69%of the total global research output in this field.The main keywords were divided into three clusters:root physiology,root system architecture,and plant type,with“drought”and“tolerance”being the hot keywords.The research interests were classified into four clusters:detection technology,effects of environment factors,root growth characte-ristics,and self-regulation.Among these,effects of environment factors emerged as a hotspot research direction.The research direction gradually transitioned from detection technology and root growth cha-racteristics(2011 to 2013),plant self-regulation and root growth characteristics(2014 to 2017),to environmental impact(2018 to 2020).【Conclusion】Given that current research mostly focuses on the effects of root architecture on soil microbiota,soil water and nutrient ecology around the root system,it is inferred that the aboveground response to changes in root architecture to adapt to global climate change may become a future research hotspot.
