基于Citespace知识图谱分析国际城市生物多样性研究

Knowledge mapping analysis of urban biodiversity research based on Citespace

生物多样性保护一直是城市生态学与风景园林学的重要议题。以Web of Science核心数据库收录的近二十几年(1999—2020)的城市生物多样性文献为研究对象,利用文献计量分析与可视化知识图谱分析方法,将检索并剔除重复后的770篇文献导入Citespace5.7.R2中。进一步分析了其时间与期刊分布,学科与研究方向分布,及国家与机构合作分布等基本特征;进行了外文文献中城市生物多样性的文献共被引分析与共现知识图谱分析;并利用关键词共现分析了其研究热点;突现词突发性探测算法分析了其研究前沿,包括四大方向:城市化对生物同质与物种丰富度的影响;城市绿地管理与生物多样性保护;城市生物多样性保护的关键因素;提高公众的保护意识与参与性。以期为相关科研工作者与我国城市生物多样性相关研究提供参考与借鉴。

Biodiversity conservation has always been an important topic in urban ecology and landscape architecture. In this paper, the urban biodiversity literature, from 1999 to 2020, were collected in the core database of Web of Science. 770publications were retrieved and analyzed after eliminating the duplicates by using the bibliometric analysis and visual knowledge map analysis in CiteSpace 5.7.R2. Further analysis of its basic characteristics was done, such as the distribution by year and journals, the development of disciplines and research areas, and countries and institutions distribution. Besides,the co-citation analysis and co-occurrence knowledge map analysis of urban biodiversity in the English literature was carried out. Keywords co-occurrence analysis reveals the research hot spots. The burst detection algorithm tells the research frontiers,including four areas: the impact of urbanization on biological homogeneity and species richness;urban green space management and biodiversity conservation;key factors for urban biodiversity conservation;the enhancement of public awareness and participation in biodiversity protection. This paper aims to provide a reference for related researchers and research on urban biodiversity in China.
