摘要
近年来,国际上关于生态安全研究的文献大量涌现。随着全球变化和人类活动影响加剧,生态安全研究正发生着深刻变化,呈现出多目标、多层次、多学科交叉综合的复杂特点,研究主题日益丰富,但模糊性和争议性问题一直存在,对已有文献成果进行系统分析非常有必要。利用引文网络分析可视化工具CitespaceⅡ,通过绘制科学知识图谱,以定量与定性相结合的可视化文献综述研究方法,对各国学者发表的生态安全研究成果进行系统分析梳理,展示了研究主题的演进轨迹和发展趋势,总结了其发展变化的内在原因。研究表明:生态安全的研究主题可分为持续性和阶段性两类,主题演化轨迹符合Gartner光环曲线理论,人类文明发展阶段、国际政治经济格局、学科研究水平是决定生态安全研究阶段和主题演变的主要因素,该领域经历了问题提出与概念形成期、奠基拓展期、纵深发展期3个阶段,各阶段都有一些关键文献出现,这些引领学科发展的经典文献以自然科学研究为主;全球化、生物多样性、生态农业与农业集约化、恢复力、脆弱性是当前生态安全领域的研究热点;保障人类生存发展基本需要和人对环境变化的适应与响应将是21世纪生态安全研究的主要方向。
In recent years, there has been a surge in international research literature on ecological security. With intensifying global change and human actions, this research field has been profoundly transformed. While research on ecological security is muhitargeted, multilevel, and muhidisciplinary, revealing integrated and complex characteristics, fuzzy and controversial issues have persisted. The use of traditional and current methods for researching publications is limited when applied to large quantities of literature, because they are qualitative, non-visual, and manual. This paper focuses the application of Citespace 11 , which is a visualization tool for conducting both quantitative and qualitative citation network analysis of visual literature reviews. We used this tool to analyze classical literature and literature with a research focus on this field, documenting the association of a co-citation network with a keyword co-appearance network. We applied three methods available in Citespace II to examine the evolutionary trajectory of research topics and their development trends. These methods included keyword frequency analysis, document clustering analysis, and the burst detection algorithm. The use of these methods enabled us to identify causative factors in the development of research topics. We conducted scientific knowledge mapping to analyze and locate research and scholarship studies on ecological security globally. These are three factors： （1） different stages of human civilization, （2）patterns of international politics and the global economy, and （3） the level of research on subjects that are formative at different stages of ecological security research and the evolution of research themes. Our results showed that this research field has undergone three procedural phases from the initial stage of asking questions and forming concepts, to the research development stage, and finally in- depth research. Seminal literature has emerged during these different stages of research. Our study reveale
