摘 要:以CSSCI中2000—2011年299篇生态安全研究论文为研究对象,采用文献共被引网络、关键词共现网络及突现词分析,以信息可视化为手段,对国内生态安全研究现状进行了分析。研究发现,目前国内生态安全研究已完成了基础理论和研究体系的架构,但研究网络过于集中,前沿分支较少。生态安全研究起源、生态安全基础理论、生态风险评价、生态系统评价、土地生态安全研究是国内生态安全研究的主要知识群组。国内生态安全研究主题集聚成3条核心路径:"生态安全基础理论研究"路径、"生态安全-生态系统评价-区域生态安全评价-生态预警"路径、"生态安全-生态风险评价-农村资源生态系统-土地生态安全研究-生态预警"路径。生态预警及土地生态安全研究成为当前生态安全的研究前沿,生态安全研究更趋向于对特色性的生态系统进行分析与评价。Research into ecological security has aroused the widespread attention of scholars. The many differences in ecosystem type,number,spatial distribution and ecological evolutionary process has caused domestic scholars to be continuously innovating. In recent years,alongside enhancements to the basic theory and improvement in research systems,ecological security research has formed different research centers and broken new frontiers. This paper synthesizes information visualization methods,bibliometric methods and data mining algorithms and visualizes the development process and structural relationship of ecological security research using the information visualization analysis software,Citespace II.The research uses data from 299 articles about"ecological security"in the CSSCI database during 2000—2011. Using the co-citation network analysis and burst detection,we analyze the domestic research status of the ecological security research field. The results reveal that domestic research falls into categories of basis theories and system construction: the study of the origin of ecological security, ecological security basic theory, ecological risk assessment, ecological system assessment, and land ecological security,which form the main knowledge groups of domestic ecological security research. The ecological security co-citation network provides visual displays of the evolution path among the knowledge groups of ecological security research. This indicates that ecological security research formed the evolution of knowledge and theory,reflecting the coherence and extension of ecological security research. In short,"the study of the origin of ecological security"is at theedge of the network,showing some independence and is less associated with the follow-up study. "Ecological security basic theory"is in the network center and shows the basis theories of ecological security research. This shows a close correlation with the surrounding, "ecological risk assessment " and "ecological system assessment
