【目的/意義】從動態視角出發,通過對我國知識圖譜研究的時空及主題演進的可視化分析,梳理其演進特征,提出發展建議,以促進該領域的可持續發展。【方法/過程】以CNKI期刊全文數據庫為信息源,以"知識圖譜"為主題檢索相關文獻。通過函數擬合識別我國知識圖譜發展階段,以k-core方法分析相關機構研究的持續性,以階段新關鍵詞梳理我國知識圖譜在分析方法、分析工具、應用領域及數據來源四方面的演進情況。【結果/結論】我國知識圖譜研究的發展進程可分為起步階段、低速發展階段和高速發展階段,且現如今正處于加速發展期。相關研究機構分布較離散,且研究持續性差。分析方法、分析工具和數據來源較固定,應用領域廣,且其發展呈現出多元化、交叉化、社會化、時代化和國際化的特點。

【Purpose/significance】From the dynamic perspective,through the visual analysis of the space-time and thematic evolution of knowledge mapping research in China, we summarized its evolutional characteristics and proposed development proposals in order to promote the sustainable development of this field.【Method/process】Using CNKI as the data resource, this paper retrieved related literatures about"knowledge mapping". We identified the development stage of knowledge mapping in China through the function fitting, and analyzed the persistence of relevant institutions by the k-core method. With the new keywords in each stage, we untangled the evolution of analysis methods, analysis tools, application fields,and data sources of knowledge mapping research in China.【Result/conclusion】The development process of China’s knowledge mapping research can be divided into starting stage, low-speed development stage and high-speed development stage,and it is now in an accelerated development stage. Relevant research institutes are distributed more discretely and their research is less sustainable. Analysis methods, analysis tools, and data sources are relatively fixed, and the application field is wide and its development is diversification, cross-cutting, socialization, modernization and internationalization.
