文章先采用内容分析法对国内知识图谱研究论文中的软件引用情况进行深入细致分析，再利用扩散广度和扩散速度等知识扩散指标对论文中发现的高频使用的10个知识图谱软件在学术交流系统中的扩散特征进行探索性研究。结果表明：国内知识图谱研究对软件的依赖程度不断提升，2017年提及软件的论文占比超过90%，然而这并未带来软件引用缺失状况的改善，软件引用缺失依然严重；知识图谱研究人员接受和使用新软件的速度在不断加快；知识图谱软件起初的扩散比较缓慢，随着时间的推移而不断加快，目前仍未见扩散放缓；知识图谱软件较早地出现在图书馆、情报与文献学、管理学、新闻学与传播学和计算机科学领域，并在图书馆、情报与文献学、教育学和管理学研究中获得最广泛的应用。

The paper first examines the citation of software in Chinese core journal papers on knowledge mapping using a content analysis approach, and then explores the diffusion characteristics of the top ten most frequently used knowledge mapping software tools with several diffusion indicators such as diffusion breadth and diffusion speed. The findings are as follows:（1）Knowledge mapping research increasingly relies on software and the proportion of papers about knowledge mapping using software is more than 90% up to 2017. However, the state of software citation practice does not become better and the uncitedness of software in domestic knowledge mapping research is still noticeable.（2）The speed of new software acceptance and usage of Chinese researchers in the field of knowledge mapping is increasing.（3）The knowledge mapping software tools have been adopted slowly in early years, but afterward the diffusion speed grows rapidly up to now.（4）The knowledge mapping software tools have occurred earlier in the fields of library, information and document science, management, journalism and communication, and computer science. And they have been more frequently used in the research of library, information and document science, education and management.
