〔摘 要〕本文采用学科交叉指数及科学叠加图可视化技术对我国CSSCI数据库中4种情报学的核心期刊2006-2015年刊载的13 098篇文献进行分析，用以揭示我国情报学学科交叉性的特征及变化。结果表明，被引学科的频率分布符合幂律分布，10年间我国情报学与国内外人文社会科学领域及自然科学领域的关系非常密切；其中国内外人文社会科学领域的被引学科的数量变化不大，而国内外自然科学领域的被引学科数量增长较为明显；国内外被引学科主要集中在与图情学相邻近的几个核心学科中，且国内外学科交叉性呈现出了相反的变化趋势，但总体变化并不明显；具体来看，国内的图情学、新闻与传播学等学科以及国外的图情学、计算机科学—交叉应用、跨学科等学科等具有学科交叉性背景的学科的比例在不断增加。

〔Abstract〕This paper analyzed 13098 articles from 4 core journals of the information science in China from 2006 to 2015 in the CSSCI database in order to reveal the characteristics of the discipline using interdisciplinary index and science overlay map visualization technology.The results showed that the frequency of discipline sources was in accordance with the power-law distribution，the relationship between information science and humanities and social science field and natural science field was very close in domestic and international in the past 10 years；The number of cited subjects in humanities and social science had not changed greatly，but the number of cited subjects in natural science had increased markedly；The cited disciplines domestic and international focused on several core disciplines which close to the information science and library science，and the interdisciplinary domestic and international showed the opposite trend，but the change was not obvious；Specifically，the proportion of domestic subjects such as information science and library science，news and communication science and international subjects such as information science & library science，computer science，interdisciplinary applications，multidisciplinary sciences had been increasing.

情報学是一门交叉性非常强的学科，国内外众多学者从不同角度出发进行了深入研究。早在1968年，Brok就通过研究指出情报科学是一门交叉性的学科，其知识来源非常广泛且与众多学科如数学、逻辑学、语言学、心理学、计算机技术、运筹学、平面艺术学、通信学、图书馆学、管理学等有关[1]，Al-Sabbagh在其1987年的博士学位论文中分析了JASIS期刊1975-1985年文章中的参考文献，发现被引用的出版物来源于各种学科，其中计算机科学、图情学被引用的最为频繁，特别是计算机科……
