以中国知网( CNKI)和万方数据所提供的题录信息为统计数据源，运用文献统计学的分析方法，从9种情报学核心期刊所刊载的全部文献中筛选出了470篇其他学科理论与方法在情报学研究中应用的文献，并依据《中国图书馆图书分类法》的原理对这些文献分类统计，识别出了近年来应用于情报学领域的学科方法。结果表明，数据库和网络技术成为当前情报学研究的热点；数学模型方法被大量应用于情报学的研究；哲学是情报学研究的指导思想；系统科学对情报学研究影响深刻；计算机信息技术成为有力的支撑。%Based on the reference information which is offered by CNKI andWanFang Data as the source of the statistics and the bibliomet-rics method, this paper selected 470 articles about multi-disciplinary theory and method applied in information science from 9 core journals of information science. According to Chinese Library Classification principle, disciplinary theories and methods applied in information sci-ence were identified. The result shows that:database and network technologies become the research focus;philosophy is the guiding ideol-ogy of information science;more mathematical theory, model and method are applied in information science;systems science shows a pro-found influence to information science;computer and information technologies give strong support to information science.
