[目的/意义] 数据管护是信息化科研环境下研究数据管理的重要部分，梳理国际已有相关研究成果，以期全面认识数据管护，为国内数据管理研究提供参考。[方法/过程] 以Web of Science为数据源，检索时间截至2016年10月，检索词为数据管护，将检索到的文献作为研究对象，基于文献共现和共被引分析方法，利用CiteSpaceⅢ软件工具，绘制国际数据管护的知识图谱，采用内容分析法，基于研究的学科分布、研究机构、研究人员以及知识基础的4个维度，对国际数据管护研究进行解读、分析与总结。[结果/结论] 国际数据管护研究始于2000年，已经步入成熟期，并形成特定的研究学科、机构和群体，研究的知识基础主要为数据描述、集成与关联、科研过程的数据维护和增值活动、数据管护利益相关者以及图书馆服务新模式。

[Purpose/significance] Digital Curation (DC) is an important part of research data management in e-Science environment. By systematically combing the research progress and proposing some issues worthy of further studying, this paper aims to provide a basis and reference for national research data management research. [Method/process] Documents relevant to data curation were retrieved from Web of Science database. With CiteSpace Ⅲ software based on the document co-citation analysis method, this paper drew the knowledge map of international digital curation. In terms of research-based subject distribution, research institutions, researchers and knowledge of the four dimensions, the related contents were analyzed and summarized with the content analysis method. [Result/conclusion] International digital curation research began in 2000. Now it has entered a mature period, with a specific research disciplines, institutions and groups. The research’s knowledge base is data description, integration and association, data maintenance in the scientific research process and value-added activities, data management stakeholders and service innovation models of library services.
