：文章检索了1949年以来我国与用户信息行为相关的研究成果，通过共词分析、聚类分析和战略坐标图等方法，归纳了不同阶段我国用户信息行为研究的热点主题及其关联，揭示了研究热点主题随时间变化的演化脉络。研究结果表明，信息行为最初主要集中于对图书文献存储、检索与利用情况的调研，随着认知科学的引入，其研究的重点开始转向以用户为中心，且其研究热点如研究的信息行为主体、信息行为类型、信息行为环境、信息行为范围、研究方法等随时间推移发生了明显的演化。

In order to help scholars sort out and clarify the evolution of the hot spots of users' information behavior research in China, a detailed search and literature review of the studies relevant to users' information behavior  since 1949 was conducted, systemically summarized the research hot spots in different periods and the evolution of these hot spots, proposed the future research directions of users' information behavior by the analysis methods of co-words, cluster and strategic diagram. It is found that Chinese information behavior research initially focused on the investigation of the storage, retrieval and utilization of books. With the introduction of cognitive science, the research focus has turned to users, and its research hot spots have evolved significantly over time. For example, the information behavior subjects, types, environments, scopes, research methods etc. have all changed.
