：场景式服务是图书馆适应新时代发展的需要，体现了图书馆对用户体验的重视，对服务环境和质量的提升。文章结合相关研究，阐述相关概念与内涵，并从用户、图书馆和知识三个维度分析场景式服务需求。基于此，文章从情景数据采集、情景计算、情景建模、模型评估等分析情景感知模型的构建过程，搭建以用户为中心，由情景感知模块、资源整合模块、技术支撑模块、场景服务模块构成的智慧图书馆场景式服务体系框架，并探讨其中存在的问题与对策。

The scene-based service is the need of the library to adapt to the development of the new era, which reflects the library's emphasis on the user experience and the improvement of the service environment and quality. This paper combines relevant research, expounds related concepts and connotations, and analyzes the scene-based service requirements from the three dimensions of reader, library and knowledge. Based on this, the article analyzes the construction process of context awareness model from context data collection, context calculation, context modeling and model evaluation, and builds the framework of the smart library scene-based service system focuses on users, which consists of context awareness module, resource integration module, technical support module and scene service module, and discussed the problems and countermeasures.
