元宇宙是当前互联网领域最炙手可热的焦点话题，为未来图书馆的建设和发展提供了启发式的理论、方法与技术。文章探讨了图书馆与元宇宙理论融合的缘起、内涵与特征，设计并构建了相应的体系结构，并分别从融合结构、要素、技术与能力等方面进行了阐释，进而对其发展趋势进行了分析。研究认为，图书馆元宇宙作为元宇宙的重要组成部分之一，能全面感知图书馆人、机、物、环境等要素及其彼此之间关联关系，实现图书馆物理世界与元宇宙空间的有效衔接。

Metaverse is the hottest focus topic in the current Internet field, which can provide heuristic theories, methods and technologies for the construction and development of libraries in the future. This paper discusses the origin, connotation and characteristics of the integration of library and metaverse theory, designs and constructs the corresponding system structure, explains it from the aspects of integration structure, elements, technology and ability, and then analyzes its development trend. The research shows that the library metaverse, as one of the important components of the metaverse, can fully perceive the human, machine, material, environment and other elements of the library and their relationship with each other, so as to realize the effective connection between the library physical world and the metaverse space.
