元宇宙快速发展正在影响着文旅行业的变革。文旅行业强调创意与场景体验，文旅产品具有重内容、重体验、重参与、重个性化的特点，这与元宇宙的发展高度契合。现阶段，文旅元宇宙的研究还处于襁褓阶段，对文旅元宇宙的概念、核心技术、应用场景还处于探索中。论文首先回顾了元宇宙的演化进程，并基于文旅行业特征，提出了文旅元宇宙的基本定义、概念模型及主要特征。认为文旅元宇宙是元宇宙的一个子系统，是现有信息技术在文旅行业深度融合形成的文旅互联网形态，是文旅活动在三维数字世界的一种重构和虚拟共生。它基于扩展现实技术提供文旅场景的沉浸式体验，基于数字孪生技术生成现实世界文旅场景的镜像，并依托元宇宙统一架构下的政治、经济、文化等体系，实现文旅行业虚拟世界和现实世界的全方位融合。然后对文旅元宇宙相关关键技术在文旅行业应用的研究进展和应用进行了详细的描述。最后展望了文旅元宇宙在文化遗产数字化与保护、景区（酒店）开发与管理、导游导览服务、文旅营销、行业监管与市场治理等方面可能的应用场景，提出了文旅元宇宙未来重点的研究方向。虽然文旅元宇宙的发展还面临着诸多的挑战，技术的发展还要不断地经历螺旋式的上升，但是元宇宙终会重塑未来的社会形态和人类的生活方式。

The cultural tourism industry emphasizes creativity and scene experience, which is highly compatible with the metaverse. The research of the cultural tourism metaverse is in the infancy stage. The concept, key technologies, and application scenarios are still being explored. Firstly, the paper reviews the evolutionary process of the metaverse. The basic definition, conceptual model, and main features of the cultural tourism metaverse are proposed. The paper considers the cultural tourism metaverse as a subsystem of the metaverse. It is a cultural tourism Internet form formed by existing information technology in the cultural tourism industry. It is a reconfiguration and virtual symbiosis of cultural tourism activities in a three-dimensional digital world. It provides an immersive experience of cultural tourism scenes based on extended reality technology. Based on the digital twin technology, it generates a mirror image of the real-world cultural tourism scene. And relying on the political, economic, and cultural systems under the unified architecture of the metaverse, it realizes the all-around integration of the virtual world and the real world of the cultural tourism industry. The conceptual model of the cultural tourism metaverse consists of key technologies, guarantee systems, participating subjects, and product services. The development of the cultural tourism metaverse cannot be achieved without the support of key technologies. As an industry metaverse application, it does not exist in isolation. Its smooth and reliable operation is closely related to the social, political, economic, cultural, legal and moral system established by the future holistic metaverse. The participating subjects of the cultural tourism metaverse include suppliers, consumers, developers, governors and researchers. It is immersive, interactive, customized, cultural, educational, connected, and interdisciplinary, etc. Secondly, the paper summarizes the research progress and application of key technologies in the field of cultural tourism. These key technologies include basic support technologies (such as intelligent communication, internet of things perception, artificial intelligence, positioning and navigation, big data computing and storage), virtual-real connection technologies (such as virtual geographic environment, digital twin, virtual digital human, decentralization) and virtual-real interaction technologies (such as extended reality, brain-computer interface and video games). The cultural tourism metaverse involves far more information technologies than what is mentioned in the paper. Moreover, all information technologies developed so far in the real world will be reflected in future metaverse scenarios or continuously upgraded and improved. Lastly, we look forward to the application scenarios of the cultural tourism metaverse. Such as cultural heritage digitization and protection, scenic spot (hotel) development and management, guided tour service, cultural tourism marketing, industry supervision, etc. The paper argues that the Lfuture research directions of the cultural tourism metaverse include personalized construction of cultural tourism virtual scenes, rapid migration of existing virtual reality cultural tourism scenes, integration of virtual and real cultural tourism scenes, seamless positioning and navigation of the cultural tourism metaverse, visitor experience and interaction, business models and monetization, and interoperability standards for virtual and real cultural tourism scenes. Metaverse development also faces issues such as ethics, security and privacy, technology, and the challenge of realistic national sovereignty. While technology is always hovering, these technologies will eventually reshape the future shape of society and human life.
