近年来跨媒介青年旅行叙事的兴起，成为当代文学创作和文化现场的新现象。这一方面源于后疫情时代的“旅行热”现象，另一方面则源于旅行叙事与青年主体生成密切相关。本文聚焦于当代青年旅行叙事，探讨旅行叙事与青年文化身份及其自我想象之间的关系。论文从“空间想象”“风景修辞”“情感认同”和“媒介叙事”等四个层面介入跨媒介的典型文本和文化现象。在“空间想象”中，论文从精神分析的角度切入，指出旅行的空间想象具有疗愈效果，个体生命经验得以安放；在“风景修辞”中，论文指出三种风景修辞：如画风景、风景转喻与风景层累，认为其体现了个体的回避和游移状态；在“情感认同”中，论文从“离散”与“脱嵌”切入，指出当下青年的情感结构变化和自我身份认同；在“媒介叙事”中，论文从“景观”和“仿真”切入，认为跨媒介的旅行vlog叙事造成了个体经验的同质化。总之，经由对旅行叙事的研究，论文发现当代青年在走向世界的时刻，一方面携带着解决时代问题的思考和努力，另一方面也呈现出对个体经验的强调，囿于自我的疆域。

The rise of cross-media youth travel narratives in recent years has become a new phenomenon in contemporary literary creation and cultural scene. This is partly due to the phenomenon of travel fever in the post-epidemic era, and partly due to the fact that travel narratives are closely related to the generation of youth subjects. This paper focuses on contemporary youth travel narratives and explores the relationship between travel narratives and youth cultural identity and self-imagination. The thesis focuses on four dimensions: spatial imagination, landscape rhetoric, emotional identity and media narrative. The thesis intervenes in the typical texts and cultural phenomena of transmedia. In Spatial Imagination, the thesis starts from the perspective of psychoanalysis, pointing out that the spatial imagination of traveling has a healing effect, and the individual life experience can be placed; in Rhetoric of Landscape, the thesis points out that there are three kinds of rhetoric of landscape, namely, Picturesque Landscape, Landscape Metaphor and Landscape Layering, and argues that they embody the individual life experience. In the Rhetoric of Landscape, the thesis points out three kinds of landscape rhetoric: picturesque landscape, landscape metaphor and landscape layer accumulation, and considers that they reflect the state of avoidance and wandering of the individual; in the Emotional Identity, the thesis starts from the Diaspora and Disembedding, and points out that the change of the emotional structure of the youth and their self-identity are the main reasons for the change. In Media Narrative, the thesis starts from landscape and simulation, and argues that cross-media travel vlog narratives have caused the homogenization of individual experiences. In conclusion, through the study of travel narratives, the thesis finds that when contemporary youth go out into the world, they carry the thinking and efforts to solve the problems of the times on the one hand, and on the other hand, they also emphasize their individual experiences and are confined to their own boundaries.
