【摘要】 白登山作为北魏国家认同建构的重要载体，其机能变迁深刻反映出胡汉文明的交融历程。汉晋时代，白登山主要作为中原王朝与北方游牧民族的交锋前沿，具有极为重要的战略地位，北魏定都平城，继承其传统的军事防御职能，开展校猎阅兵行动，并在国家祭祀体系中兼容北土旧俗与中原礼制，白登山的祭祀与文化象征意义逐渐凸显。孝文帝南迁洛阳，停罢平城祖庙，白登山的祭祀功能趋向退化，然其军事价值在北朝后期的政权更迭中得以延续。隋唐时代，白登山重新归入汉地，成为边塞诗歌书写的地名意象。其政治文化机能的演变不仅反映出北魏统治者对草原游牧传统与华夏文明礼仪的包容与整合，亦见证拓跋鲜卑政权由部族联盟向封建王朝的转型与发展，更为构建北魏国家认同奠定了坚实的基础。更多还原

【Abstract】 As a crucial vehicle for state identity construction in the Northern Wei Dynasty, the functional transformation of Baideng Mountain profoundly reflects the interplay between nomadic and agrarian civilizations. During the Han and Jin periods, Baideng served primarily as a strategic frontier between the Central Plains dynasties and northern pastoral tribes. After the Northern Wei established its capital at Pingcheng, the mountain retained its traditional military-defensive role, hosting drills and troop inspections. Simultaneously, it became integrated into the state sacrificial system, blending northern ancestral traditions with Central Plains rites, thereby amplifying its ritual and cultural symbolism. Following Emperor Xiaowen’s relocation of the capital to Luoyang, the ancestral temple in Pingcheng was abolished, diminishing Baideng’s religious function. Nevertheless, its military significance persisted through the regime changes of the late Northern Dynasties. In the Sui and Tang eras, Baideng Mountain reverted to Han territory, evolving into a toponymic motif in frontier poetry. This evolution not only mirrors the Northern Wei rulers’ synthesis of steppe traditions and Huaxia rituals but also epitomizes the Tuoba Xianbei regime’s transition from tribal confederacy to feudal state, ultimately laying the foundation for Northern Wei’s state identity.更多还原
