Abstract: Rural public cultural space is the core carrier of memory preservation and identity cohesion, and its innovative construction is crucial to rural cultural revitalization. Based on the theory of cultural memory, this paper constructs a four-dimensional interactive analytical framework of ‘carrier-form-function-space', clarifying that rural memory is an organic unity of communicative memory (local memory) and cultural memory (historical memory), which form a dynamic connection through ‘carrier overlap-content complementarity-function coordination'. Drawing on the theory of cultural gene, a three-stage spatial translation path of ‘symbolic translation-narrative reconstructioncommunity symbiosis' is proposed. Combined with the three-level public cultural space network of ‘core-productionliving', the coordinated development of memory activation and rural revitalization is realized. Taking Xiaoxi Village, Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province as a case study, through literature review, field investigation and spatial analysis, this paper sorts out its memory formation context of ‘military migration-clan settlement-daily evolution', deconstructs the carriers, forms, functions and spatial translation logic of rural memory, and provides a practical paradigm for rural memory protection and public space innovative design in traditional villages.
