Abstract: Under the background of digital village development strategy, '5G+' digital technology provides new opportunities for the cultural protection and inheritance of traditional villages. In the face of the traditional village application scenarios, there are many problems, such as wide but not deep, the scenario support not being flexible enough, and the risk of digital technology getting stuck. From the perspective of the whole life cycle of traditional village digitalization, the study constructs a coupling mechanism between traditional village and digital twins in the process of development, change, iterative development, integration and regeneration, and activation, so as to realize the visualization, monitoring, diagnosis, decision-making, interaction, and experience of traditional villages. Based on the differential demand analysis of application scenarios, summarize and refine the basic digital content and expand the digital content framework. Combined with the whole life cycle process, digital methods of digital acquisition, processing, operation and maintenance are proposed. Through the construction of digital content and implementation methods of traditional village application scenes, it provides theoretical support for the digital protection and inheritance of traditional villages.
