文化遗产数字叙事项目因数字媒介的技术性和叙事逻辑的独特性而发挥出新的文化势能。文章以叙事结构、叙事时空、叙事视角构建文化遗产数字叙事项目的叙事逻辑分析框架，对国内外11个文化遗产数字叙事项目进行研究。基于案例分析结果，探讨了文化遗产数字叙事项目的叙事逻辑具有叙事结构的程序性与块茎性、叙事时空的可变性与开放性、叙事视角的在场性与代入感等特征。在此基础上，尝试构建“叙事结构-叙事视角-叙事时空”三维融合的文化遗产数字叙事项目之叙事逻辑体系，提出具有推广潜力的建设策略。研究表明，应采用非线性结构丰富探索路径、借助数智技术实现跨时空对话、增强深度互动打造沉浸式体验，从而提升文化遗产的传播效果和公众认同。

Cultural heritage digital narrative projects exert new cultural potential due to the uniqueness of digital media technology and narrative logic. Constructing the narrative logic analysis framework of cultural heritage digital narrative projects with narrative structure, narrative space-time and narrative perspective, this paper studies 11 typical cultural heritage digital narrative projects at home and abroad. Based on the results of the case study, the narrative logic of cultural heritage digital narrative projects is characterized by the procedural and rhizome nature of narrative structure, the variability and openness of narrative space-time, and the presence and sense of immersion of narrative perspective. On this basis, an attempt is made to construct a narrative logic system for the digital narrative of cultural heritage that integrates "narrative structure narrative perspective narrative time and space" in three dimensions, and to propose construction strategies with potential for promotion. The research results indicate that non-linear structures should be used to enrich exploration paths, cross temporal and spatial dialogue should be achieved through the use of digital intelligence technology, and deep interaction should be enhanced to create immersive experiences, thereby enhancing the dissemination effect and public recognition of cultural heritage.
