目的 以成昆铁路文创产品为研究对象，探究设计方法与流程，为铁路工业遗产的传承与延续提供新思路。方法 从集体记忆的视角出发，首先根据记忆理论探究集体记忆的产生机制;其次结合感质理论方法，搭建以“感官记忆”“行为记忆”“情感记忆”“反思记忆”四层级构成的集体记忆建构模型;随后以成昆铁路攀枝花段为例，利用层次分析法提取出设计因子;最后通过设计实践验证研究的有效性。结论 传承和保护铁路工业遗产对弘扬民族精神、坚定文化自信有重要意义。集体记忆视域下的成昆铁路文创设计能帮助设计师挖掘用户的集体记忆需求，协助用户了解成昆铁路线的历史过往和精神内涵，进而实现用户的记忆认同。

The work aims to take the Chengdu-Kunming Railway's cultural and creative products as a research object, delve into the design method and process, and propose new ideas for the inheritance and preservation of railway industrial history. The study investigated the generation mechanism of communal memories based on the memory theory. Second, it employed the sensory quality theory method to create a collective memory creation model with four levels:"sensory memory, behavioral memory, emotional memory, and reflective memory". Then, with the Panzhihua section of Chengdu-Kunming Railway as an example, the design factors were extracted by hierarchical analysis. Finally, the research's effectiveness was validated through design practice. It is discovered that the inheritance and protection of railroad industrial heritage is of great significance in carrying forward the national spirit and firm cultural confidence. The cultural and creative design of the Chengdu-Kunming Railway from the perspective of collective memory can assist designers in tapping into users' collective memory needs, helping users understand the history and spiritual connotation of the Chengdu-Kunming Railway, and then realizing users' memory identities.
