摘要： DNA作为一种密度极高且持久性强的信息存储载体，在长期保存文化遗产数据方面具备巨大的潜力。本文通过形象的语言探讨利用DNA存储技术将敦煌壁画转化为DNA序列，利用双层错误校正码和de Bruijn图算法确保数据的稳定性和恢复性。并利用“细胞磁盘”作为存储介质，有望实现DNA数据的高密度和长期存储，激发读者了解前沿科技的兴趣。

Abstract: DNA, as a highly dense and durable information storage medium, holds significant potential for the long-term preservation of cultural heritage data. This paper explores the process of converting data from the Dunhuang murals into DNA sequences using DNA storage technology, highlighting the application of dual-layer error correction codes and de Bruijn graph algorithms to ensure data stability and recoverability. Furthermore, the use of “cell disk” as a storage medium is expected to enable high-density and long-term DNA data storage. The goal is to inspire readers to engage with and explore cutting-edge technologies.

Key words: DNA storage, Mural protection, Prospects and challenges
