Intelligent Deduction and Historical Reconstruction an AIGC-Driven Exploration of the Main Hall Ruins at Gonghoulong Temple, Ningde, China

Abstract. This research explores the innovative application of Artificial Intelligence Generated Content (AIGC) technology in the digital restoration of ancient architectural ruins. It focuses on the unique architectural tradition of Song Dynasty single-bay Buddhist halls in the Changxi River Basin of eastern Fujian, using the Gonghoulong (宫后垄) Temple site in Ningde City, Fujian Province, as a case study. The study pioneers a collaborative research paradigm that integrates architectural archaeology with generative artificial intelligence. Through precise digital surveying and multi-source literature verification, we analyze the spatial organization of stone components at the site, revealing that the Song Dynasty Buddhist Hall at Gonghoulong Temple incorporates layered pavilion concepts, demonstrating distinctive regional characteristics that differ from official architectural practices. By leveraging AIGCpowered intelligent deduction, the study establishes a "digital archiving-intelligent deduction-dynamic intervention" restoration framework through stylized generation and virtual reconstruction simulations. The Gonghoulong Temple site, discovered in the late 20th century, contains significant architectural remains such as house foundations, ash pits, and tombs. The Changxi River Basin preserves numerous Tang-Song period single-bay Buddhist Hall ruins, indicating a unique regional architectural pattern seldom seen in Chinese history. This technological exploration aims to revive the "single-bay pavilion-style" construction wisdom of the Changxi Basin. Through digital analysis and architectural form recombination, it facilitates the virtual restoration of the Song Dynasty Buddhist Hall at Gonghoulong Temple, offering new insights into early Buddhist architecture along China's southeastern coast and establishing standardized references for the intelligent conservation of similar heritage sites across East Asia.
