Construction and Application of Cultural Gene Library of Ancestral Hall in Canton Region

: Ancestral halls in Canton region are an important part of culture and architectural art in Canton region. Currently, research mostly analyzes from the perspective of clan culture and architectural crafts, and rarely explores architectural characteristics and inheritance from the perspective of cultural gene and constructs the gene map of architectural culture. Taking the theory of cultural gene as the starting point, this paper extensively studies the cultural background and inheritance process of cultural genes of ancestral halls in Canton region through literature research and field research. Based on the thinking method of gene reverse transcription in biology and the cultural three-level hierarchy, the main cultural factors were extracted and classified to establish the cultural gene library, gene hierarchical diagram and gene maps of Cantonese ancestral halls. The Analytic Hierarchy Process method (AHP) was used to screen and rank the cultural factors analyzing their importance in all levels in the cultural gene hierarchical diagram. To summarize, this paper discussed the development and evolution of cultural factors of Cantonese ancestral halls and their contemporary inheritance requires more attention on the innovative translation design of core cultural factors with higher importance, based on the principle of authentic and integral preservation of original, providing new perspective and decision-making references for the inheritance of ancestral halls in Canton region.
