25 Research on the Representation Intensity of Cultural Genes of Longquan Celadon Ewers in the Song Dynasty Based on Analytic Hierarchy Process - Entropy Weight Method（AHP-EWM）

Abstract

This research aims to address the issues of weakened cultural attributes and ambiguous gene-screening criteria in the digital preservation of traditional handicraft intangible cultural heritage. Focusing on Longquan celadon ewers from the Song Dynasty, it proposes a quantitative screening framework for evaluating the representation intensity of cultural genes. Based on the tripartite cultural structure of "material-behavior-spirit", 23 gene elements-such as shape, glaze color, and craftsmanship were analyzed to construct a three-layer gene map. Through two rounds of anonymous expert consultations using the Delphi method (with the recovery rate increasing from 76.47% to 90%), 18 high-representation potential factors are screened out. Subsequently, the ‌AHP-EWM was adopted to calculate comprehensive weights (CR≤0.1), balancing subjective and objective deviations. Results indicate that the material layer carries the highest weight (0.494), among which the Plum Green glaze (0.541) and Bulbous-bellied shape (0.470) exhibit outstanding representation intensity. In the behavioral layer, decorative techniques (0.653) is predominant, while in the spiritual layer, auspicious culture (0.789) emerges as the key gene. This method provides an objective and operable framework for screening cultural genes in intangible cultural heritage, addressing the lack of quantitative evaluation of cultural attributes.
