Based on the memorabilia data of Taijiquan culture in Yongnian county,this paper builds temporal and spatial database of Taijiquan culture by using GIS technology to standardize the memorabilia information from the perspective of time,space,audience and theme.According to cultural diffusion theory of cultural geography,different cultural diffusion stages of Taijiquan are divided,and three influence factors of diffusion including the forms and distance of dissemination and the types of disseminators are determined.Then calculation models of impact intensity,annual cumulative impact intensity and city space cumulative impact intensity of single memorabilia are designed.It provides the foundation for temporal and spatial diffusion research of Yongnian Taijiquan culture.The calculation results of the model show that the inner driver of the original place of Yongnian Taijiquan is the core power to make Taijiquan spread to the surrounding areas at small scales.The spreading towards primate cities and big cities is driven both by the inner power of culture and the background of society and history,and it manifests as long-distance diffusion at large scales.This paper adopts the combination of quantitative and qualitative methods to study cultural diffusion,and provides a reference method for the study of cultural geography.
