Research on the Diffusion and Evolution of Ethnic Traditional Sports Culture Based on Spatial Diffusion Modeling

In the long history of five thousand years, various ethnic groups in China have created wonderful traditional sports programs, such as archery, horseback riding, martial arts, dragon boat racing, etc., which have formed a national sports culture with profound humanistic values and aesthetic connotations. The study first constructs a spatial diffusion model based on the GIS field model and object model and extracts the cultural spatial diffusion pattern. Then, taking Yang-style Taijiquan, a national traditional sports culture, as the research object, a spatiotemporal database of events is constructed to visualize the spread of this culture. Finally, we explored the differences in the evolution of Yang-style Taijiquan in cities of different sizes and aging levels through ANOVA. Yang-style Taijiquan has significantly more gyms in large cities than in small cities (P<0.05), which is more advantageous for development. With the aging level deepening, the demand for Yang-style Taijiquan among older people showed an inverted “U” pattern, indicating that Yang-style Taijiquan has some limitations in coping with the higher aging level.
