Spatial-temporal pattern of cultural heritage along the Sichuan Tibet railway and influencing factors

This is the authors' abstract. We don't add key points for this paper.

Since ancient times, the Sichuan-Tibet Railway corridor has given birth to a wealth of cultural heritage. This study employs GSA, ESTDA, and OPGD to investigate the spatial patterns and influencing factors of cultural heritage in counties along the Sichuan-Tibet Railway. The results show that: (1) The quantity and spatial pattern of cultural heritage in counties along the Sichuan-Tibet Railway have dynamically changed over time, exhibiting a quasi-periodic characteristic of weak agglomeration—strong agglomeration—weak agglomeration. (2) The local spatial structure of cultural heritage quantity and the overall fluctuation amplitude of spatial dependency direction are small, indicating strong spatial integration. The local spatial autocorrelation structure is relatively stable, with evident transfer inertia and path dependency, and significant regional coordinated development relationships, especially in the areas at both ends of the railway. (3) The spatial pattern of cultural heritage along the route is the result of the interaction of multi-factor, especially historical and cultural factors. The research results have practical value for the excavation, protection and utilization of cultural heritage resources along the Sichuan-Tibet Railway.
