Spatial pattern distribution of 3A level and above tourist attractions in Guilin City from 2008 to 2023

Taking 3A-grade tourist attractions in Guilin City as the research object, comprehensively applying the methods of geographic concentration index, nearest-neighbour index, kernel density, accessibility analysis, correlation analysis and buffer analysis, this study explored spatial distribution characteristics of 3A-grade tourist attractions in Guilin City and their evolution characteristics, and judged the influence factors of spatial distribution. The results showed that: ① The number of 3A-grade tourist attractions in Guilin City showed an upward trend from 2008 to 2023, and gradually expanded from clustered distribution to uniform distribution; ② Over time, high-density core areas of 3A-grade tourist attractions were distributed in Qixing District, Xiufeng District, and Yanshan District, forming a distribution characteristic of "single core, secondary core dispersed". ③ The average accessibility time for 3A-grade tourist attractions in Guilin was about 30 minutes, in particular, the accessibility of Guilin's main urban area was better, generally within 15 min. ④ The factors affected the spatial distribution of tourist attractions above grade 3A in Guilin City were: elevation > GDP > Road network core density > water system.
