“…With the depth of the study, the focus of scholars shifted to a higher level of analysis concerning influencing factors. Scholars generally believe that population density, economic level, government capacity, and scientific and technological investment are the main factors affecting tourism-related ecological security [29,30], usually with the help of the gray correlation projection method [31], barrier degree model [32], geographic detector [33], structural equation modeling [34], etc., and the large quantity of practical evidence that has been collected. The research objects involve watersheds [35,36], provinces [36], cities [37][38][39], parks [40,41], scenic areas [42,43], islands [44,45], and mountains [46,47].…”
