Spatio-temporal Evolution and Influencing Factors of A-level Tourist Attractions in Gansu Province
The rationality of spatial layout in tourist areas is the fundamental guarantee for the high-quality development of tourism.In this study,the average nearest neighbor index,kernel density estimation method,and standard deviation ellipse were used to investigate the temporal and spatial distribution patterns as well as specific influencing factors of A-level tourist scenic spots in Gansu Province.The findings are as follows.In terms of temporal evolution,the A-level tourist scenic spots in Gansu Province exhibit a spindle-shaped distribution with"fewer at both ends and more in the middle",characterized by two stages of stable growth from 2007 to 2015 and rapid development from 2016 to 2022.Regarding spatial distribution,the A-level tourist scenic spots in Gansu Province demonstrate an agglomerative pattern,with a spatial distribution density following a"double nucleus and multiple growth poles"agglomeration centered on Lanzhou City and Tianshui City.The spatial distribution direction is northwest-southeast,with an elliptical center of gravity trajectory resembling a"Z"shaped movement,consistently located in the northwest of Lanzhou City.Influencing factors affecting the spatial and temporal distribution patterns of A-level tourist scenic spots in Gansu Province are jointly influenced by natural environment,tourism economy,and social policies.Among these factors,the influence of tourism economy holds dominance while the impact of social policies is gradually increasing.The influence of natural environment tends to remain stable.Based on this analysis,a"one core,two wings,and multiple corridors"development concept is proposed as reference suggestions for optimizing the spatial layout of tourism scenic areas and promoting high-quality tourism development in Gansu Province.
