Study on Spatio-temporal Evolution Characteristics and Its Influencing Factors of A-level Tourist Attractions in Gansu Province
In order to study the spatial and temporal distribution characteristics of A-level tourist attractions in Gansu Province,this paperstudies the spatial and temporal distribution characteristics and influencing factors of A-level tourist attractions in Gansu Province from 2012 to 2023 based on nearest neighbor index,geographical concen-tration index,nuclear density analysis,gravity shift and random forest model.The results show that:The number of A-level tourist attractions in Gansu Province from 2012 to 2023 has increased steadily.The spatial distribution of A-level tourist attractions in Gansu Province shows the overall distribution pattern of"chain bead,two-level multi-core",and the distribution density of tourist attractions in southeast region is relatively concentrated.From 2012 to 2023,the center of gravity of the spatial distribution of A-level tourist attractions shifted from northwest to south-east.The number of tourists arrivals,the number of star-rated hotels and the annual cumulative precipitation are three important positive factors in the distribution pattern of A-level tourist attractions in Gansu Province.Tempera-ture and altitude are the two major constraints.The research results can provide theoretical support for optimizing the spatial layout of regional tourism resources.
