甘肃省A级旅游景区时空演变特征及其影响因素研究

Study on Spatio-temporal Evolution Characteristics and Its Influencing Factors of A-level Tourist Attractions in Gansu Province

为研究甘肃省A级旅游景区时空分布特征,文章基于最近邻指数、核密度分析、重心迁移、随机森林模型对甘肃省2012—2023年A级旅游景区时空分布特征及影响因素展开研究。研究结果表明:2012—2023年甘肃省A级旅游景区数量呈稳步增长的态势;甘肃省A级旅游景区的空间分布整体呈“链珠式,两级多核”的分布格局,且东南区域旅游景区分布密度较为集中,A级旅游景区空间分布的重心自2012—2023年大致沿西北向东南方向发生迁移;游客接待人次、星级酒店数量和年累计降水量是甘肃省A级旅游景区分布格局中3个重要的正向因子,而温度和海拔是2个制约因素。研究结果可为优化区域旅游资源空间布局提供理论支持。

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.
