基于地理探测器的甘肃省A级旅游景区空间分布与影响因素

利用空间分析技术与地理探测器模型，以甘肃省443个Ａ级旅游景区为研究对象，采用平均最近邻指数、核密度估计等方法，研究甘肃省Ａ级旅游景区的空间分布特征。在此基础上，运用地理探测器模型识别和分析影响甘肃Ａ级旅游景区空间分布特征的因素。研究表明，甘肃省A级旅游景区空间聚集效果显著，但空间分布均衡度较低。不同等级类型景区集聚程度存在差异，景区在以嘉峪关、张掖等市州形成分布较为密集的中心旅游圈，甘肃Ａ级旅游景区空间分布格局的形成受自然资源、社会环境、经济活力的共同影响，三者相比而言，经济活力指标对景区空间分布作用强度更大。

Spatial Distribution Characteristics and Influencing Factors of A-grade Tourist Attractions in Gansu Province Based on the Geographic Detector

Using spatial analysis techniques and geographic detector models, Taking 443 A-level tourist attractions in Gansu province as the research object, and the spatial distribution characteristics of A-level tourist attractions were discussed by means of average nearest neighbor analysis, kernel density estimation and other methods. On this basis, The factors affecting the spatial distribution of A-level tourist attractions in Gansu province were identified and analyzed by using the geographical detector model. The results show that the spatial aggregation effect of A-level tourist attractions in Gansu province is significant, but the spatial distribution balance degree is low. There are differences in the degree of agglomeration among different types of scenic spots. The scenic spots form the center tourism circle with dense distribution in cities and states such as Jiayuguan and Zhangye. The formation of spatial distribution pattern is influenced by natural resources, social environment and economic vitality, which have a stronger effect on the spatial distribution of scenic spots.
