以内蒙古自治区517个高等级文化旅游资源点为研究对象,基于GIS的最近邻指数、核密度估计等空间分析方法与地理探测器手段分析了内蒙古高等级文化旅游资源空间分布特征及影响因素。研究发现:(1) 内蒙古高等级文化旅游资源总量丰富,三种类型中以人类活动类数量最多,遗迹遗址类数量最少;(2) 内蒙古高等级文化旅游资源空间分布呈现出以“呼包鄂”为中心的高密度区,以及以各个盟市主城区为中心的次级密度区,三种类型的文化旅游资源分布具有不同特征;(3) 影响因素中GDP对文化旅游资源集聚程度的影响最显著,地形、水系、交通也在不同程度上影响了内蒙古高等级文化旅游资源的分布特征。Taking 517 high-grade cultural tourism resource sites in the Inner Mongolia Autonomous Region as the research object, the spatial distribution characteristics and influencing factors of high-grade cultural tourism resources in Inner Mongolia were analyzed based on the spatial analysis methods such as nearest-neighbor index, kernel density estimation and geodetic detector means of GIS. It is found that: (1) the total amount of high-level cultural tourism resources in Inner Mongolia is rich, and among the three types, the human activities category has the largest number, while the relics and sites category has the smallest number;(2) the spatial distribution of high-level cultural tourism resources in Inner Mongolia shows a high-density area centered on “Hubao and Egao”, and a sub-density area centered on the main urban areas of each league city. The distribution of the three types of cultural tourism resources has different characteristics;(3) Among the influencing factors, GDP has the most significant influence on the degree of concentration of cultural tourism resources, and topography, water system and transportation also affect the distribution characteristics of high-level cultural tourism resources in Inner Mongolia to different degr
