结合最近邻指数法、核密度估计法和标准差椭圆分析法，对长江流域高级别旅游景区空间分布特征进行分类型、分地域的交叉互动分析。结果表明：（1）6类高级别旅游景区空间分布类型特征相似，都呈现出凝聚分布状态，但不同类型景区空间分布凝聚程度存在差异。（2）空间分布形态呈条带状分布，中下游地区较上游地区表现出明显的强集聚分布特征。6类旅游景区因所处环境不同，高密度集聚区也存在明显不同。（3）空间分布方向呈明显的东西走向，中下游地区是集中覆盖区。6类景区标准差椭圆覆盖面积由大到小依次为文化古迹遗存类、生物景观类、旅游商品产业类、地文景观类、水域景观类、文化艺术赏析类。（4）长江流域高级别旅游景区的空间分布主要受地形、地势、水文、气候等自然环境因素，以及相关政策支持、经济社会发展、交通设施条件、旅游资源禀赋等人文环境因素的综合影响。

Taking the Yangtze River Basin as the research object, combining the nearest neighbor index method, kernel density estimation method and standard deviation ellipse analysis method, this paper analyzed the spatial structure characteristics of high-level tourist attractions in different types and regions. The research shows that: (1) The characteristics of the spatial distribution types of six high-level tourist attractions in the Yangtze River Basin are similar, and they all show a condensed distribution state, but the condensed degree of spatial distribution of different types of scenic spots is different. (2) The spatial distribution pattern is strip-shaped, and the distribution of scenic spots in the middle and lower reaches is obviously characterized by strong agglomeration than that in the upper reaches. Six types of tourist attractions have different high-density agglomeration areas due to their different environments. (3) The spatial distribution direction is obvious from east to west, and the middle and lower reaches are concentrated coverage areas. The area covered by standard deviation ellipse of the six scenic spots in descending order is: cultural relics, biological landscape, tourism commodity industry, geological landscape, water landscape, and cultural and artistic appreciation. (4) The spatial distribution of high-level tourist attractions in the Yangtze River Basin is mainly influenced by natural environment factors such as topography, topography, climate and hydrology, as well as human environment factors such as relative policy support, economic and social development, transportation facilities and tourism resource endowment.
