云南省A级旅游景区空间分异演化特征及影响因素

Spatial Differentiation Evolution Characteristics and Influencing Factors of A-level Tourist Attractions in Yunnan Province

基于2009年、2015年和2021年三个时点,运用最近邻指数、核密度分析、标准差椭圆方法对云南省A级景区空间分布及演化进行分析,在此基础上选取五个方面8个变量探索空间分异的驱动因素。研究结果表明:云南省A级景区数量在三个时点上递增,不同等级景区逐渐呈“纺锤形”结构;空间分布上呈集聚模式,2015年后景区分布趋向优化;核密度中心呈“单核心—多核心—双核心”的空间演化规律;空间分布方向性逐渐明显,呈“西北—东南”走向;不同时点驱动因素对空间分异的影响程度不同,两个因素交互作用效果优于单个因素。

Based on the three years of 2009, 2015 and 2019, the spatial distribution and evolution of Alevel tourist attractions in Yunnan province were analyzed by using the nearest neighbor index, kernel density analysis and standard deviation ellipse method. On this basis, eight variables from five aspects are selected to explore the influencing factors of spatial differentiation. The results show that: the number of A-level tourist attractions in Yunnan province increases at the three years, and different levels of tourist attractions gradually show a“spindle”structure;the spatial distribution shows an cluster pattern, and the distribution of tourist attractions tends to be optimized after 2015;the spatial evolution of nuclear density centers is“single-core to multi-core to double core”;the direction of spatial distribution is gradually obvious, showing a“northwest to southeast”trend;the influencing factors at different years had different effects on spatial differentiation, and the interaction effect of two factors was better than that of a single factor.
