昆明市休闲旅游资源空间分布特征及成因分析

Analysis of the Spatial Distribution Characteristics and Causes of Leisure Tourism Resources in Kunming

在地理时空兴趣点(POI)数据基础上,利用空间自相关和地理探测器等原理和方法,分析了昆明市休闲旅游资源的空间分布特征.结果表明:昆明市休闲旅游资源空间分布特征差异明显,表现出南多北少、城区多郊区少以及“中心—外围”扩散分布等特征.同时,昆明市休闲旅游资源分布特征具有显著的空间自相关性,南部高—高和北部低—低聚集趋势明显,二者聚类区域合计占比30%,表现出明显的空间聚集特征.经济、社会、人口和空间距离等因素是影响昆明市休闲旅游资源空间分布的主要因素,其中第三产业比重与人口密度的交互影响力要明显大于任一单因子及其他因子交互的影响力.

On the basis of geographic spatiotemporal Point of Interest(POI)data, the spatial distribution characteristics of leisure tourism resources in Kunming are analyzed by using the principles and methods of spatial autocorrelation and geographic detector.The results show that there are obvious differences in the spatial distribution characteristics of leisure tourism resources in Kunming.At the same time, the distribution characteristics of leisure tourism resources in Kunming have significant spatial autocorrelation.The trend of high-high in the south and low-low in the north is obvious.The total clustering areas of the two regions account for 30%,showing obvious spatial clustering characteristics.Economic, social, demographic and spatial distance are the main factors affecting the spatial distribution of leisure tourism resources in Kunming.The interaction between the proportion of the tertiary industry and population density is significantly greater than that of any single factor and other factors.
