广西健康旅游地时空分布格局及其影响因素

Spatial and Temporal Distribution Patterns and Influencing Factors of Health Tourism Destinations in Guangxi

借助Arcgis、SPSS工具,运用最邻近点指数分析法、核密度估算法和标准差椭圆分析法,从时间和空间维度对广西健康旅游地的分布进行探究。结果显示:(1)健康旅游地数量逐年快速增长,自2017年后出现“井喷式”增长,健康旅游地的种类由单一化向多样化转变,以度假养生类旅游地为主,其他类型旅游地逐渐增多;(2)除中医药类健康旅游地呈离散分布外,其他类型均为聚集分布,以桂林—柳州—南宁形成“三点一线”的高密度核心区,并从高密度区逐渐向周边辐射带动发展,空间上由“少核”逐渐转为“多核”密度区的聚集模式,椭圆重心向东移动,大致呈现西南—东北的分布趋势;(3)广西健康旅游地时空演化特征主要受自然资源、交通、政策和经济等因素的影响。

Using ArcGIS and SPSS tools,the nearest neighbor index analysis method,kernel density estimation method and standard deviation ellipse analysis method are used to explore the distribution of health tourism destinations in Guangxi from the time and space dimensions.The results show that:(1)The number of health tourism destinations has been growing rapidly year by year.After 2017,there has been a“blowout”growth.The number of vacation and health care tourism destinations is increasing,so are the other types,thus,the types of health tourism destinations have changed from simplification to diversification.(2)All types are clustered except Traditional Chinese Medicine Health tourism destination which is discretly distributed.Guilin-Liuzhou-Nanning forms a high-density core area of“three points and one line”,and gradually radiates from the high-density area to the surrounding area.Density aera,spatially shifting from“fewer nuclei”to“multi-nucleus”density area,the ellipse s center of gravity moves eastward,roughly presenting a southwest-northeast distribution trend;(3)The spatio-temporal evolution characteristics of Guangxi healthy tourism destinations are mainly affected by factors such as natural resources,transportation,policies and economy.
