粤港澳大湾区星级酒店空间分布特征

Spatial Distribution of Star Hotels in Guangdong-Hong Kong-Macao Greater Bay Area

星级酒店是城市发展的重点体现,明确星级酒店在城市内部的发展特征,空间分布及区位分布可为城市建设提供指导意见.本文以粤港澳大湾区为研究区域,基于POI数据并运用核密度分析和空间自相关性分析方法,探究了粤港澳大湾区11个城市2017年三星级酒店、四星级酒店和五星级酒店的空间分布特征,研究了粤港澳大湾区星级酒店的空间集聚性和自相关性.结果表明,粤港澳大湾区星级酒店的空间分布具有不平衡性.在大陆地区,星级酒店主要集中分布在广州、深圳,形成一级集聚区,并从城市中心向城市外延呈"环形放射状"递减分布;在港澳地区,以香港和澳门为大核心形成高密度区,从沿海向内陆星级酒店呈"扇形扩张状"的增加分布.此外,粤港澳大湾区不同类型星级酒店的空间分布具有差异,在空间上呈现显著正相关性,形成高高、高低、低高、低低四种集聚类型.

Star hotels are the focus of urban development.Defining the development characteristics of star hotels within the city,spatial distribution and location distribution can provide guidance for urban construction.This paper takes Guangdong-Hong Kong-Macao's Greater Bay Area as the research area.Based on POI data and used nuclear density analysis and spatial autocorrelation analysis methods,the spatial distribution characteristics of three-star hotels,four-star hotels and five-star hotels in 11 cities in Guangdong-Hong Kong-Macao's Greater Bay Area are explored.The spatial agglomeration and autocorrelation of star hotels in Guangdong-Hong Kong-Macao's Greater Bay Area were studied.The result shows that the spatial distribution of star hotels in Guangdong-Hong Kong-Macao's Greater Bay Area is uneven.The star hotels in the land part are mainly concentrated in Guangzhou and Shenzhen,and form a first-level gathering area with a decreasing distribution of"circular radial"from the center of the city to the edge of the city;The star hotels in Hong Kong and Macao area,taking Hong Kong and Macao as the core,star hotels form a high-density area with the increased distribution of"fan-shaped expansion"from coastal to inland.In addition,there are some difference in the spatial distribution of different types of star hotels in Guangdong-Hong Kong-Macao's Greater Bay Area.It exhibits a significant positive correlation in space and forms four types of agglomeration: high-high,high-low,low-high and low-low.
