| As a special economic zone in China,tourism has always been one of the pillar industries in Hainan Province.And as an important part of the tourism industry,hotel development is an important indicator of tourism capacity and tourism development in any region.Exploring the spatial layout evolution of hotels in Hainan Province and its influencing factors has certain theoretical value and practical significance for the planning layout of hotel industry development in Hainan Province.Based on the POI data of hotels in Hainan Province crawled by Gaode Map and combined with the network big data such as Ctrip.com and Go.com,this thesis selects the hotels with economy,comfort,high-end and luxury grades as the research objects,and selects the hotel data of each year in 2000,2005,2010,2015 and 2020 respectively,and uses nearest neighbor index,kernel density analysis,and ellipse standard deviation analysis Arc GIS spatial analysis methods,such as nearest neighbor index,kernel density analysis,and ellipse standard deviation analysis,are used to reveal the spatial clustering characteristics and location patterns of hotels in Hainan Province,and to explore the spatial and temporal evolution characteristics of hotels in Hainan Province from 2000 to 2020 and the trajectory of their center of gravity.On this basis,the influencing factors indicators are selected and combined with the geographic probe analysis method qualitatively and quantitatively to explore the influencing factors of the spatial layout of hotels in Hainan Province.The research conclusions are as follows.(1)Current status of hotel distribution in Hainan Province: Number of hotels in Hainan Province takes up a smaller proportion as the hotel grade gets higher,showing a pyramidal hotel structure;due to the uneven distribution of economic and tourist space in each city and county in Hainan Province,there are large differences in hotel development between different cities and counties.In the north and south,the cities of Sanya and Haikou lead all types of hotels accounting for up to 58% of the number of hotels in Hainan Province,and the eastern region has more hotels of all types than the western and central regions,with a higher level of hotel development.(2)Spatial aggregation characteristics of hotels in Hainan Province: In general,hotels in Hainan Province are in a high aggregation mode from 2000 to 2020 in terms of time;in terms of different types of hotels,they are also in a high aggregation mode.The aggregation degree of various different types of hotels varies,mainly due to the differences(3)Spatial distribution trend of hotels in Hainan Province: From 2000 to 2020,the spatial distribution trend of hotels in cities and counties in Hainan province have the following distribution characteristics "core-graded" from the analysis of nuclear density.From the "double core" development form centered on Haikou City and Sanya City,it gradually evolves into the distribution pattern of two belt-like sub-core distribution belts formed by the main core of Haikou City and Sanya City,radiating the eastern cities and counties,and the belt-like sub-core distribution belt with Danzhou City in the west as the secondary core.The formation of this distribution state is mainly influenced by the development of each city.(4)Spatial and temporal evolution pattern of hotel layout in Hainan Province: During the study period,the standard deviation ellipse of hotels in Hainan Province has obvious directionality and always shows a "northeast-southwest" distribution pattern.On the whole,the standard deviation ellipse and the center of gravity of the ellipse shift to the southwest,indicating that the level of hotel development in the southern part of Hainan Province is improving faster,and gradually developing to the west.(5)Analysis of factors influencing the layout of hotels in Hainan Province: The geographic probe detection results show that the indicators of all types of hotels,the interaction detection results are greater than the single factor detection results,indicating that the spatial location of hotels in Hainan Province is the result of the combined impact of several influencing factors.The level of economic development and the degree of developed tourism have the strongest explanatory power for the overall hotels in Hainan.Based on the four latitudes of influencing factors to analyze the influence mechanism,the level of economic development,the degree of developed tourism,public service facilities and natural resources environment have driving force,guarantee force,driving force and attraction effect on the spatial layout of hotels in Hainan Province,respectively.Finally,this thesis puts forward four development suggestions based on the influence mechanism of hotel layout in Hainan Province: first,improve the level of regional economic development and drive the perfection of hotel grade structure;second,promote the high-quality development of tourism industry and guarantee the total market demand of hotels;third,strengthen the construction of public service facilities and promote the linkage development of regional hotels;fourth,give play to the advantages of natural resources in Hainan and promote the gravitational force of local characteristics of hotels. |
