Type Division,Pattern Evolution and Influencing Factors of Tourism Land in Hainan Island
The compound characteristic of tourism land leads to the variability of the functional structure of tourism land.The functional structure and spatial structure of tourism land have changed obviously under the policy drive.This paper uses ENVI,ArcGIS and other software to analyze the satellite remote sensing image data of Hainan Island at 4 stages:the early stage of establishment as a province,the middle stage of construction as an ecological province,the middle stage of construction as an international tourism island and the early stage of construction as a free trade port.Based on the tourism land function,it divides tourism land into four types,namely,natural tourism land,infrastructure tourism land,cultural facility tourism land and ecological landscape tourism land,and analyzes the classification and distribution characteristics of tourism land use in Hainan Island.It analyzes the functional structure,spatial pattern and evolution characteristics of tourism land in Hainan Island using the methods of the kernel density analysis,the Lorentz curve and the nearest neighbor analysis.It uses Pearson correlation model to explore the driving mechanism of tourism land spatial pattern in terms of policy factor,economic factor,demographic factor,infrastructure factor,environmental factor.The results show that:1)The proportion of natural tourism land is high,and the development of ecological landscape tourism land is rapid.2)The gravity center of tourism land lies in the southeast corner,and obviously moves toward the north and west of Hainan Island,and different type of tourism land has its own characteristics.3)The natural tourism land and ecological landscape tourism land are both concentrated in the central and southern part of Hainan Island,the cultural facility tourism land is concentrated in Haikou City and Sanya City,and the infrastructure tourism land is scattered.4)The increase of tourism land is scattered,mainly concentrated in Haikou and Sanya.5)Policy factors are important driving forces for the expansion and spatial layout of ecological landscape tourism land,infrastructure tourism land and cultural facilities tourism land in Hainan Island.Economic factors have a strong driving effect on tourism land.Population factors have an important impact on the land used for cultural facility tourism land and infrastructure tourism land.On this basis,it puts forward some countermeasures and suggestions for the optimization of tourism land pattern and regional sustainable development in Hainan from the aspects of diversification of tourism land types,optimization of social ecosystem network of tourism land,driving effect of policy factors,cultivation of local embeddedness,rural revitalization and regional development.
