三亚市旅游休闲业态时空演变特征及其形成机制分析.

Taking Sanya City as a case, based on POI data of six types of tourism and leisure forms, comprehensive use of spatial analysis technologies such as the nearest distance index, nuclear density estimation, multispatial clustering and geographical detectors to deeply measure and explore the spatial and temporal evolution characteristics of Sanya tourism and leisure forms and their formation mechanism. The results show: (1)The overall number and characteristic spatial scale rise sharply, and the distribution pattern is "polar core-axis-surface domain"; mainly gather Sanya bay resort and spread the surrounding coastal area, and the agglomeration degree increases with the increase of spatial scale. (2) All kinds of tourism and leisure formats space agglomeration characteristics, including shopping, accommodation, catering industry and overall agglomeration characteristics have highly consistent, all kinds of formats agglomeration distribution characteristics are significantly different and scale dependence is obvious, the tourist attractions formats concentration degree with increasing time distance, the rest of the formats all increase after decrease. (3) The formation of Sanya tourism and leisure form space pattern is determined by the policy guidance of urban development orientation, that is, in the tourism and leisure demand upgrading and upgrading of urban development, from the economic level, population characteristics, traffic conditions and resource endowment affect the evolution of tourism and leisure business space pattern.
