Abstract:

As the important research object of tourism spatial structure，the research of spatial structure of scenic spots has become one of the hottest topics in the study of tourism geography The research of spatial structure of scenic spots is helpful to the optimization of tourism spatial structure，and to promoting regional tourism development Spatial difference of scenic spots often shows different spatial function form in different period and stages，and spatial polarization and spatial diffusion are the basic forms of interaction of scenic spots According to the spatial action forms and rules of scenic spots， in different development stages，taking corresponding tourism development policy could scientifically and reasonably guide and plan tourism spatial structure，and play the integration effect of regional scenic spots during the process of tourism development Wuhan Metropolitan Area has rich tourism resources and high tourism development level， but the spatial differences of regional tourism development level is large and regional tourism development is not balanced Applying Lorenz Curve， centralization index and spatial autocorrelation method， the year 2001，2006 and 2010 as the researching time section， combining GeoDA and ArcGIS spatial analysis tools，  the spatialtemporal differences of scenic spots in Wuhan Metropolitan Area were analyzed The research shows as follows Firstly， scenic spots in Wuhan Metropolitan Area had significant spatial difference Scenic spots were mainly distributed in Wuhan， Xianning Huanggang，etc， and the spatial centralization level assumed the decreasing trend Secondly， spatial autocorrelation of scenic spots was enhancing trend in general， and the dualization spatial distribution pattern showed continuously strengthened Thirdly， the hot spot area of scenic spots showed some spacetime inheritance， had obvious geographical neighbors effect Hot spot area of scenic spots were Wuhan， Xiaogan， Ezhou， etc， with the trend of the east moving Tianmen， Xiantao and Qianjiang had always been development cold spot area of scenic spots Finally， population distribution， economic development level， tourist traffic were regarded as the main influencing factors of space difference of scenic spots in Wuhan Metropolitan AreaApplying GeoDA and ArcGIS spatial analysis tools， this paper revealed the spatiotemporal difference and similarity  of scenic spots in Wuhan Metropolitan Area， and showed the interaction and its evolution， to provide a theoretical basis for optimizing tourism spatial structure of Wuhan Metropolitan Area， coordinating the regional tourism development and making scientific tourism development policy
