A Study On The Spatial Structural Evolution In Forest Park Based On Aggregation And Fractal

With the rapid development of forest tourism, forest tourism plays a more important role in tourism and the forestry industry. Forest tourism is becoming more and more competitive, Forest Park as the main carrier of forest tourism, its spatial structure conditions directly affect the development of forest tourism. "Hunan province twelfth five-year plan for national economic and social development" focus to build a strong province of tourism in human province, more requirements of Hunan tourism resources of the rationality and validity of the space layout. Therefore, how to optimize the spatial structure of forest tourism, the forest tourism scenic area (point) between the more reasonable layouts, spatial relationship more harmonious, has become a problem to be solved, also become the forest tourism research field is an important research topic.Now many experts and scholars studied the tourism spatial structure of Hunan province, but the application of fractal theory to the forest park space structure research is less. This article use 54 national forest park in Hunan province as the research object(by the end of 2015), using the fractal theory of fractal, the grid fractal and spatial correlation fractal model, studied the 54 national forest park in Hunan province, through calculation and analysis of the collected data, it is concluded that Hunan province national forest park of the spatial structure characteristics of the system. Main conclusions are as follows:(1)Forest park of Hunan province 54 national forest park in the system of spatial attribute data calculation and analysis, show that national forest park of Hunan province had obvious fractal spatial structure characteristics of the system, and the spatial structure is optimized by trend;(2)Through aggregation dimension calculation and analysis, the system of national forest park of Hunan province in the clustering effect is strong, and the Zhangjiajie national forest park and aggregation strongest Yang Ming mountain national forest park, in the process of the future development of forest tourism in Hunan province, can become the core of forest tourism.(3)Through grid dimension calculation and analysis, the national forest park of Hunan province system grid d numerical slightly less than 1.5, the national forest park in the province of Hunan province within the scope of distribution more uniform, and the national forest park mainly from city suburb area or range, and high forest coverage rate and forest resources in regional scale, national forest park system in the spatial structure on the distribution of Hunan province is on the condition of small clusters as well.(4)Through the calculation of correlation dimension and analysis shows that national forest park of Hunan province system’s correlation dimension ratio equal to 1, shows that national forest park in the system each national forest park of Hunan province direct spatial correlation is very good, the distribution of the national forest park in a relatively smooth curve, the spatial distribution is very beneficial to the future development of forest tourism in Hunan province, at the same time, is beneficial to the future of Hunan province special tourism circuit design and the integration of forest tourism products.Combined with the results of the study put forward some Suggestions:make "One area two hearts" of forest tourism destination; Enhance the operational efficiency of the provincial traffic network system, The development of forest, raise tourist products; To execute region linkage, make with characteristic of regional combination of tourism products. For healthy sustainable development of forest tourism industry in Hunan province.
