Abstract:
Fractal has become an important method and perspective for researchers to study city structures and other fields. From the perspective of system theory, fractal theory is the best choice to study spatial structures of regional scenic area systems as well. Its of some theoretical significance and practical value to reveal the fractal features of spatial structures of scenic area systems and their control rules. Nowadays, some researches on fractals of spatial structures of scenic area systems have been conducted, however, making a comprehensive view of the existing researches is as follows. (1) The researchers framed the spatial scales within a prefecture level city or an urban area, and provincial areas were the commonly used dimensional types in studying the industrial layout and planning. Yet there is no research on spatial fractals of scenic area systems in provincial areas. (2) The researchers only studied the spatial fractal features of scenic area systems at a certain time point without the contrastive analysis of time series to show the evolution characteristics. (3) In measuring aggregation dimensions and spatial correlation dimensions, the researchers just gave the analysis of spatial distance, instead of that of time distance, while tourists were not only concerned about the spatialdistance between scenic areas but also the timedistance. By using the aggregation fractal model and dividing the last decade into four temporal phases, this article investigated the characteristics of evolution of aggregation fractal of 4A and 5A scenic area system in Northern Jiangsu, Middle Jiangsu, Southern Jiangsu and the whole Jiangsu province based on synthesized spacedistance and synthesized timedistance. The research results showed that (1) the four scenic area systems all appeared the aggregating distribution, but the aggregation level in Northern Jiangsu and Middle Jiangsu was higher than that in Southern Jiangsu and the whole province; (2) the four scenic area systems were in welldistributed pattern evolution, with fastest evolution in the middle, slowest in the south from the perspective of spacedistance and with fastest evolution in the north, slowest in the south from the perspective of timedistance; (3) the spatial structure of each scenic area system based on timedistance was closer to the welldistributed pattern than that based on spacedistance; (4) the optimization level of transportation network between the scenic areas in Northern Jiangsu and Middle Jiangsu was lower than that in Southern Jiangsu and the whole province; (5) the evolution speed of each scenic area system based on timedistance was faster than that based on spatialdistance. The research conclusion can provide some reference for the spatial layout of scenic area systems in Jiangsu Province
