Fractal researches on the spatial structure of the urban system in Sheyang Economic Zone

摘要

This paper used three kinds of fractal dimensions to characterize spatial structure of the urban system in Shenyang Economic Zone, namely aggregation dimension, spatial correlation dimension, and box-counting dimension. It was found that the spatial structure of the Shenyang Economic Zone urban system has obvious fractal properties. In analysing the results of our research the following conclusions emerged: The space distribution of the Shenyang Economic Zone urban system is centripetal gathered around the central city of Shenyang, the accessibility of the transport network between cities is good, and the spatial shape is more compact than other urban systems of Liaoning Province. The authors believe that the structure of the Shenyang Economic Zone urban system is more effective than the structure of Liaoning Province urban system, and put forward rationalization proposals to optimize the urban system of the Shenyang Economic Zone.
