Research on the fractal structure and its optimization of city recreation site system: A case study of Suzhou city
城市游憩场点系统结构分形及优化——以苏州市区为例

The hierarchical and spatial structures of recreation sites in Suzhou city are studied during the socioeconomic transformation in China using fractal theory and methods.The system of recreation sites are divided into three recreation subsystems in the ancient city,new city and outer city areas,which are the three levels of urban regional structure based on the 2008 general planning of Suzhou city.Then,using the Zipf fractal dimension,spatial correlation dimension and traffic length-radius dimension as index...
