Fractal Theories-based Research on Highway Transportation Networks Characteristics in Guangdong Province, China

摘要：

Based on fractal theories and supported by GIS technologies, radial dimensions (DL), ramification dimensions (Db) and correlation coefficients (R 2 ) of highway transportation networks are measured and calculated in the 21 municipalities of Guangdong and the province as a whole. The province is divided into four sub-areas (Pearl River Delta area, East Coast area, West Coast area and North Guangdong area) for analysis of fractal characteristics of highway transportation networks. The radial dimensions and ramification dimensions of highway transportation networks decay with distance increasing from Pearl River Delta area to the fringe areas, while the decaying degree is lower in Coastal area and higher in North Guangdong area. It is suggested by the results that the combination of radial dimensions and ramification dimensions enables the comprehensive analysis of spatial pattern characteristics of density ,structure ,connectivity and function of transportation networks.
