Abstract
Transportation network is the material conditions and prerequisites for forming the metropolitan area network system. It is also the main channel of material flow, energy flow and information flow which plays an important role in the socio-economic development of metropolitan area. Based on the urban-rural road network construction data of 1989, 1995, 2000, 2005 and 2010, this paper systematically reveals the spatial growth of urban-rural road network with the application of two major fractal dimensions using GIS spatial analysis methods. The node correlation dimension of urban-rural road network is high and the urban-rural node system growth is mature, which present a netted pattern. The urban-rural road network nodes approximately assume orthoscopic connection, thus the net accessibility is good. The spatial difference of urban-rural nodes correlation is obvious because there has positive correlation and space conjugate relation between the development level of space correlation of urban-rural nodes and area coverage or road network scale. From 1989 to 2010, the dendrite dimension of urban-rural road network of Wuhan metropolitan area maintained a stable growth tendency, showing a "discharge" stretch, significantly affected by urban and rural distribution and the natural environment, and the spatial distribution is relatively balanced.
