A fractal study on the urban system in Anhui Province

Based on fractal theory,the scale structure and spatial structure of the urban system of Anhui Province are investigated.From the perspective of scale structure,there is a relatively balanced population distribution in this area.Cities of intermediate rank are relatively developed while the monopoly of primate cities is relatively weak,and small cities are less developed.From the perspective of spatial structure,the aggregation dimension reflects that the urban system centering around Wuhu City shows a most compact spatial distribution,Bengbu City comes second while Hefei City is relatively loose.At the same time the grid dimension and the correlation dimension shows that the urban system of Anhui Province is mainly along the Yangtse River.That's to say,it develops in a line.As a result,the spatial interactions among cities are not strong and the network balance needs further improvement.In the end,based on the above analysis,some suggestions are put forward.
