Abstract:

With the help of fractal methods of urban morphology based on iterative principles as well as fractal dimensions including correlation dimension，radius dimension and dilation dimension，this paper quantitatively analyzed the evolutional pattern of urban spatial structure of Xuzhou.Firstly,the study showed fractal dimensions could be used to reveal the spatial distribution and organizational structure quantitatively,while scaling behavior curve revealed the scale behavior of urban land use under different scales,and the application of the both could reveal the evolution law of urban spatial structure better.Secondly,the spatial distribution homogeneity of residential land,industrial land,and transportation land had been increasing while that of infrastructural land was poor.Thirdly,with the expansion of the city,an obvious ring structure of infrastructural land,residential land,industrial land from the center to periphery came into being and new commercial centers had been formed in periphery of city．Finally,compared with residential land and infrastructural land，the boundary of industrial land was complex and of poor stability.
