Abstract:

The author finds that the character of self-similarity is very clear in Hangzhou when he studies the evolution of urban morphology and structure of urban land use using the theory of fractals. By dint of the box counting method, several maps of urban land use of different years are utilized to extract the basic data, and then the fractal dimensions of urban morphology and seven kinds of land are calculated. It is not difficult to find that most of the standard error σ are less than the criterion δc = 0.04, which was put forward by Benguigui et al. The author finds that the status of fractals of urban morphology and land use structure tend to be better with the elapse of time, which testify the viewpoint of foreign scholars about the evolving city fractals. Another important findings of the paper is that the fractal dimension of every land use is less than that of the total urban morphology, which is only a theoretical deduction before. From the viewpoint of spatial-temporal change, the fractal dimension of Hangzhou's urban morphology tends to be increasing, and in 1996 it is near D = 1.71, a mean value of fractal dimension summarized by Batty et al. As far as different urban land use of Hangzhou is concerned, the fractal dimensions of residential, industrial and external traffic land tended to be increasing from 1980 to 1996, while the fractal dimensions of education and virescence land tended to be decreasing during the same period.
