The scaling exponent and the first kind of fractal dimension values (boundary dimension 1) were estimated and provided by Dr. Xinsheng Wang, who assumed that the dimension of urban form is (see [38]). **The second kind of fractal dimension values (boundary dimension 2) was estimated through the scaling exponent values by this paper’s author, who assumed that the dimension of urban form is
