Using fractal theory and urban land-use maps for 1949, 1959, 1980, and 1996, this study is
devoted to analyzing the evolutionary features of urban form and land-use structure in …

Urban form takes on properties similar to random growing fractals and can be described in
terms of fractal geometry. However, a model of simple fractals is not effectual enough to …
