Abstract

By interpreting remote sensing images of Nanchang city in seven phases from 1976 to 2004, we get the profiles of the main build-up area of Nanchang city in these phases. And then the compact ratio, Boyce-Clark shape index and fractal dimension of each profile were calculated. Based on these, the conclusion is drawn that the spatial expansion of the main build-up area of Nanchang city was turning discrete before 2000 and then became more and more compact. Besides, the Nanchang City didn't have the fractal character as a whole in the past three decades, but it showed up when it refers to certain areas, and the scale range varied as the evolvement of the spatial expansion. On the other hand, the value of the fractal dimension was further and further away from the standard value before 2000 and then became close to that, which appeared the similar trend with the change of the city compactness. It's indicated that the city is more and more self-organized.
