THE STUDY ON THE FRACTAL DIMENSION OF THE SPATIAL STRUCTURE OF THE CITY-TOWN SYSTEM BY RS TECHNOLOGY
以豫鲁皖交界地区为例，利用遥感影像计算城镇体系空间结构的分形维数为2.284，该指标可反映城镇分布的混乱程度。
Under the control of market-economy force, the spatial structure of the developed city-town system genrallly express such characteristics as non-scaling and self-similarity. This means the spatial structure of the developed city-town system is a fractal system. Taking the neighoring area of Henan, Shandong and Anhui provinces as a case study, the paper first gets raster images of the area from different heights (h), and then surprised-classifies these images and calculates the number of the pixels representing city-town type. Based on the recursive relation of the heights and the pixel numbers, the paper finds that the fractal dimension of the spatial structure of the developed city-town system is 2.284. The fractal dimension of the spatial structure of the city-town system is a valuable indicator showing the degree of the disorder of the distribution of the city and town.
