Fractal cities study based on Remote Sensing images: —Take Huai'an, Jiangsu Province for example

摘要

Fractal theory promoted by the famous scientist Mandelbrot is widely used to research the fragment and irregular phenomena. Many urban geographers apply the fractal theory in the urban research. According to this, our researches utilize the fractal theory to Remote Sensing images to study the development of the city of Huai'an in Jiangsu Province. Firstly, we chooses the LandSat TM and ETM images in 1988 and 2000 as the main data sources. Then box-counting method is utilized to calculate the city's vector data and Peleg Double Blanket Method is used to get the fractal dimension of the city's image data. As we expected, the fractal dimension value become larger in 2000 compared with in 1988 which indicates that the city's structure needs to be changed exigently at that time. At last, the authors conclude the regularity between urbanization and fractal transformation and suggest some advices for the small city's development.
