The Suzhou urban expansion as the research object, used the 1987,2000,2005 and2009 Landsat TM / ETM+ multi-objective remote sensing images to acquire the Suzhou urban landscape map, from the urban expansion speed, urban expansion strength, urban expansion elasticity coefficient, and the urban expansion direction to analyze the urban expansion dynamic changes, and then used the fractal model to calculate the Suzhou construction land fractal dimension and stability indexes in 1987-2009, and explored the relationship between the urban construction complexity and stability and the fractal dimension. The results show that, with the urbanization process accelerated, the construction land area in Suzhou City continued to increase, the urban expansion strength further enhanced, the urban expansion speed further accelerated, the city development direction mainly toward the north and south, southeast and northwest. The 1987-2009 urban construction land fractal dimension showed increasing -- reducing -- increasing trend, the urban construction land shape become more and more irregular, the urban construction land complexity increased, the urban construction land plaque stability decreased gradually.
