Abstract: The cellular automata model has the ability to simulate the process of 2 dimensional space evolutions in discrete time.Therefore,it is dynamic in time and space.This characteristic makes it very powerful in simulation of urban growth.This paper explains the parameters,transformation and rectification of SLEUTH model-one specific realized format of the cellular automata model,on which,the process of urban growth of Changsha city during 1996~2005 has been established.Moreover,the spatial morphology of Changsha in 2010 is separately predicted by the method of scenario simulation.The results show that it should be achievable when SLEUTH model is applied to simulate urban growth,and the accuracy of simulation results is acceptable.
