Study on Urban Growth Simulation Based on SLEUTH Model——Changsha City as an Example
|
Abstract:
The cellular automaton model has the ability to simulate the process of two-dimensional space evolution in discrete time.Therefore it is dynamic in time and space.The characteristic makes it greatly superior in simulating urban growth.The paper explained the parameters,transformation and rectification of the SLEUTH model-one specific realizid format of the cellular automation model,what'more,the author modified urban growth rule and parameter setting of this model in order to improve simulation accuracy.On the base of which,the process of urban growth of Changsha city between the year 1996 and 2005 is rebuilt.Moreover the spatial morphology of Changsha city in 2010 is separately predicted with the method of scenario simulation.The results showed that application of the SLEUTH model to simulation of urban growth is advisable.
