摘要
元胞自动机具有模拟二维空间演化过程的能力,并且在时间上也是离散的,因此具有很强的时空动态性,它的这种特性使其模拟城市增长具有明显的优势。SLEUTH模型是元胞自动机模型的一种具体实现形式,通过介绍该模型的增长参数、增长规则以及校正过程,提出了可提高模拟精度的增长参数与增长规则改进方法。最后基于GIS方法和遥感数据源,将该模型应用于长沙市,重建了1996~2005年长沙市历史城市增长过程,预测了2010年长沙市城市增长情景,证明了SLEUTH模型模拟城市增长的可行性。
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.
