| 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，本文介绍了该模型的具体参数、转换规则以及校正过程，基于GIS方法和遥感数据源，利用该模型重建了长沙市1996～2005年城市增长过程，并结合情景模拟方法预测了2010年长沙市城市空间形态。结果表明，运用SLEUTH模型模拟城市增长是可行的，并且其模拟精度是可以接受的。

| 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. |
