摘要
细胞自动机(CA)固有的两个特征使之适于复杂的城市系统模拟研究。第一,它们本质上具有空间性;第二,利用非常简单的规则能产生复杂的行为,即局部的"不谐调"或个体的行为导致整体模式的有秩序性。通过选取五个典型事例回顾了20多年来城市CA发展历程,分析了该模型在当时的社会需要和技术水平条件下对城市研究所做的贡献及存在的问题,探讨了城市CA未来的发展趋势。
Cellular automata(CA) have two characteristics make them inherently attractive for application to complex urban systems simulation. The first is that they are substantially spatial; and the second is that they can generate very complex forms by means of very simple rules, namely the local 'uncoordinated' or individualistic actions lead to global patterns with order at higher level. In this paper, the author firstly reviews development of urban CA via selecting five representative instances, analyses their contributions under the temporal social requirements and technological levels and shortcomings, and at last discusses the trend of urban CA in the future.
