摘　　要：元胞自动机CA（Cellular Automata）是一种“自下而上”的动态模拟模型，具有模拟城市复杂系统时空演化过程的能力。CA和GIS的集成使二者在时空建模方面相互补充，能使CA模拟结果可视化显示。这里以郑州市为例，设计了城市CA模型，借助VB6．0和MapX5．0建立了一个与GIS无缝集成的2维CA模拟系统，并结合郑州市2005～2007年遥感影像图和土地利用图，对郑东新区进行了模拟，取得较好的效果。Cellular Automata （CA） is a bottom-to-top dynamical simulation modeling and possesses the capability to model space-time evolutionary process of the complicated city system. The model integrating CA with GIS can reinforce their spatial-temporal modeling each other, which makes result of CA simulation visible. Taken Zhengzhou as an example, a spatial-temporal dynamic model for urban growth by CA has been designed, and the simulation system for urban growth of integrating CA with GIS by VB 6.0 and MapX 5.0 has been developed. It was used to simulate urban growth in Zhengzhou East Area on the basis of Remote Sensing images and land use maps from 2005 to 2007, and got better result.
