在栅格地理信息系统（GIS）中，建立了一个基于“灰单元”的约束元胞自动机（CA）模型，用于模拟不同类型的城市形态和发展。遥感和地理信息系统被用来提供信息的环境约束和增长中心的位置模拟。该模型能够考虑不同的标准，如城市形态，环境适宜性和土地消耗的可持续城市规划。七种不同类型的城市形态和发展，范围从紧凑的单中心，紧凑的多中心，紧凑的单中心环境，紧凑的多中心环境，分散，高度分散，非常高度分散的发展模拟使用该模型。该模型可以生成与真实的城市相近的分形结构的城市形态和发展。通过使用与可持续发展原则相关的不同成本指标对模拟模式进行评估。
A constrained cellular automata (CA) model based on ‘grey cells’ for the simulation of different types of urban forms and developments is developed within a raster GIS. Remote sensing and GIS are used to supply information on environmental constraints and locations of growth centers for the simulation. The model is able to consider different criteria, such as urban forms, environmental suitability, and land consumption for the planning of sustainable cities. Seven different types of urban forms and developments that range from compact–monocentric, compact–polycentric, compact–monocentric–environmental, compact–polycentric–environmental, dispersed, highly dispersed, to very highly dispersed developments were simulated by using the model. The model can generate urban forms and developments with fractal structures that are close to real cities. The simulated patterns were evaluated by using different cost indicators related to sustainable development principles.
