基于地理实体的城市元胞自动机模型研究

文章在分析传统元胞自动机模型模拟城市扩展存在问题的基础上，提出基于地理实体的城市元胞自动机模型——GeoObjectCA-Urban 模型。讨论了模型的三个构成要素:土地利用、交通和控制要素等元胞的表示方法和元胞 结构。着重分析了模型在构建过程中影响元胞状态的因子的简化和元胞状态的转化规则，给出了模型的实现方法，文章以义乌市为例进行实证研究，结果表明:模型具有良好的可操作性并具合理性。

Study on Urban Cellar Automata Model Based on Geo-objects

Cellular Automata has been used in simulation urban extension.But we cannot ensure the rationality of simulated results since it had adopted the rules of static,single and unrestricted variable.We established a new model named as GeoObjectCA-Urban which was based on urban geographical objects.We analyzed three factors of this model such as landuse,transport and control condition,and gave the expression methods and structure of the cellar.Especially,we emphasized on how to simplify the parameters and the tra...
