引入数据场和地图代数思想,对传统元胞自动机模型进行拓展,提出了元胞场和元胞势的概念,建立了一种新的转化规则,构建了基于地图代数和数据场的元胞自动机模型。实证结果表明,与传统克拉克城市扩展模型相比,该模型能更好地体现城市的扩展过程。
By introducing the theories of data field and map algebra,the traditional cellular automata is extended and improved.We put forward the concepts of cellular field and cellular potential in accordance with the definition of potential function in data field,and establishe an original conversion rule.Then,we construct cellular automata based on map algebra and data field.Compared with the results of this new model and the traditional Clark urban growth model,the poposed model simulates urban development better.
