摘    要:结合城市空间的区域异质性特征,提出了顾及障碍空间距离和区域差异的CA城市扩展模型。以武汉市中心城区为例,在精确度量障碍空间的基础上,根据城市用地的不同形态和作用方式进行元胞空间的区域划分,构建动态的演化规则。实证表明,新模型能比较真实地模拟城市的扩展过程,结果可靠。

关 键 词:元胞自动机  城市扩展  障碍空间距离  区域差异

Abstract:Combining the characteristics of urban spatial heterogeneity,we put forward an urban CA model with considering the distance of obstacle space and regional disparity.Taking the central city of Wuhan as an example,the cellular space is divided into several regions according to different forms and function ways of urban land,and then establishes different conversion rules on the basis of accurate measurement of obstacle space.The case study reveals that the urban CA model with considering the distance of obsta...
Keywords:cellular automata  urban expansion  the distance of obstacle space  regional disparity
