摘要
具备时空计算特征的元胞自动机模型 (CA)与 GIS集成将极大促进 GIS对地理过程的模拟能力。标准元胞自动机在元胞形态、邻居规则等方面的定义存在极大限制 ,制约了元胞自动机对真实世界的模拟和应用能力。论文充分研究了空间模型与元胞邻居描述的关系 ,发现元胞邻居在空间关系上存在拓扑邻接、空间邻近和复杂相离三种关系 ,传统思路的模型扩展很难完全解决CA的局限性 ,尤其是复杂相离关系。为此 。
The integrity of GIS and CA having the ability to calculate time and space will accelerate GIS's ability of simulating geographical process greatly.Standard CA has some restrictions in cellular shape and neighborhood and neighbor rules, which restrict the CA's ability to simulate real world and application. The paper discusses the relation between space model and cellular neighbor description, and we discover that cellular neighbor has three space relations including topological adjacency,space neighborhood and complicated separation. Therefore it is impossible to solve the CA's restrictions by extending CA model based on traditional thought. So we put forward a new CA extended model based on geographical object.
