摘　　要： 地理空间、地理梯度、地理流和空间关系是经典地理学进行地理过程分析常用的四个基本概念,元胞自动机(CA)作为复杂空间系统研究的重要工具,其对这些概念内涵的有效表达程度决定了其模拟地理过程的能力.在阐述了经典地理过程分析概念的基础上,分析了CA对这些概念内涵表达的有效性和局限性,提出了基于特征的CA概念模型,并进行了深圳市城市土地利用演化的实证研究.结果表明,基于特征的CA可以有效地表达经典地理过程分析概念,在城市土地利用规划中具有很大应用价值. Space, grade, flow and relation of geography are basic analytical conception of classical geographic process. As main tool of studying complex system, the ability of simulating geographic process of cellular automata (CA) depends on its descriptive ability to these conceptions. In the base of expounding these conceptions the paper analyzes the availability and restriction of CA in describing these conceptions; and attempts to bring the geographic characteristic concept including geometry and non-geometry attribute to model of CA; and makes a case study on land use evolvement of Shenzhen City. The study draws conclusions that the CA based on geographic characteristic is able to express effectively analytical conceptions of classical geographic process, and has great applied values in urban plan.
