元胞自动机（CA）模型在土地利用领域的研究综述

通过模型对区域土地利用/覆盖变化（LUCC）进行分析已经成为了当前全球的研究主要内容之一。元胞自动机（CA）模型是一种通过定义局部的简单的计算规则来模拟和表示整个系统中复杂现象的时空动态模型,其＂自下而上＂的研究思路,强大的复杂计算功能及高度动态,使得它在模拟空间复杂系统的时空动态演变方面具有很强的能力。CA模型通过与其他模型相结合,在综合考虑各种限制因素和转换规则的前提下,通过反复迭代综合空间分析与非空间分析,模拟土地利用变化情景,在国内外已经形成了较为成熟的研究模型。本文首先提出了CA模型在土地利用变化中应用的背景及其特点;然后,分析了CA模型的构成原理以及在国内外的应用进展与现状;最后,详细阐述了CA模型在土地利用变化中的发展趋势及今后研究工作中应注意的问题。

The Research Summary of Land use with the Model of Cellular Automata

The model of the regional land use /cover change（LUCC） has become main content of global research.Cellular automata（CA） model is a temporal and spatial dynamic model to simulate and represent complex phenomena in the entire system by definition of local simple calculation rules,its＂bottom up＂ research approach,strong functions of complexity computing and highly dynamic,make it has a strong ability in the evolution of the spatial and temporal dynamics of the simulated space complex systems.CA model by combining with other models in the premise of considering the various constraints and transformation rules through iterative comprehensive spatial analysis and non-spatial analysis,for the simulation of land-use change scenarios,both at home and abroad it has been a comparatively mature research model.In this paper we first give the background and characteristics of the CA model in the application of land-use change;then analyzing the composition principles of the CA model and application condition and progress at home and abroad;finally,we elaborated the trend of CA model in the land-use change and the problems we should pay attention to in future research.
