论地理系统模拟基本模型

地理计算模型和地理信息系统(GIS)的集成是实验地理学研究急需解决的技术难点。地理系统丰富的内容、复杂的结构和功能的多样性,给人们分析、模拟地理系统带来了挑战。本文针对众多地理计算模型侧重表达、地理分析,多方法应用、众多模型无法筛选等现状,从计算地理学、地图学、地理信息科学等前沿需求出发,将地理系统模拟的基本模型归纳为在GIS平台支持下由点-多智能体(AB)、面-元胞自动机(CA)、流-系统动力学(SD)构成的地理系统模拟基本模型,并探讨了地理系统模拟基本模型的框架、结构与通讯,深入解析了各模型的原理、集成的关键技术与应用途径,为地理系统模型进一步发展及地理系统模拟平台研制与开发提供参考。

Multiagent Approach to Adsorption-Diffusion-Reaction Processes Modeling by the Method of Likelihood Cellular Automat

The discrete three-dimensional model of the adsorption-diffusion process was developed with three states using the comers of blocks within the framework of the theory of CA （cellular automata）. The construction of an asynchronous cellular automaton was used for the modeling, The implementation of the algorithm leads to a huge variety of dynamical regimes some of which are moving from the general chaos into a state of local and then global synchronization （within the framework of the model）.
