摘要
提出了一种面向对象的地理元胞自动机(GeoCA)。在与G IS结合的基础上,利用面向对象技术分析来设计GeoCA模拟系统,由VB+AO建立一个具有良好扩展性、用户可定制和友好界面的实验平台。通过采用MCE(多准则判断)来获取GeoCA模型的转换规则。以珠江三角洲的东莞作为研究区域,在GeoCA模拟的结果上,讨论了该地区的土地利用的变化趋势及所面临的问题。
Recently, there are growing studies on applying cellular automata （CA） techniques to the simulation of complex geographical phenomena, such as land use dynamics. There are problems on how to define transition rules and provide user-friendly interface for using cellular automata. An object-oriented CA is proposed, which has a number of advantages in simulating complex geographical phenomena. This architecture allows a better opportunity for model extension and model integration. In this paper, MCE （Muhicriteria Evaluation） techniques are mainly used to recover the transition rules of GeoCA, which take into account a number of spatial variables. A stochastic variable is embedded to address the uncertainties in urban simulation. A universal GeoCA model is designed based on the objected-oriented architecture with the capabilities of highly extendable, user-friendly through the Visual basic language and the ArcObject components of ARCGIS. This GeoCA model is tested in the simulation of fast land use changes in the Dongguan city, the Pearl River Delta of China. Plausible simulation results have been obtained by using this object-oriented simulation model.
