摘要
在传统的元胞自动机模型的基础上,结合GIS技术、城市扩展原理建立了研究区的GIS-CA城市扩展模型,模型综合运用灰色局势决策、层次分析法与CA模型确定元胞转变规则。在VS2010平台上,使用VB.NET语言,基于ArcGIS Engine组件开发了研究区城市扩展模拟系统,可模拟与预测研究区的城市扩展情况。使用研究区长春市的实际数据进行了验证,采用1993年、2005年遥感影像作为基础数据,应用GIS-CA城市扩展模型预测了研究区2005年城市用地情况,并进行了对比分析。实验结果显示,采用元胞自动机原理结合GIS技术研究城市扩展情况具有合理性、可行性。
GIS-CA urban extension model in the study area is established based on traditional cellular automata model, GIS technology, and urban extension principle. To determine the cellular transformation rules, grey situation decision, analytic hierarchy process, the CA model is integrated in the extension model. On VS2010 platform, using VB. NET language, based on Arc GIS Engine components urban expansion simulation system in the study area is developed,which can simulate and forecast urban expansion in the study area. Using the remote sensing images in 1993 and 2005 as basic data,the actual data in the study area of Changchun city as validation,the urban land in 2005 based on GIS-CA urban extension model is forecasted, and had been carried on contrast analysis. The experimental results show that it is reasonable and feasible to research urban expansion situation by using cellular automata theory.
