摘　　要：本文介绍了面向虚拟地理环境的基于概念模型的图形化地理建模方法,利用面向对象方法设计了可扩展的图形化地理建模的体系架构,并详细介绍了实现图形化建模的关键技术。应用成果表明:该体系架构具有高度的可扩展性和适应性,支持基于模型组件构建复合地理分析模型,有助于对地理现象、地理机理和地理过程准确认知。Based on the conceptive model, a method of vision geographic modeling relevant to the virtual geographic environment was introduced. Utilized Object Oriented Programming, an extensible framework of vision geographic modeling was constructed. Moreover, the key techniques which were used to perform the visual geographic modeling were displayed as well. All these applications show that the framework is both extensible and adaptable, which not only supports the compound model constructed by the model components, but also benefits the realization of the geographic phenomenon, mechanisms and processes correctly.
