摘　　要：地理信息系统应用广泛 ,它们往往有不同的应用背景和建模需求。立足于地理信息系统的开放性和可重用性 ,运用基于组件的软件工程技术 ,提出了组件开放式地理信息系统结构 ,并详细分析了各组件的功能和它们之间的联系。采用组件开放式结构便于实现结构灵活 ,开放性强的应用系统。Geographic information system (GIS) is widely used in different fields that has different background and model. Based on the openness and reusability,the component-based open architecture of GIS is put forward. Function of the components and communication among them are discussed in detail. The architecture is proved to be better in openness and efficiency. Two examples of the architecture are also given.
