摘　　要：传统的GIS开发方式多采用结构化的设计思想,对于不同GIS信息系统的建设,需要重复去设计、开发相关模块,开发效率较低。文中将组件重用思想应用到GIS开发实践中,总结基于组件的软件重用技术,探讨GIS开发中常见可重用组件接口的设计思路,包括:主界面接口设计、空间数据库互操作接口设计和查询接口设计。通过开发实践证明,基于组件重用思想的GIS开发具有良好的开放性,可以高效、快速地开发出更稳定的应用系统,显著降低开发成本。The traditional GIS application is mostly developed by adopting structured design thought which needs repetition of the design, and develops related module with the low efficiency. So the paper introduced the reusable components to the GIS application development practice, summed up the componentbased software reuse technique, discussed the common interface design thoughts of GIS development, including, the main interface design, spatial database interoperation interface design and query interface design. Practice has proved that through the development, based on reusable components thoughts of GIS development has a good openness, can be highly efficient and rapid development of a more stable system, a significant reduction in development costs.
