摘　　要：组件式GIS是一个基于组件对象的地理信息系统开发平台。它以一组具有标准通信接口的、可跨语言应用的组件提供GIS功能。与传统的GIS相比,组件式GIS具有系统集成性好、开发语言多样、可扩展性强、易于进行二次开发等特点,已经成为地理信息系统的一个发展趋势。该文介绍了利用组件式GIS开发的广西农业区划应用系统,包括系统的关键实现技术、总体结构、系统的主要功能等,并给出了系统应用的实例。A component GIS is a component objects based platform for GIS applications development. It provides GIS functions with a group of components that have standard communication interfaces and can be used in multiple languages. Compared with traditional GIS, a component GIS has many advantages, for example, it is easy to integrate with other systems, can be conveniently embedded in multiple developing languages, has high extensibility, and can be easily used to develop a system. It has become a developing trend of GIS. The paper introduces the agroclimatic division system of Guangxi which is based on component GIS, presents the key implementation techniques, the architecture, the main functions of the system, and an example of system application is given.
