摘　　要：提出插件式 GIS 软件开发方案,把 GIS 软件开发分为宿主系统开发和功能插件开发两部分,每一部分都基于 COM 规范进行开发．通过插件连接器使得宿主系统具有标准的接口,功能插件通过安装可插入到宿主系统,实现功能模块的“即插即用”．论文介绍了插件式 GIS 实现方案、插件连接器开发、宿主系统标准接口的生成以及插件的开发,最后通过实例演示了具体的开发过程．This paper puts forward a “plug-in GIS development method”which divides the GIS software development into two parts： host development and plug-in development. Each part will be developed to comply with the COM specification. It will give the host a standard interface by using a plug-in connector, a plug-in can plug into the host by installing the plug-in. It realizes the “plug in and play ”by the two steps. This paper introduces four aspects., the scheme of plug-in GIS development, the plug-in development, the standard interface creation of host system and the development of plug-in. In the end, a case is demonstra- ted to explain the whole development process.
