摘　　要：本文以.NET为开发平台,以C#为开发语言。首先分析了开发GIS软件中存在的问题,然后介绍了一种新的二次开发方式——插件式GIS应用框架。在此基础上,设计了MYGIS框架。设计过程主要包括框架插件引擎、框架宿主程序、框架插件三大部分。利用插件式应用框架进行二次开发具有灵活、扩充性好,功能模块之间聚合性高、耦合性低等特点。本文主要探讨以下问题①宿主程序如何识别插件对象。②插件的UI对象如何被初始化。③插件对象如何产生它们的UI对象。④插件的UI对象被触发时如何与插件产生互动。The thesis＇ development platform is.NET and development language is C#.The thesis analyzes firstly the existent problems in developing GIS software,and then introduces a new secondary development scheme——Pluggable GIS Application Framework.On the basis of the introduction,MYGIS framework is to be designed.The design process includes three main parts,Plug-in Engine,Host Application and Plug-in.Secondary development that use Pluggable Application Framework,which has the characteristics of flexibility,convenience,and extendibility.The problems settled in this thesis are as follows：①How the Host Application to distinguish the Plug-in.②How initialize the User Interface of the Plug-in.③How the Plug-in to produce their User Interface.④How the User Interface of Plug-in to interact with Plug-in when it is been triggered.
