| 摘 要： | 符号库引擎是GIS平台与符号库进行交互的中间件，符号库引擎的框架以及接口的设计好坏决定着GIS系统符号编辑功能的强弱，本文主要讨论了开发一个与GIS平台无关的符号库引擎应考虑的问题，以及基于软件重用的思想设计了6个功能模块具体探讨了符号库引擎的设计与实现。

| Abstract: | The engine of symbolic library is the mid-ware between symbolic library and GIS platform. How to devise the framework and interface of the engine will have a lot of effect on the edit function in the GIS platform. This paper mainly discussed how to develop an engine of symbolic library, which is not combined with certain GIS software, and designed six function modules based on software reusing, as well as discussed design and implementation for the engine of symbolic library. |

| Keywords: | the engine of symbolic library independence of GIS platform software reuse |
