摘　　要：地图符号共享是空间信息共享的一个重要环节,然而当前空间信息共享往往侧重于空间数据的共享。针对这一现状,研究地图符号共享的核心基础——开放式地图符号统一模型,在地图符号绘制接口设计基础上,提出兼容矢量地图符号、影像地图符号、专题地图符号、栅格地图符号和拓展时间维的地图符号的统一接口模型,最后通过创建分别基于Visual Studio 2005(C#)和Silverlight 4.0的GIS符号库集成和互操作实验,验证上述接口模型具有跨语言的开放特性。Map symbol sharing is the key stage of spatial information sharing, which is always overlooKed among the development of sharing spatial information. To deal with this problem, open map symbol uniform model as the core of sharing map symbol is studied. Based on designing the interface of map symbol, a uniform interface model compatible with vector symbol, image symbol, theme symbol, raster symbol and time-extension symbol is proposed. Finally, an experiment of integrating and interoperating GIS symbol library based on Visual Studio 2005（C# ） and Silverlight 4.0 is made to prove that the uniform model is open enough to cross program language.
