摘　　要：本文在符号库设计的基础上,利用现有的符号库对地图要素进行符号化配置,探讨了符号智能配置过程中常用的绘制算法,研究了符号配置知识库,并针对符号配置中可能出现的冲突问题,进行分析和归纳,利用空间关系和Voronoi图对冲突进行研究,并对其提出了解决方案。In this paper, the present symbol base is used to symbolize the map features. The usual algorithms and knowledge database are analyzed during the symbolization of map features. The problems, which often occur in symbolizing the map, are studied in detail. The solutions to the problems are put forward by using the theories of spatial relation and Voronoi graph.
