摘　　要：在CorelDraw中绘制有些线状地图符号需要使用程序控制,无法直接调用CorelDraw的线状符号绘制功能。文中基于图元组合的思想,依据CorelDraw软件的特点,对常用地图中的线状符号进行分类、组织和存储,建立相应的线状地图符号库,设计专门的线状地图符号编辑器,实现对线状地图符号的统一编辑与管理,并且为不同类型的线状地图符号绘制设计相应的算法,最后利用CorelDraw提供的VBA二次开发环境实现文中所提出的方法,实验效果很好,可满足地图生产的需要。Drawing some linear cartographic symbols needs to be controled by program, because the plotting function of linear symbols can not be adopted directly from CorelDraw. According to the characteristics of CorelDraw, the study is based on the conception of graphical element composition. The commonly-used linear cartographic symbols are categorized, organized and stored, the relevant symbol base of linear cartographic symbols is established, the special editor is designed, the uniform editing and management is realized, and the algorithms are designed. Finally the method proposed is realized by taking advantage of secondary developmental environment of VBA in CorelDraw, and the result of the experiments proves to meet the needs of map production.
