摘　　要：分析现有地图符号构建方法的结构特点及优缺点。从地图符号学研究符号语义表达和图形结构出发,充分利用SVG的描述能力,将地图符号的构建设计为两个部分:SVG结构化描述的语义图元库与符号节点树,提出了基于SVG的地图符号描述模型。该方法丰富符号构建方式,且能够很好地与SVG映射,便于符号共享应用。The structural characteristics, the advantages and disadvantages of the existing map symbol construction methods were analyzed. In terms of the map semantic expression and graphic structure, the description advantages of SVG were fully taken, the construction of map symbol was designed of two parts： the description of the map symbol semantic primitives library based on SVG and symbol constructed of semantic primitives by node tree. The description model of map symbol based on SVG was proposed, it not only enrich the method of creating map sym- bol, but also construct the well mapping with SVG. The sharing of symbols is more facilitated.
