| 摘 要： | 本文利用面向对象的设计思想，对GIS中的二维图形符号进行了制图分类，抽象出构成二维图形符号的十种基于图元，并对这十种基于图元进行数据描述的数据结构进行了定义。基于这种分类的特殊图形符号灶，引入树存储已绘制的图形符号库，实现了对图形符号的浏览，调出，编辑及存入。

| Abstract: | This paper utilizes object - oriented paradigm to classify the two - dimensional graph and symbol in GIS, and abstracts 10 kinds of basic graph - elements that form all two - dimensional graphs and symbols. This paper also defines the data structure to describe these 10 kinds of basic graph - elements, designs the special graph classes on the basis of such categorizing and intrlduces treeview to store the graph and symbol data base to realize browsing, access, edition and storing. |

| Keywords: | object - oriented design graph and symbol data describing basic graph - element treeview node logic coordinate |
