摘要
地质符号一般均有其特定的图形特征和表示意义，用以表达地质制图中所涉及的具体或抽象的地质对象。本文对地质符号（尤其是岩性符号）的有关计算机图形学方法进行了分析和比较。
Geological symbols generally have the specific graphical features and geological significances and can be used to present some concrete or abstract objects in geological drawing. This paper analyzes and compares the computer graphical methods representing geological symbols ( especially lithotype notations ) with each other, and presents a new comprehensive method-graphical element composition method and its classified code scheme for the computer graphical definition of geological symbols based on analyzing various geological symbols.
