摘　　要：以图形替换图形为原则,定义了基于符号描述的图形重写系统,根据符号系统的文法复杂度和应用的需求对图形重写系统进行了分类,重点分析了上下文无关的图形重写系统常见结构、处理方法以及与IFS和L系统关系.结果表明,图形重写系统比L系统和IFS更简单,造型能力更强,构图过程更直观.In line with the principle of replacing graphic by graphic, the Graphic Rewriting System based on the description of symbols is defined here. According to the complexity of the symbol system and its applied requirements, the Graphic Rewriting Systems are classified. Our emphasis is laid on analyzing context- free graphic rewriting system, including its usual structures, processing methods and its relation with L-System and IFS. The results show that the Graphic Rewriting System is simpler than L-System and IFS. Furthermore,its modeling ability is stronger,and the modeling process is more direct to our sight.
