摘　　要：在分析岩性符号的结构特点和常规绘制方法的基础上,提出了基于图形元素和图像处理的岩性符号绘制方法。以《区域地质图图例》(标准号GB 958—1989—T)、《石油天然气地质编图规范及图式》(标准号SY-T 5615—2004)和《石油和天然气、煤田地震勘探图式、图例及用色标准》(标准号DZT 0077—1993)三个国家标准的扫描图例为基础,结合计算机图形图像与数据库技术,建立了标准的岩性符号库,解决了国内针对岩性符号的绘制和管理一直处于缺乏规范标准的散乱状态。On the basis of analyzing the structure features and the conventional drawing method of lithologic symbol, a mapping method of lithologic symbol is proposed based on the graphic elements and image processing. The standard lithologic symbol libraries is established, combined with computer graphics and database technology , and based on the three scanning illustrations in the national standards Geological Symbols Used For Regional Geo- logical Maps（ GB958--1989--T）, Drawing specification and pattern for oil and gas geology exploration（ SY-T 5615-2004） and Oil and natural gas coalfield seismic exploration schema illustrations and coloring standards （ DZT 0077-1993 ） , which solves the problem of the draw and management of lithologic symbol, which was always in messy state because of the lack of code standard.
