摘　　要：针对实测地质剖面图绘制费时费力的问题,提出一种按照复数运算规则计算实测地质剖面要素的投影绘图方法。该方法根据地质方位与复数辐角定义的相似,使地质方向东西、南北坐标轴分别与复数的虚、实轴重叠,按照复数运算规则计算导线位置、地形起伏、岩层线、产状等各实测地质剖面要素的空间位置,并通过Generic Mapping Tools(GMT)软件对计算结果进行投影绘图。实验结果表明:该计算机绘图方法绘制效率至少是手工绘制效率的几十倍,绘图时间最多是手工绘图时间4%左右;图件清洁干净,易于识别,比手绘图件更精准。该绘图方法不需要对语言和软件的精确掌握,更易于在广大地质工作者中得到推广和使用。Aiming at the problem that it is a time-consuming and laborious work to draw the geological section,a section drawing method which calculates all the geological factors according to the rules of complex calculation was implemented. This method enabled the east-west with the complex image axes and south-north axes with the complex real axes to separately overlap based on the similarity between the geological direction and the complex angle; then calculated the spacial locations of the distribution of leading line,topografic relief,stratum line,stratum attitude,etc.; at last the Generic Mapping Tools（ GMT） was used to achieve the final projection mapping. The experimental results shows that,the efficiency of the computer section drawing method is at least dozen times as quick as the hand drawing section,and the time cost is at most 4% or so of the hand drawing section; the maps are clean and easy to be identified,and more accurate than hand-drawn pictures. This computer drawing method doesn＇t demand to master the language and software,so it＇s easy to be popularized and applied by the geolocal persons.
