摘　　要：以全国大学生地质技能竞赛中综合地层柱状图绘制方法为例,探讨了传统Map GIS绘制综合地层柱状图和Map GIS投影法绘制综合地层柱状图的方法的不同,指出了Map GIS投影变换方法绘制综合地层柱状图的优点,能快速准确生成点、线文件,大大缩短绘图时间,避免数据输入时造成的偏差,提高绘图效率。竞赛的示范引领作用,促进了教师的教学方法改革与教学内容更新以及学生的思考探索。Taking the drawing methods of the synthetical stratum histogram in National Undergraduate Geological Skill Contest as an example,this paper discussed the differences between the traditional method of the Map GIS and the projection transformation method of the Map GIS.The advantages of the projection transformation method to draw the synthetical stratum histogram was pointed out,such as generating point and line files quickly and accurately,greatly reducing time,avoiding the deviation of data inputting,improving drawing efficiency and so on.The demonstration and leading role of the competition promoted the reform of the teaching methods,the update of the teaching contents,and the more thinking of the students.
