摘　　要：为了提高绘制彩色平剖图的工作效率,利用Matlab对由Surfer软件中任意方向切割等值线得到的剖面数据进行批量处理,通过数据的平移、缩放和旋转换算等,形成平剖图;并沿剖面找出场值的零值点位置,将正值段用暖色线绘出,负值段用冷色线绘出,使图面上能较方便地显示出正值区和负值区,从而实现彩色平剖图的自动绘制。最后将处理结果保存为Surfer软件中*.bln类型文件格式,可在Surfer中直接调用并形成基面图,实现彩色平剖图与等值线网图或其它地理底图的叠合,为地质解译提供便利。To improve the efficiency of drawing color plan-profile map,this paper proposed to complete the plan-profile map by using Matlab software to batch process profile data obtained from cutting contour maps on arbitrary direction in Surfer software, through data translation,scaling and rotation conversion etc.And the automatic drawing of color plan-profile map is achieved by finding out the position of zero-value along profile,making the positive segment drawn with the warm color, while the negative segment drawn with cool color, so that positive and negative area can be more obvious,Finally,by saving the results as *.bln type file format in Surfer software,which can be called directly in Surfer to form the base surface map,the purpose of superimposing color planprofile maps on contour maps or other geographic maps are achieved,which will facilitate the geological interpretation.
