摘　　要：钻孔柱状图是GIS(geographic information system)中常用的辅助工具,绘制柱状图需要绘制岩性花纹,并且岩性花纹与岩性名称一一对应。主要针对钻孔柱状图的具体特点,提出一种新的矢量花纹填充方法,即将花纹以线的形式分解到填充区域中,然后根据线的参数决定该段线是否绘制。同时针对地层岩性复杂性的特点,研究了复合矢量花纹填充算法,将比例因子考虑到算法中,实现多个花纹填充问题。实验快速通过了紫金西北段矿区钻孔柱状图的绘制,充分证明了算法的高效性。Drilling histogram is commonly used in GIS tools, and lithologic pattern is needded when drawing the histogram. Lithologic pattern is one to one correspondence with the lithologic name. A new method of vector pattern fill is mainly proposed aims at the characteristics of drilling histogram. The pattern is decomposed into several type of lines, then drawing the line according to the parameters of the line. At the same time, given to the complexity of layer, it also discusses a composite vector pattern filling algorithm which considers the scaling factor relationship between patterns. This algorithm can fill several patterns into one area. The experimental result about the histogram of zijin northwest mine, is fully proved the high efficiency of the algorithms.
