中文摘要：

采用姑婆山地区ETM＋遥感影像数据,运用ENVI进行图像预处理、MapGIS提取花岗岩体线性构造信息,制作出线性构造等密度图及线性构造走向-密度玫瑰花图。结果表明：姑婆山在NE和NW两个方位区域的线性构造为优势方向线性构造;姑婆山岩体的线性构造密度呈双环带分布,一是以里松单元为低值中心向外递增的环带状分布,二是以新路单元为高值中心向外递减的环带状分布。不同的密度区与姑婆山花岗岩体单元的划分存在对应关系。

英文摘要：

ENVI and MapGIS software are used in linear structure density diagram and linear structure strike-density rose diagram with ETM＋ imagery in Guposhan area,Guangxi.The results show that in the NE and NW direction there are advantage direction linear structures.The linear structure density in Guposhan shows double-ring shape with Lisong unit as low value zone increasing outward and Xinlu unit as high value center decreasing outward.So there is corresponding relation between different density area and granite rock unit division in Guposhan area.
