在对 Landsat7 ETM＋数据进行预处理的基础上，对多波段假彩色合成图像做滤波处理以增强区域构造特征来进行遥感构造解译；采用主成分分析和阈值分割法提取铁染、羟基蚀变信息；最后对解译的线性环形构造和提取遥感蚀变信息、航放异常和已知铀矿床(点)分布资料综合分析，圈定出3个找矿远景区。

The Enhanced Thematic Mapper image (ETM+)was used to study uranium metallogenic ele-ments in Qinglong area,Hebei Province.The image were first enhanced with color composition and image filtering technology,and linear and circular structures were identified by visual interpretation.The iron stained and hydroxy alteration information were extracted with Principal Component Analysis (PCA)and threshold segmentation.The relation of linear and circular structures,alteration information, airborne radioactive anomaly and uranium occurrences and deposit was comprehensively analyzed with GIS ,and three metallogenic prospective areas were finally predicted in Qinglong area.
