摘　　要：以青海芒崖多金属矿化区为例,在ENVI软件的支持下,利用掩摸+主成分分析方法从TM多光谱遥感影像中提取与金属矿化有关的铁化、泥化蚀变遥感信息异常,并结合地质资料,区划成矿远景和圈定找矿靶区,取得了很好的实际应用效果。With the support of ENVI, This paper takes mangya polymetallic mineralization area in Qinghai province as an example, extracts the iron and argillic alteration information related with metal mineralization from TM multi-spectrum data by masking and PCA（principal component analysis） methods. Based on regionally geological information, ore prediction and target area outlining in the test region was carried out. A good application effect is obtained.
