摘　　要：以 ETM图像数据为信息源 ,在西昆仑塔什库尔干地区进行了遥感找矿异常提取的方法研究 ,根据矿化蚀变的遥感影像特征 ,进行了基于光谱特征和纹理特征的矿化蚀变信息提取和分类方法的试验 ,选定了区内的最佳遥感异常圈定方法。针对区内与铜矿有关的主要蚀变类型分类进行了提取 ,分别赋色后叠加形成了遥感矿化蚀变异常图 ,并结合区域成矿地质特征进行了成矿远景区的划分。Using ETM space image data as the information source, we did some information extraction study on remote sensing mineralizing anomaly in Tashkuergan area of West Kunlun mountain. We tested some mineralizing abnormal information extraction and classification method based on spectral signature and texture characteristics, accessed the best remote sensing mineralizing anomaly Extraction program. We extract the three types of mineralizing alteration related with copper in studing aera, then different color given and superimposed tegather as a remote sensing map of mineralizing alteration. Based on the procession and the map and the regional mineralizing geological conditions, we recognize four prospecting area in this region. At last, we sum up a set of working process on extraction of remote sensing mineralizing alteration anornaly.
