| 摘 要： | 遥感异常提取是一种正在兴起、前景不可估量的遥感找矿方法。通过在青海省北祁连成矿带利用美国Landsat-7卫星ETM 数据进行遥感异常提取的应用研究,认为采用"去干扰-主成分分析-阈值处理技术"(DPT技术)为主要方法提取遥感异常效果较佳,并客观地评价了该技术的应用效果,同时也分析了遥感异常提取与应用中一些不足,指出了信息提取的局限性与遥感异常存在多解性等问题。

| Abstract: | Extraction of remote sensing anomaly is an advanced method for prospecting minerals. The method is just rising and its foreground cannot be predicted. From study of application of the American Landsat-7 ETM data in the northern Qilian metallogenic belt, this paper suggests that the DPT technique is the best in extraction of remote sensing anomalies. However, the technique also has some shortcomings and limitaions. Thus, additional explanation of the remote sensing anomalies are necessary. points out the limitation and various. |
