哀牢山北段金矿田地面波谱反射率与ＴＭ图像亮度存有显著的线性相关关系。基于这种线性相关性，笔者用矿田内典型金矿床地面波谱的野外实测数据，经ＴＭ的相关分析，在哀牢山北段建立了９个地空相关模型。据这些相关模型，将ＴＭ图像反演成与金矿地面波谱有关的地空相关图像后，文章对该图像应用效果进行了讨论，认为其有较好的找矿靶区优选与定位的效果
There was a significant linear correlation between spectral reflectance and the TM image brightness in the gold area of Ailaoshan section. Based on this linear correlation, the author uses the field data from the ground-based spectral data of typical gold deposits in the orefield to establish nine ground-space correlation models in the northern segment of Ailao Mountain through the correlation analysis of TM. According to these related models, after the TM images are inverted into the ground-sky related images related to the gold ground surface spectroscopy, the article discusses the application effect of the images and finds that it has a better effect of selecting and locating target areas
