在豫西熊耳山地区地物反射波谱特征研究的基础上，提出了一种从ＴＭ数据中自动提取金矿遥感异常信息（近矿围岩蚀变信息及植被毒化信息）的新方法。该方法消除了在围岩蚀变信息或植被毒化信息提取过程中，由于植被覆盖程度的差异对矿化信息提取的影响，因而适于植被覆盖程度不同的任何地区，在豫西熊耳山地区试验应用中取得了良好的金矿找矿效果
Based on the study of the characteristics of the surface reflection spectra in the Xiongershan area in western Henan, a new method for automatically extracting gold mine remote sensing anomaly information (alteration information and vegetation poisoning information of nearby ore) from TM data was proposed. The method eliminates the influence on the extraction of mineralization information due to the difference of vegetation coverage in the process of extraction of vegetation alteration information or vegetation alteration information and is therefore suitable for any area with different vegetation coverage. Application made good gold prospecting results
