摘　　要：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。Based on the studying of reflecting spectrum feature of some material in Xiongershan in West Henan.In this paper, a new method for extracting the anomalous information (hydro-thermal alteration information and poisonlized plant information) of remote sensing of gold deposite automaticly from Landsat TM data is developed.As there are no influence caused by vegetation in extracting the imformation that talk above, this method can be applied in any regions being covered with different degree of plant. The great successes have been achived in seeking gold deposite in Xiongershan in West Henan.
