| 摘 要： | 岩石的吸收光谱主要是由杂质、包体、蚀变及替代成分产生的，每种岩石都难以形成象它的组成成分那样具有可分辨的很清晰的光谱特征；不同类型的岩石放射性元素的含量和分布特征是不同的，岩石放射性信息是岩性识别研究的重要判据。遥感与航空放射性信息的集成．既能提取光谱图像中的光语信息和空间纹理信息。又可利用航空放射性信息常常具有的甚至是诊断性的岩性识别能谱标志。能明显提高识别岩性的精度，更重要的是能谱不受值被的影响，有利于识别植被覆盖区的岩性。因此，这可能是遥感岩性识别研究的发展趋势之一。

| Abstract: | The absorption spectrums of rocks are caused by their impurity, inclusions, alteration or substitution components, thus no specific unique spectrum can be used for discriminating each type of rocks as their compositions do. As the compositions and distribution features of radioactive elements in various types of rocks are different, the radioactive information of rocks are very important for the study on rock identification. The integration technique of remote sensing and airborne radioactive information can retrieve not only the information of spectrum and space lamination from the spectral images, but also the airborne radioactive information which could be diagnostic for rock identification. This will improve the accuracy for identifying various types of rocks, especially for its application in the rock identification in the vegetation area, as the spectrometry will not be affected by the vegetation. Therefore, it is believed that the spectrum-spectrometry integration technique is the right direction for the study on rock identification by remote sensing. |
