哀牢山是重要的金矿成矿带。区内金矿床成因类型复杂,金的成矿作用和其地面波谱特征在整个三江地区都具诸多代表性。星载TM遥感数据不仅与地面反射,而且还与季相、光照条件、大气传输特性及传感器性能诸因素有关。在合理的大气物理假设前提下,经遥感方程的推导,证明区内遥感传感器在各波段接收的总反射亮度(R_(ij))与地物的反射亮度(W_(ij))呈线性相关。依据该线性相关关系确立的地空多波谱相关数学模式,建立了区内典型金矿床地面波谱与TM图像最佳波段的9个地空相关模型;在哀牢山地区典型金矿地面波谱数据的采集、研究基础上,建立了函盖区内已知金矿类型的双峰式、双谷式
Ailaoshan is an important gold mineralization belt. The genetic types of the gold deposits in the area are complex. The gold mineralization and its ground-based spectral features are representative of the whole Sanjiang area. Satellite TM remote sensing data not only reflect with the ground, but also with the quarter phase, light conditions, atmospheric transmission properties and sensor performance and other factors. Based on the reasonable assumption of atmospheric physics and the derivation of the remote sensing equation, it is proved that the total reflection brightness (R_ (ij)) received by remote sensing sensors in each region is linearly correlated with the reflection brightness (W_ (ij)) of the object. Based on the ground-atmosphere multi-spectral correlation mathematical model established by the linear correlation, nine ground-space correlation models of ground-wave spectrum and TM image of the typical gold deposits in the region are established. In the ground-based spectral data of typical gold deposits in Ailaoshan area Based on the collection and research, a double-peaked and a double-valley
