| 摘 要： | 本文分析了与金矿化相伴的蚀变矿物(铁氧化物、粘土矿物、碳酸盐矿物)的反射光谱吸收特征及金矿区上覆植被反射光谱对金矿化蚀变信息的干扰,同时介绍了利用植被指数法、比值-主成份变换法和植被掩模法对陆地卫星TM、JERS-1OPS等遥感图像进行处理,压抑植被反射光谱干扰信息和增强金矿化蚀变反射光谱信息的方法和效果。

| Abstract: | This paper analysed the feature of absorption spectrum of alteration mineral that relating to the gold mineralized alteration such as the ferraus, the clay and the carbonete, and the spectrum disturbance caused by vegetation covered the gold deposite area. Meanwhile, it introduced how to use the methods of the vegetation index, the radio-PAC and the vegetation masking to extract the information of gold mineralized alteration from Landsat TM and JERS-1 OPS data while the vegetation information was constrained. |
