本文论述了广东鼎湖钼矿区生物地球化学异常特征和植物波谱特征，并对该区的ＴＭ图像进行了较深入的分析与应用处理。研究结果表明，钼矿区的植物波谱反射率与ＴＭ灰度值均比对照区的高，经Ｋ－Ｌ变换后的ＴＭ假彩色合成影像上，钼矿区呈现的形状、色调均与对照区有明显区别，研究区ＴＭ影像特征主要受植物叶中的铝含量及叶绿素含量的影响。本研究结果为在植被覆盖区用生物地球化学遥感探矿提供了理论依据。
This paper discusses the biogeochemical anomaly characteristics and plant spectral characteristics of the Dinghu molybdenum ore area in Guangdong Province. The TM images in this area are analyzed and applied in depth. The results showed that the spectral reflectance and TM grayscale of plant in molybdenum mining area were higher than those in control area. The shapes and shades of molybdenum mining area on TM false color composite image after K-L transformation were all significantly higher than those in control area However, the TM image characteristics in the study area are mainly affected by the aluminum content and chlorophyll content in plant leaves. The results of this study provide a theoretical basis for biogeochemical remote sensing prospecting in the vegetation coverage area.
