摘要
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。
The paper discusses the abnormal biogeochemical characteristics of Mo-deposit in Lake Dinhu,the plants spectrum characteristics,mechanisms of TM imagecharacteristics,and research the biogeochemical characteristics on TM images.Establishthe theorytical basis of biogeochemical remote sensing prospect for regions coveredby plants.The results show that the gray Level on TM image in Mo deposit area are hig-her than the background level, the abnormal colour in the TM false colour compo-site image of Mo ore-field is different from background’s.The TM gray level hasa direct bearing in the spectral reflectance of the plants.The main mechanism ofTM image cbaracteristics is Mo content and chlorophyll of plants.
