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.
