| 摘 要： | 西藏自治区地域广,湖泊多,盐湖矿产资源十分丰富,但调查研究程度较低。采用常规调查方法,周期长、费用高、难度大。以TM(ETM+)数据为主要信息源,采用波段合成、密度分割、比值处理等方法进行信息提取,取得了良好效果。圈划出的成矿远景区准确、可靠,经验证新发现了一批盐类矿产地。

| Abstract: | Abundant salt lake ore deposits are developed in vast rural areas of Tibet, but with very insufficient investigation. It is very difficult to conduct the exploration work by the traditional geological surveying methods in that they are very expensive and time-consuming. The remote sensing information extraction of modern salt lake ore deposits in Tibet based on TM(ETM~ ) data, color synthesis, density segmentation and ratio transformation has turned out to be effective. A number of perspective areas proposed on such a basis proved to be reliable, and several halide ore fields were found through verification. The remote sensing information extraction is indeed an ideal method for rapid appraisal of salt lake ore deposits in high-altitude regions of western China. |
