【摘要】：离子吸附型稀土矿山开采不仅会占用及破坏土地资源,还会造成土地荒漠化等严重的地质环境问题,如何快速、准确、实时地进行稀土矿山监测,成为一个重要的科学问题。本文选取江西定南稀土矿区为研究区,以2015年高分一号数据为主要信息源,建立稀土矿山主要地物解译标志,开展稀土矿山占地现状调查;并结合2011年的Geoeye遥感数据,运用光谱角填图方法提取两期数据的土地荒漠化区域,开展稀土矿山土地荒漠化动态监测示范研究。研究结果表明遥感能够为稀土矿山监测提供良好的技术手段,且国产高分一号数据能够替代国外卫星数据在矿山监测中发挥重要作用。
[Abstract]:Ion adsorption rare earth mining will not only occupy and destroy land resources, but also cause serious geological and environmental problems such as land desertification. How to monitor rare earth mines quickly, accurately and in real time? It has become an important scientific problem. This paper selects Dingnan rare earth mining area in Jiangxi Province as the research area, taking the data of No. 1 in 2015 as the main information source, establishes the interpretation mark of the main features of rare earth mines, and carries out an investigation on the present situation of the rare earth mines. Combined with the Geoeye remote sensing data of 2011, the land desertification area of two-period data was extracted by the spectral angle mapping method. A demonstration study on dynamic monitoring of land desertification in rare earth mines has been carried out. The results show that remote sensing can provide a good technical means for monitoring rare earth mines. And domestic high score 1 data can replace foreign satellite data in mine monitoring play an important role.
