基于IKONOS数据的赣南离子吸附型稀土矿非法开采监测研究

摘要

Unauthorized mining of ion-absorbed rare earth ore deposits have become more and more serious with the rising of the price of rare earth. The quick and accurate investigation of unauthorized mining has thus become government administrators’ major concern. High resolution remote sensing technology provides an idea for solving this problem. In this paper, ion-absorbed rare earth ore district in Xunwu area of south Jiangxi was selected as the study area, and IKONOS remote sensing data was used for investigation. The interpretation criteria were built with the help of the mining right data, and the vital monitoring areas were mentioned using the geological rock mass data. The results indicate that high resolution remote sensing processing can provide a good method for quick, accurate and dynamic investigation of ion-absorbed rare earth ore deposits.%随着稀土价值的不断攀升，稀土资源乱采滥挖现象日益严重，如何快速准确地进行稀土矿山非法开采监测成为相关政府部门管理的重中之重，高空间分辨率遥感技术为解决上述问题提供了思路。本文选取赣南寻乌地区离子吸附型稀土矿区为研究区，运用IKONOS遥感数据结合矿权资料建立了离子吸附型稀土矿山非法开采解译标志，结合地质岩体资料分析了稀土矿山开采重点监测区域。研究表明高空间分辨率遥感数据处理与分析为离子吸附型稀土矿矿山非法开采快速、准确、动态监测提供了良好的技术手段。
