离子吸附型稀土矿资源潜力遥感定量预测——基于SPOT5数据的地貌研究

Remote Sensing Quantitative Forecast of the Potential of Ion Adsorption Type Rare Earth Resources:Land Form Research Based on SPOT 5 Data

为了探讨现代地貌遥感信息的示矿意义,以广东省全境所涉及的1∶5万标准图幅(共546幅)范围为研究区,采用SPOT 5卫星遥感数据进行地貌的解译和定位,查明了区内地貌类型及其分布特征,获取了有效的示矿地貌信息。该成果可为广东省离子吸附型稀土矿勘查部署和矿产资源开发提供借鉴和指导。

In order to probe into the remote sensing ore indicating significance of land form,the authors adopted 546 sheets of 1∶ 50 000 standard maps of Guangdong Province as the study area,used the data of SPOT 5 remote sensing to carry out the extraction and precise orientation of the land form.As a result,the land form type and distribution characteristics of the study area were detected,and effective ore indicating information of land form was obtained.The result has certain reference and guidance value for prospecting and exploiting rare earth resources in Guangdong Province.
