选择粤赣两省交界处为研究区，以资源一号02 C影像为主要数据源。首先在对资源一号02 C数据进行质量评价的基础上，通过多次试验选择合适的方法对数据进行预处理，制作满足稀土开采监测要求的遥感影像。然后参照以往稀土遥感监测研究成果并结合野外踏勘情况，建立合适的解译标志。再提取研究区的稀土开采图斑，并进行野外验证。最后，通过往年的影像提取稀土开采历史图斑，进行多期对比分析，对工作区近年来的稀土开采状况进行监测。研究表明，资源一号02C数据能较好满足稀土开采监测的要求，在我国南方地区应用具有典型意义。

In this article, the authors selected the boundaries of Guangdong Province and Jiangxi Province as the study area ,and used ZY1-02C remote sensing images as the main data source .The procedures are as follows.First, the researchers created the required remote sensing image for monitoring Rare Earth Mining (REE) based on several pretreatment testing with different preprocessing methods and quality e-valuation of the ZY1-02C data in study area.Then, a suitable interpretative symbol was established refer-ring to the previous experience of remote sensing monitoring of REE .After that, the mining spots of REE were extracted and outdoors validation was carried out .Finally, historical mining spots with former ima-ges were drawn and used for comparative analysis with spots of 2012 in order to monitor the mining condi-tions in recent years .The results of this research show that ZY-1 02C data can meet the requirements of monitoring of REE mining conditions and the research has typical significance in the application in the southern Chinese regions .
