这项研究利用遥感调查石棉开采造成的退化程度，并监测南非maefe和Mathabatha地区矿山恢复的进展情况。采用图像差分法（NDVI）对研究区植被状况进行评价。结果表明，maefe和Mathabatha的植被均呈正负增长。这项研究有助于确定需要进一步修复的区域。
This study employs remote sensing to investigate the extent of degradation caused by asbestos mining, and to monitor the progress of mine rehabilitation in the Mafefe and Mathabatha areas in South Africa. Image differencing method (NDVI) was used to assess the condition of vegetation in the study area. Results show both positive and negative increase in vegetation at Mafefe and Mathabatha. The study helps in identifying areas that needs further rehabilitation.
