| Environment Contamination Investigation of Ion-absorbed Rare Earth Ore Districts Based on IKONOS Remote Sensing Data: A Case Study of Xunwu Area in South Jiangxi |
| The mining of rare earth ore leads to a series of environmental problems. To solve the problem of environmental monitoring of the ion-absorbed rare earth ore districts in southern China, the authors selected Xunwu area in south Jiangxi as the study area, and used IKONOS remote sensing data for investigation. For the two main kinds of environmental problems in the ion-absorbed rare earth ore mining, i.e., land desertification and water pollution, the spectral angle mapping classification method was chosen to extract the land desertification place in the study area, and ISODATA unsupervised classification algorithm was used to estimate the contamination of the river near the ion-absorbed rare earth ore district. An analysis of the results and field survey show that high spatial resolution remote sensing technology can provide a good means for environmental investigation of the ion-absorbed rare earth ore district. |
