Restoration Potential of Abandoned Soil at Dexing Mine of Jiangxi Province Based on Hyperion Data

Deterioration of soil quality and ecological environment caused by large scale mining poses as a serious threat to the life and social development. Based on measured data of soil in Dexing mining, the restoration potential of abandoned soil is analyzed in this study by using mathematics model and hyperion data to derive the iron ion, clay minerals and organic matter in the abandoned soil. The results show that the favorable contents of soil is low in Ⅰ Tailing Pond, Ⅱ Tailing Pond, Ⅳ Tailing Pond and copper mine, whereas they are high in the forest, which indicates the soil in the mining areas has been ruined due to exploration and development of mining while the soil is better in woods So it is necessary to reclaim the mining wasteland around mining areas after exploitation, and then restore the mining environment by improving soil quality, rational land planning, and close monitoring of the soil quality of mines.
