摘 要:人类大规模地进行矿山开采造成生态环境问题,导致土壤发生变化,并引起矿山环境发生变化,矿区废弃土土壤恢复有利于该地区矿山环境的改进.在野外实测光谱的基础上,对江西德兴矿区废弃土土壤恢复潜力进行分析,并结合Hyperion高光谱数据,通过光谱吸收指数法反演铁离子含量、粘土矿物含量和有机质含量.结果显示,在德兴矿区一号坝、二号坝、四号坝和铜矿的土壤有益成分相对较低.铁、粘土矿物和有机质含量高值区主要分布为有林地,说明该区域土壤质量较好;一号、二号、四号尾矿库、废石场及选矿厂等地区,由于矿山的开采活动破坏了原有的土壤,土地耕种存在一定的难度,应采取相应的工程、生物和区域生态环境的改良等措施对土壤进行恢复治理.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 ana- lyzed 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, ⅣTailing Pond and copper mine, whereas they are high in the forest, which indicates the soil in the mining areas has been ruined due to explo- ration 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.
