目前,我国金属尾矿的综合利用率很低,金属尾矿的大量堆存占用了土地、污染了环境。随着土地资源紧缺、生态环境污染等问题的日益突出,金属尾矿库复垦为废弃金属尾矿库的闭库治理提供了新思路,而GIS又为金属尾矿库复垦潜力评价提供了便捷工具。本文论述了金属尾矿库复垦潜力的评价指标及基于模糊层次分析法的评价模型,最后说明了GIS在金属尾矿库复垦潜力评价中的应用。
At present, the comprehensive utilization rate of metal tailings in our country is very low, a large amount of metal tailings piles up land and pollutes the environment. With the shortage of land resources and the increasingly prominent problems of ecological environment pollution, reclamation of metal tailings ponds provides a new idea for the closure of abandoned metal tailings ponds, and GIS provides the potential for reclamation of metal tailings ponds Convenient tools. This paper discusses the evaluation index of reclamation potential of metal tailing pond and evaluation model based on fuzzy analytic hierarchy process. Finally, the application of GIS in the evaluation of reclamation potential of metal tailing pond is illustrated.
