研究五公里铜矿尾矿库无土覆盖建立植被和毛家湾铜矿尾矿库有土覆盖农作物种植。结果表明 ,铜矿尾沙上直接种植是一种经济有效的复垦方法 ,草、灌木和乔木相结合可以形成很好的植被覆盖 ,大大改善了库区的生态环境。用少量黄土与尾砂混合覆盖 ,复垦投入少、作物产量高、作物可以食用 。
This paper deals with the scientific aspects of the rehabilitation of copper mine tailings for vegetation and agricultural applied to the two pilot sites, Wugongli Tailings Ponds in Anhui Province and Maojiawan Tailings Pond in Shanxi Province The results of the field trials show that vegetation with grass, shrubs and trees on the no soil cover tailing is cheaper and effective way for Wugongli Tailings Ponds as improving largely the environment of the tailings pond area At Maojiawan Tailings Pond, it is the best way to cover a little soil mixed with tailings for the tailings amelioration according to the low rehabilitation cost, high crops yields and the crops safe to eat
