摘要： 采用直接植被技术对大宝山矿新山片区2.5×10⁵ m²的排土场进行了生态修复。调查结果显示，修复1 年后该
区域的土壤pH 由强酸性上升至中性以上，并且减少了重金属元素的溶出，外排水中的铅、锌、铜、镉等重金属含量下
降均在90%以上。植被整体覆盖度达到97%，显著改善了区域环境质量，并实现了良好的水土保持效果。以上结果表
明，直接植被技术是一种经济有效、值得推广的矿山修复技术，有助于提升矿山碳汇功能。

Abstract: The direct vegetation technology was used to carry out ecological restoration on 2.5 ×10⁵ m² of Xinshan area in
Dabaoshan Mine. The results showed that the soil pH of the area increased from strong acidity to neutral after one year of
restoration, and the leaching of heavy metals was reduced. The content of heavy metals such as plumbum, zinc, cuprum, cadmium
in the external drainage decreased by more than 90%. The overall vegetation coverage reached 97%, which significantly improved
the regional environmental quality and achieved good soil and water conservation effect. The above results indicate that direct
vegetation technology is cost-effective and worth promoting, which can help to improve the carbon sink function of the mine.
