摘要:
烂泥沟金矿露天采坑挖损总面积约为0.461 km2，遵循因地制宜原则，将露天采坑560 m标高以上至最终境界线区域实施生态修复及植被重建。露天采坑生态修复采取分区开展，划分为地质遗迹保护区、覆土植被恢复区与自然生态恢复区等3个区域，主要治理措施包括喷灌系统、土壤重构、植被重建、截排水、植物维护等，目前植被覆盖率90 %以上，平台植物生长正常，具有可持续性。烂泥沟金矿露天采坑的生态修复经验可供同类型露天采坑生态修复工程借鉴。

Abstract:
The total land damage caused by open-pit mining in the Lannigou Gold Mine is approximately 0.461 km2.Following the principle of adapting to local conditions,ecological restoration and vegetation reconstruction has been implemented in the area from the open-pit mining area to the final boundary line above an elevation of 560 m.The ecological restoration of the open-pit mining area is carried out in different zones,including 3 areas,namely the geological heritage conservation zone,the overburden and vegetation restoration zone,and the natural ecological restoration zone.The main restoration measures include irrigation systems,soil reconstruction,vegetation reconstruction,drainage interception,and plant preservation.At present,the vegetation coverage is above 90 %,and platform plant growth is normal,indicating sustainability.The ecological restoration experience of the Lannigou Gold Mine open-pit mine can provide a reference for ecological restoration projects in the same industry.
