高原高寒砂金矿区生态修复治理模式与关键技术

Ecological Restoration Management Model and Key Technologies in Plateau Alpine Placer Gold Mining Areas

我国西藏地区历史遗留废弃矿山数量众多,因其地处高原高寒,生态修复难度大、周期长。该文以西藏某矿区为例,针对高原高寒矿区面临的地质安全隐患、草地退化、土地损坏、水系破坏、水土流失等矿山生态问题,基于辅助再生、后期管护和监测的综合技术措施等关键技术,提出水系重建与分区治理的模式,可为高原高寒地区废弃矿山生态环境修复提供一定的参考价值。

There are a large number of abandoned mines left over from history in Tibet,my country.Because it is located on a plateau and cold,ecological restoration is difficult and takes a long time.This article takes a mining area in Tibet as an example.In view of the geological safety hazards,grassland degradation,land damage,water system damage,water and soil erosion and other mining ecological problems faced by plateau alpine mining areas,comprehensive technical measures based on assisted regeneration,post-management and monitoring are key.technology,and propose a water system reconstruction and zoning management model,which will provide certain reference value for the future restoration of the ecological environment of abandoned mines in plateau and alpine areas.
