中文摘要:
      本文依托项目《西藏多龙矿床技术经济与环境综合评价》,利用高分二号、资源三号及landsat8等多源遥感数据对西藏多龙矿区生态地质环境进行调查研究。通过遥感技术与实地调查结合,查明了矿区生态地质环境现状,取得了涵盖人类活动、矿山地质活动、河流湖泊现状、植被覆盖与荒漠化情况等专题成果。研究结果表明,砂金矿开采及尾矿堆积物给当地生态环境造成不可逆破坏,同时探槽、钻孔及地表金属污染等也给生态环境带来一定程度的影响。通过对目前中国矿储量第一的多龙铜多金属矿床进行开发前全面、综合的生态地质环境调查研究,能够为藏北矿山开发对生态地质环境的影响评估提供了科学依据,为西藏多龙矿区建设绿色矿山和绿色开发提供建议及决策依据。
英文摘要:
      Based on the project of “Technical Economy and Environment Evaluation of the Duolong Deposit in Tibet”, multi-source remote sensing data including Gaofen-2(GF-2), Ziyuan-3(ZY-3) and Landsat8 were used to investigate the ecologic and geological environment in the Duolong mining area, Tibet. Combining remote sensing and field investigations, the current situation of the ecologic and geological environment such as human activities, mining activities, rivers and lakes, vegetation and desertification conditions are clarified. The research results indicate that gold mining and its tailings have caused irreversible damage to the local ecological environment; at the same time, the exploratory trench, drilling and pollution of metal oxide of the surface have also made a certain degree of influence. The study of ecologic and geological environment of the Duolong polymetallic deposit which has the No.1 mine reserves in China highlights the fragility of the ecological environment in Tibet. It can provide good suggestions and evidence for decision making in the green-mine construction and exploitation of the Duolong mining area, Tibet.
