西藏玉龙铜矿开发对区域水环境影响分析

西藏玉龙铜矿是世界级特大型铜矿，目前即将开采。矿区位于海拔4 800多米的青藏高原，地处长江上游自然保护区,生态环境脆弱。矿区位于一个完整水文地质单元内的区域地下水补给区，地下水与地表水垂直交替运动频繁，水力联系密切。评价了区域地表水、地下水环境质量，通过江西省德兴铜矿开发过程中的环境问题类比，分析了矿山开发对区域水环境的影响，根据区域水文地质条件，从保护水环境角度，对玉龙铜矿开发提出了几点防止污染扩散的建议，以利于资源与环境的可持续发展。

INFLUENCE OF REGIONAL WATER ENVIRONMENT ON THE EXPLOITATION OF YULONG COPPER MINE IN TIBET

Yulong Copper Mine in Tibet Autonomous Region is a super-large copper mine in the world,and it will recently be exploited after being found about 40 years ago.The mine located in the nature reserve area of the upstream of the Changjiang River,where the eco-environment is very vulnerable because of being in Qinghai-Tibet Plateau with the altitude about 4 800 meters above sea level.The mine is also located in the recharge area of the hydrogeological unit.The vertical exchange of water occurs frequently due to the hydraulic connection between surface-water and groundwater in the area.The authors estimated the environmental quality of surface-water and groundwater,and analyzed the influence on regional water environment due to the exploitation of the mine.In order to achieve the sustainable development,some suggestions to the exploitation of the mine have made to prevent the polluted groundwater scope extending for the protection of the water environment according to the condition of regional hydrogeology.
