Abstract: 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.
