| Research on Environmental Impacts of Lithium Development in Zhabuye Salt Lake, Tibet |
| Zhabuye Salt Lake is a unique natural crystalline lithium carbonate salt lake in the world, and it is the largest industrial production of lithium carbonate salt lake using solar pool technology in Tibet. The comprehensive study on the environmental impact of mining area will be beneficial for the rational and orderly development of salt lake resources. Using field investigation and remote sensing satellite technology, the environmental impact of the development of Zhabuye Salt Lake was systematically studied. The results show that the environmental impact modes mainly include resource damage, geological disaster and water and soil gas. The affected area is mainly distributed in roads, living and office areas, salt fields, sun pools, soil mining areas, drainage and brine drainage channels, etc. The affected area is about 16 km2, accounting for only 5.37% of the mining area. The environmental damage of Zhabuye Salt Lake mining area is local and controllable. Suggestions such as using lo-cal plants for land reclamation, using geomembrane to prevent channel penetration and filling subsidence with clay, building walls to prevent soil gas salinization, realizing effective water exchange between the north and South Lakes by increasing pipelines, and establishing long-term monitoring and early warning are put forward to provide reference for the green and sustainable development of Zhabuye Salt Lake. |
