Eco-Geological Environment Carrying Capacity and Resource and Environmental Characteristics of Lithium Ore Belt in Western Sichuan

This is an essay in the field of earth sciences. The lithium belt in West Sichuanis the richest area of hard rock lithium resources in China, but the ecological and geological environment in the belt is fragile, so the coordinated development of resources, environment and economy has been a difficult problem for the deep development of regional resources. This paper systematically compares the natural resources, mineral resources, geological environment characteristics and the main environmental geological problems in the lithium belt, constructs an ecological and geological environment carrying capacity evaluation index system based on three subsystems: geological environment, ecological environment and social environment, selects and obtains 19 basic evaluation index data information, and carries out a region-wide carrying capacity evaluation. The results show that: the geological environment of the west Sichuan lithium belt is relatively safe and stable, the existing mining activities in the belt do not have a significant impact on the regional ecological environment, and the impact of human production and life is limited in scope. The proportion of the country area with medium and above carrying capacity reaches 79.16%, the ecological and geological environment carrying capacity in the lithium resource concentration area is high, and the overall ecological and geological environment is in good condition.
