Abstract
The mining activity in Jinchuan has a history of many years. Copper and nickel mining not only plays a supporting role in the local social and economic development, but also has a significant impact on the ecological environment of the region. Based on Landsat series remote sensing data from 1994 to 2024, the impacts of copper and nickel mining on ecological environment in Jinchuan region were studied. Then, the characteristics of ecological environment and temporal and spatial changes were analyzed by using remote sensing Ecological index (RSEI). The results show that the environmental change is related to mining exploitation and annual precipitation. From 1994 to 2024, the overall ecological quality of the study area has improved. Areas with improved ecological quality are mainly distributed in the northeast. In a few areas in the south where mining activities are concentrated, the ecological quality has declined. This change is mainly due to large-scale underground mining, and necessary measures should be taken to improve the environmental quality.
