Outline
To scientifically evaluate the effectiveness of ecological restoration in open-pit mining areas, a comprehensive assessment system comprising five indicators, including vegetation coverage, soil moisture, soil and water conservation, air quality and landscape ecological risk, was established from both macro and micro perspectives, based on multi-source data such as remote sensing, precipitation, and soil information. Taking the Quzhai mining area for cement in Luquan, Shijiazhuang as the experimental area, quantitative assessment of ecological restoration status from 2021 to 2023 was carried out. The results show that from 2021 to 2023, the overall vegetation coverage in the mining area increases, soil moisture improves, soil erosion decreases, air quality improves, and the proportion of areas with "good" comprehensive restoration effects increases from 47.38% to 57.74%, reflecting the overall effectiveness of restoration measures. However, the proportion of "relatively poor" and "poor" level areas has also increases, mainly due to ecological risks caused by local landscape fragmentation and land use type conversion. Therefore, it is recommended to implement refined management for high-risk areas, as well as optimize vegetation configuration and landscape connectivity, in order to enhance the overall quality and sustainability of ecological restoration in mining areas. The evaluation method constructed in this study can provide a reference for monitoring, assessment, and scientific management of ecological restoration in mining areas.
