Remote sensing data with a high spatial resolution can be used to quickly ascertain the current status of the geological environment of mines in China,yielding objective and accurate results.By comparing 2020-2021 remote sensing images of 169 districts,counties,and cities in Hebei Province,728 patches signaling suspected lands destroyed in mines were identified through interpretation.In 2021,the newly rehabilitated areas of the mining environment in Hebei Province reached 1 305.51 hm2,while the newly increased lands destroyed by mining were 932.13 hm2,resulting in a net increase of 373.38 hm2 in lands attributed to the geological environment rehabilitation.These results indicate the general achievement of mining while rehabilitating.Based on a preliminary analysis of the current status of the geological environment of mines in Hebei Province and existing primary issues,this study proposed countermeasures and recommendations for future rehabilitation efforts.The results of this study will provide foundational data and technical support for managing the geological environment of mines in Hebei Province and evaluating the effectiveness of mine greening initiatives.
