The Fengfeng mining area is an important coal-producing area in China and crucial environmental problems have been caused by large-scale exploitation of coal mines. The spatio-temporal evolution and driving factors of the ecological environment quality in this area must be explored for promoting the transformation of coal-based cities. Based on Landsat data of the Google earth engine (GEE) platform, this study constructed a new remote sensing-based ecological index (RSEInew) for the Fengfeng mining area from 2000 to 2020.
