Abstract: In order to clarify the ecological restoration effect of Beijing Wangping Coal Mine.Based on the remote sensing image data of Landsat from 1990 to 2021, remote sensing ecological index(RSEI) was used to evaluate the effect of the ecological restoration project in Wangping coal mining area in Beijing, and combined with GM (1, 1) model, dynamic monitoring, spatio-temporal analysis and prediction of ecological environment quality in the study area were carried out in order to provide reference for the management of mine ecological restoration project.The results show that from 1990 to 2021, the ecological environment quality of Wangping Coal Mine shows a trend of "first decreasing, then rising".From 1990 to 2001, the areas with poor RSEI grade in the study area are concentrated in the northeast and southwest, and after the ecological restoration project is carried out, the ecological environment quality of Wangping Coal Mine is improved year by year, and a small number of poor areas are concentrated in the border area of the northeast.Based on the prediction of RSEI in Wangping Coal Mine, it is expected that the RSEI will reach 0.826 in 2025, and the ecological environment quality of the study area will reach the "excellent" level, indicating that the effect of the mine ecological restoration project is remarkable.
