    Monitor and analyze the spatial and temporal changes in ecological environment quality and its influencing factors to provide theoretical support for the rational formulation of restoration decisions in this region and orderly carry out restoration work This paper takes Xilingol League Inner Mongolia as the research area and uses the Google Earth Engine GEE platform to build improved remote sensing ecological index IRSEI model to monitor and evaluate the changes in the ecological environment quality in the Xilingol League from 2001 to 2021 The results show that 1 From 2001 to 2021 the mean values of the improved remote sensing ecological index IRSEI and the remote sensing ecological index RSEI in Xilingol League first increased then decreased and then increased again Areas with poor and more poorer ecological quality were mainly concentrated in the southwest of the study area accounting for 29%-37% Areas with good and excellent ecological quality were mainly distributed in the northeast accounting for 18%-27% The area proportion of regions with poorer ecological quality or worse was still larger than that of regions with goodecological quality and excellent 2 From 2001 to 2021 the proportion of the area where the overall ecological environment quality has improved reached 8 96% and the overall improvement ratio is slightly greater than the deterioration ratio 3 NDVI is the main ecological response factor and the average Q value of the 7 influencing factors is NDVI>NDBSI>WET>SI_T>LST Research shows that IRSEI can monitor regional ecological quality at low cost quickly and accurately and can better monitor long-term changes in ecological quality in mining cities providing theoretical support for the region to reasonably formulate restoration decisions and carry out restoration work in an orderly manner
