Taking Donghe District, Baotou City, Inner Mongolia Autonomous Region as an example, research on land use change and its ecological environment response was carried out to provide theoretical support for the coordinated development of regional economy and ecological environment. Based on Landsat 4, 5 TM images from 1990 to 2010 and Landsat 8 OLI satellite remote sensing images from 2013 to 2018 to obtain land use maps, the land use transfer matrix explored the changes in land use and its ecological environment response in Donghe District from 1990 to 2018. The research results show that the urban development of Donghe District is gradually expanding to the northwest and southeast, and the area of residential and commercial service land has increased significantly in these two directions; the area of unused land has gradually decreased after soil improvement; the area of arable land has decreased in general; vegetation The area of the water body has gradually increased in recent years; the area of the water body has remained balanced as a whole. The quality of the ecological environment in Donghe District has improved.
