Geo-information maps use simple language and graphics to express complex geographical phenomena, and provide an effective means for spatial analysis of land use. This article uses Landsat 8 OLI in Zhaozhou County in 2013 and 2020 as the main data source, with the support of RS and GIS technology to process the land use data in Zhaozhou County, conduct spatial analysis and explore its temporal and spatial changes. The results show that: from the current land use map, Zhaozhou County is dominated by cultivated land, from the analysis of the land use change TUPU, we can see that grassland and unused land are increasing, and the mainly transfer map is from cultivated land to unused land and cultivated land →grassland with a transfer area of 354.22km 2 ; the largest new grassland area was from 2013 to 2010, mainly from the transfer of cultivated land, forestland and construction land. Overall, the land use pattern tended to be stable from 2013 to 2020.
