In this paper, the land use changes of Jinan City based on Landsat 5 in 2009 and Landsat 8 images in 2014 were described. The images were reprocessed by radiometric calibration, geometric correction, image enhancement, and then the land use changes information were extracted by supervised classification, which was classified by six samples, including cultivated land, forest land, construction land, water system and unused land, then transfer matrix was showed. The results indicate that from 2009 to 2014, the area of construction land, the grass land and water system has been decreasing with the area of cultivated land, forest land and unused land increasing. The cultivated land has suffered the most, and construction land has increased the most.
