Based on the LANDSAT remote sensing image data of 2000, 2005, 2010 and 2015, this paper applies RS, GIS, mathematical statistics and other methods, mainly about land use transfer matrix, single land use dynamic and comprehensive land use dynamic to analyse land use change in Jining City during the period from 2000 to 2015. The results show that: (1) The transfer intensity of grass is gradually increasing. Dry land and house-site in the countryside are transferred largely into town house. The transfer between dry land and house-site in the countryside is obvious. The imported area of waters is always larger than the exported area in three periods. Retention rate of dry land has remained relatively high. In addition, the unutilized land retention rate varies greatly. (2) The single dynamic of paddy field, town house and unutilized land are large, indicating changes of these types are intensive; the lower dynamic of dry land and waters indicates the stability of these types is good. The comprehensive land use dynamics first decreased and then increased, indicating that the intensity of land use change in Jining City first decreased and then increased, and the overall land use change is large.
