Abstract:Setting Dong'e county as the study region, by using geographic information system technology, Excel software, and mathematical model, space and time changes have been studied quantitatively. By using land utilization dynamic model and land utilization degree space and time evolution model, dynamic changes of land utilization in Dong'e county have been studied as well, including land utilization quantity change analysis of various types, spatial variation analysis of structures, and change analysis of land utilization degree. Relative countermeasures have been put forward for sustainable land use in Dong'e county in the future.
