Evaluation of Land Use Coordination Degree in Changsha Based on PSR Model

To analyze the land use coordination degree from 2001 to 2010 in Changsha,the evaluation system of land use coordination degree based on PSR model was constructed and the weight was determined by entropy method.The results indicated that the land use coordination degree in Changsha showed a rising trend,which meant that the land use system was developing in the direction of sustainability.The results were significant to identify problems existed in the current land use and reasonable and pertinent solutions were proposed to promote the coordination use of land.
