Abstract: From the perspective of system theory, all the elements and their structural characteristics in the regional ecological-economic systems of Hunan province were analyzed, and an evaluation index system was constructed. Quantitative evaluation model was used to analyze the coupling status of the regional systems. The results showed that in 1996-2006, the integrated supporting ability of Hunan Province raised logarithmically, while the integrated consumption level increased exponentially, indicating the non-synchronous development of them. However, the coupling degree increased rapidly, with an average annual increment of 4.89 degrees. From 2008, Hunan Province shall enter the period of over-exploitation. Though the Province has richer resources, it doesn’t possess a strong material base of over-exploitation. Therefore, it’s needed to modify the economic growth mode and adjust industrial structure, and to overcome the deficiencies in developing export-oriented economy.
