Abstract:: Based on the principle of ecological footprint and several extended models, the trends of PRED system in Jiangxi province were analyzed for the purpose of regional sustainable development. The results showed that, from 1980 to 2006, population increased from 3.27×10⁷ to 4.34×10⁷, yet eco-capacity of population decreased from 2.16×10⁷ to 1.51×10⁷, so that eco-overload population increased from 1.11×10⁷ to 2.8×10⁷, and the eco-overload population increased from 33.87% to 65.13%; Ecological footprint increased from 1.439 hm² per capita to 1.950 9 hm² per capita, whereas, biocapacity declined from 0.951 7 hm² per capita to 0.680 2 hm² per capita. Therefore, the ecological tension index increased from 1.26 to 2.05, and the grade of ecological safety grade turned from ‘a little danger’ to ‘at risk’ level. The ecological economic coordination index decreased from 0.51 to 0.43.The results revealed that the development of Jiangxi province is unsustainable.
