- 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.
