Based on the calculation results of pollution footprint, environmental carrying capacity and pollution deficit/surplus in Jiangxi Province from 2004 to 2015, the environmental sustainability was dynamically evaluated in Jiangxi Province from 2004 to 2015 based on a designed environmental sustainability standard with the ratio of pollution deficit/surplus to environmental pollution footprint. It was shown that Jiangxi Province was in the pollution surplus status during 2004 to 2015, which was derived from solid waste pollution surplus and atmospheric pollution surplus, while the water environment has been in pollution deficit. It can be seen that the environmental sustainability of Jiangxi was middle from 2005 to 2007 and strong from 2008 to 2015. Meanwhile, a pollution footprint prediction model ( y = -8260.6 x 2 + 62750 x + 5×10 6 .) was built to predict the pollution footprint trend of Jiangxi Province in the next five years, and that based on the environmental pollution footprint of Jiangxi Province from 2004 to 2015. It showed that the pollution footprint of Jiangxi Province would drop from 4563473.60 hm 2 in 2016 to 3889286.40hm 2 in 2020.
