Abstract: An EF (ecological footprint) model was used to calculate the per capita EEF (energy ecological footprint), which increased from 1.753 to 3.107 hm² in the period from 1999 to 2008 in Liaoning province, while the EF was in the range from 2.847 to 4.729 hm². The results showed that EEF was over 60% of EF, and that the ecological pressure owing to energy consumption increased gradually. A per capita EEF decomposition model was developed and applied to the empirical analysis of the calculated results of EEF, and it was found that the contributive effects of the intensity and structure of energy on the decreasing ecological pressure is unable to offset the ecological hazard due to economic development, thus resulting in the increasing trend of per capita EEF, especially after the year 2003. Some measures are therefore suggested to take to decrease the per capita EEF.
