摘　　要：运用生态足迹模型计算得到了辽宁省1999～2008年间人均能源足迹由1.753 hm2增大到3.107 hm2,同期内人均生态足迹由2.847 hm2增大到4.729 hm2.约60%以上的生态影响是由能源消费造成的,并且能源消费造成的生态压力逐步增大.建立并运用人均能源足迹分解模型对辽宁省能源足迹计算结果进行了实证分析,发现该区域能源强度效应和能源结构效应对于生态压力下降的贡献不足以抵消由于经济发展水平的提高造成的生态影响,导致了辽宁省人均能源足迹呈现增加的趋势,特别是2003年以后增加趋势更加明显.提出了降低辽宁省人均能源足迹的对策.An EF（ecological footprint） model was used to calculate the per capita EEF（energy ecological footprint）,which increased from 1.753 to 3.107A4!hm2 in the period from 1999 to 2008 in Liaoning province,while the EF was in the range from 2.847 to 4.729A4!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.
