摘　　要：能值—生态足迹是运用能值转换率和区域能值密度建立修正的生态足迹模型,能更加精确地反映区域生态经济发展状况。运用改进的能值—生态足迹模型,探讨了2005—2010年大连市动态生态足迹。模型分析得出,2005—2010年大连能值—生态承载力均低于能值—生态足迹,处于生态赤字状态。6年间生态赤字由2005年的1.51hm2增加到了2010年的2.59hm2,且在生态足迹构成中能源足迹所占比重逐年增大。Emergy - Based Ecological Footprint which was the improvement of traditional ecological footprint model, using the emergy transfomity and area emergy density. The emergy - based ecological footprint model could explain the status of the development of ecological economy accurately. In this paper, the authors applied the improved emergy- based ecological footprint mode] to analyze the dynamic ecological footprint of Dalian City from 2005 to 2010. The results showed that the emergy - based ecological carrying capacity of Dalian was below the emergy - based ecological foot- print from 2005 to 2010 and was in the ecological deficit state. In six years, the ecological deficit was increased from 1.51 hm2 in 2005 to 2.59 hm^2 in 2010. The energy resources＇ footprint was increasing year by year in the composition of ecological footprint.
