Abstract: Ecological footprint is a method for measure sustainable development degree of a country or region, quantitatively reflect the destructiveness and influence degree of human activity on ecological environment. Based on simple explanation of conventional modle of ecological footprint, put forward a modified modle by combining EMA with traditional ecological footprint of calculation, analysis the ecological footprint of Fuzhou city in 2006. The results show that this year, the average ecological footprint of Fuzhou was 1.29 hm2, the average ecological carrying capacity was 0.17 hm2, and the ecological deficit was 1.12 hm2,Fuzhou was unsustainable at present, which conforms to the result of conventional method. But the modified modle got more reasonable factors and give a more realistic picture of resource utilization situation and sustainable development ability, compared to the conventional one.
