基于能值理论的福州市生态足迹分析

生态足迹是衡量一个国家或地区可持续发展程度的一种方法，定量反映人类活动对生态环境的影响和破坏程度。在对传统生态足迹模型进行简要分析的基础上,提出了基于能值分析理论的生态足迹计算的改进模型，对福州市的生态足迹进行计算及分析。结果表明，2006年福州市人均生态足迹为1.29 hm2，人均生态承载力为0.17 hm2，生态赤字为1.12 hm2，福州市的生态系统处于不可持续状态。与传统生态足迹模型计算结果进行比较研究，结果一致。但改进后的生态足迹模型更具合理性，更真实的反映了区域的生态资源利用状况和可持续发展能力。

Ecological Footprint Of Fuzhou Based On The Emergy Theory

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.
